Welcome to this week’s installment of The Intelligence Brief… a controversy has erupted in recent days with the FCC’s approval of a proof-of-concept satellite that reflects daylight to Earth at night, in a move that has astronomers concerned. In our analysis, we’ll be looking at 1) the FCC’s approval of Reflect Orbital’s Eärendil-1 satellite, 2) what the company says about its sunlight mirror orbital technologies, 3) the sharp responses from the astronomical community, and 4) where things go from here as the demonstration satellite heads toward production.

FCC Approves Launch of Satellite Designed to Reflect Sunlight to Earth’s Nightside
This week, in a controversial ruling that has sky watchers (and others) concerned, the U.S. Federal Communications Commission (FCC) approved the launch of an experimental satellite crafted to reflect sunlight onto Earth after sunset.
The move has seen significant pushback from astronomers, who now warn that the technology would likely interfere with scientific observations and alter the natural appearance of the night sky.
Dubbed Eärendil 1, the satellite is being developed by the California-based Reflect Orbital as a proof-of-concept for the company’s larger, and potentially even more impactful vision: as many as 50,000 orbiting mirrors capable of directing sunlight to different regions on Earth.
While astronomers have expressed concern over the implementation of such orbital systems, the company says its satellites would offer the possibility for providing illumination after dark in select areas, which could be used to extend the operation hours for solar powered facilities.
Eärendil 1: A Case Study in Controversy
Branding itself as “the sunlight company,” Reflect Orbital says in a statement at its website that it aims to provide “clean, abundant energy available on demand,” because “reliable access to affordable energy is the foundation of human progress, economic growth, and a healthier planet.”
The satellite, which shares its name with Eärendil the Mariner, a character from J.R.R. Tolkien’s mythos, will carry an 18-by-18-meter (59-by-59-foot) reflective Mylar surface that unfolds in orbit after launch. Operating roughly 625 kilometers (390 miles) above Earth, the spacecraft is designed to redirect sunlight onto specific target areas of approximately five kilometers (three miles) in width.
Although many are sounding the alarm about the potential consequences of such technology, the Reflect Orbital says it maintains strict exclusion zones where astronomical operations or “sensitive areas” exist, and that its technology can be carefully deployed only to regions identified as target areas.
According to a FAQ page on the company’s website, the light produced by Eärendil 1 and future members of the company’s constellation will be “contained within the spot” among several other safety features it promotes. The company also says it can turn off the light quickly, and disable it at any time to prevent light from reaching Earth.
“The light is not bright enough to start fires or harm eyes,” the company’s FAQ page states, “even when viewed through a telescope, and cannot be concentrated past maximum natural sunlight irradiance.”
The company’s CEO, Ben Nowack, has argued the concept could improve the economics of solar power overall, allowing Earth-based power systems the ability to harvest additional sunlight before sunrise and after sunset.
Criticism Abounds
The proposal has drawn criticism from several groups, particularly the American Astronomical Society (AAS), which urged the FCC to reject the application.
“The American Astronomical Society (AAS) is dismayed by the Federal Communications Commission (FCC) decision on 9 July to grant a license to Reflect Orbital,” the organization said in a statement following the FCC ruling. “As the AAS expressed to the FCC, Reflect Orbital’s proposed satellite, which would reflect sunlight back to Earth at night, carries the potential for significant harm to our members and the broader community of those who depend on a dark night sky.”
“This harm could include damage to sensitive research telescope equipment, potential flash-blinding of pilots and drivers, and — as Reflect Orbital stated in its own FCC filings — potential permanent eye damage to anyone looking through a mid-sized telescope,” the AAS statement adds, noting what appears to be a sharp contrast between information contained in FCC filings, and that which appears on the company’s website.
Further, research cited by the AAS suggests that a full constellation of Reflect Orbital satellites could increase nighttime sky brightness by a factor of two to three, even at remote observatories, due to atmospheric scattering of the reflected light.
“While we fully support American technical innovation in space, this innovation cannot come at the cost of imperiling scientific research, which has been at the forefront of American innovation and global leadership for decades,” the AAS statement concludes.
Beyond FCC Authority
However, in the wording featured in the agency’s approval, the FCC concluded that such concerns fall outside its authority, which is primarily limited to regulating the use of radio-frequency spectrum, adding that it believes the overall likelihood of injury resulting from the launch of the proof-of-concept satellite to be low.
In the meantime, while the FCC’s approval marks an early win for Reflect Orbital, the company has said that it is planning to have independent research commissioned to help assess the technology’s environmental and scientific impacts. Additionally, the company says it plans to coordinate with the National Science Foundation to help ensure that its efforts align with those of the broader scientific community.
Fundamentally, the AAS’s disappointment—a view expressed by other members of the scientific community, argues that the ruling presents broader questions about who should oversee the environmental consequences of future space-based illumination projects, especially if such systems end up becoming more widespread in the years ahead.
“In the absence of another licensing agency that could take these considerations into account, we believe that it is critical for the FCC to consider all of the impacts of the satellite’s use case,” the AAS said in its statement this week.
If you’re looking for a power bank that can handle your iPhone, iPad, and even your MacBook Air, you usually need to spend at least $50. Not today: This Anker 24,000mAh 65W Portable Power Bank is just $35 today at Woot, half off its $70 MSRP.
With a massive 24,000mAh capacity, this power bank delivers roughly one full MacBook charge or about 4-5 charges for your smartphone. It’s more than enough to cover everything you need when you’re on the go, so you don’t have to look for a wall socket.
The charging setup holds up nicely, too. You get 65W total output across two USB-C ports, so you can power two devices at once. Recharging the pack itself is quick as well, as a 30W input tops it off in about 4.5 hours. That’s not super fast if you’re in a hurry, but if you plug it in overnight, you’ll even forget about it.
You have to be aware of a couple of things before buying. First of all, the two ports split power unevenly. One USB-C port maxes out at 45W, while the other caps at 20W. Therefore, you have to be well aware of how you’re distributing charging power on the go. This is also a no-frills battery, so you’ll need to bring your own cables.
For the price, those trade-offs are easy to live with. You’re paying for raw capacity and dependable output, not extra bells and whistles. At $35, this is a smart pick if you want big, reliable power for travel. Grab it while this deal still lasts.
We’ve rounded up the best MagSafe, Qi2, Qi2.2 25W, and MagSafe-compatible magnetic chargers, from the plain pad to multi-functional stands (up to six devices charged), and even the most colorful—from snap-on chargers and modular stands to foldable power banks and full charging desk mats.
Apple’s MagSafe technology, supported by all models of iPhone since the iPhone 12 (except the iPhone SE and 16e), presents a more efficient way of wirelessly charging compatible iPhones. MagSafe is the ring of magnets around the iPhone’s internal charging coil that senses compatible accessories and magnetically snaps securely into the most efficient charging position with the right accessories. With MagSafe, you’re less likely to wake up to find your phone wasn’t correctly placed on the wireless charger so didn’t charge at all!
Testing the best for you
We have tested a lot of magnetic chargers—MagSafe, Qi2 and Compatible—and here inform you which one will work best for you. There are simple magnetic wireless chargers, multi-device chargers for iPhone, Apple Watch and AirPods, travel chargers, car chargers and more.
Offering up to 25W power output in the right configuration, MagSafe charging is much faster than basic 7.5W magnetic wireless charging. The similar magentic Qi2 standard, supported by the iPhone 13-17 families (and unofficially the iPhone 12 but strangely not the latest 16e) offers similar 15W speed charging. Qi 2.2, also known as Qi2 25W, meets MagSafe at 25W for iPhone 16/17 series.
MagSafe or Qi2 certification
Apple certifies MagSafe accessories to ensures that the output charging is 15W for most iPhones, and up to 25W for iPhone 16 and 17 (with Apple’s latest MagSafe charger or chargers certified for Qi2 25W). Non-certified magnetic but “MagSafe-compatible” chargers are usually just 7.5W with a ring of magnets to hold your phone in place. Certified MagSafe chargers also have a single-wire NFC antenna that allows the iPhone to identify the device and a built-in magnetometer to prevent compass interference while you are using your iPhone while it’s charging.
In our tests, 15W MagSafe and Qi2 chargers are evenly matched for charging speeds. 7.5W MagSafe compatible chargers, as you might expect, take around twice as long—certainly in the early stages of charging. But don’t rule out 7.5W chargers as they are often high quality, nearly always noticeably cheaper and just take a while longer to fully charge an iPhone. The king of the hill is Apple’s new MagSafe charger and chargers based on the new Qi2 25W technology that are definitely faster at 25W, but only with iPhone 16 or later.
Foundry
Simple vs multi-device magnetic chargers
The most basic form of MagSafe or magnetic charger is the simple pad that latches on to the compatible iPhone. Some pads feature a pop-out arm so the iPhone can be propped up while charging. There are also products that can simultaneously charge an iPhone plus other Apple devices, such as an Apple Watch or wireless AirPods charging case. Note that the AirPods case must be of the wireless variety, and the original AirPods case lacked this functionality. The base of a multi-charger could also be used to charge a second iPhone but mostly not magnetically and at 5W rather than 7.5W, 15W, or 25W. Also see our round up of the Best Apple Watch chargers and stands.
Best simple MagSafe chargers
A simple MagSafe charging pad is the cheapest route to wireless iPhone charging. If you are going to the bother of connecting this product to a wall charger, why not just use a Lightning (iPhone 14 or earlier) or USB-C (iPhone 15 and up) cable direct to the iPhone? You can fast-charge an iPhone to 50% battery in under 30 minutes using a cable and just over that using a 25W charger, while it takes around 50 minutes to wirelessly charge iPhone from 0 to 50% using even 15W MagSafe.
That said, there are interesting options to choose from. After these we’ll look at more multi-functional MagSafe chargers.

The most obvious MagSafe Charger to buy for your Apple iPhone is, of course, the Apple MagSafe Charger. It’s the charger that Apple would have shipped with the iPhone if it did such things anymore. It’s as minimalist a design as you’d expect from Apple–it looks a lot like a giant Apple Watch Charger. You can also use it to charge your AirPods.
Apple’s latest version of this charger offers 15W Qi2 support and, more importantly, a faster 25W charging speed with iPhone 16 and later. It also added a 2-meter length option for $10/£10 more, which is very welcome. At least a 30W USB-C power adapter is required for 25W charging.
In our tests using the Apple MagSafe Charger we wirelessly powered up an iPhone 16 Pro from 0% to 50% in just over 30 minutes.
It can also charge your AirPods case (AirPods 2 or AirPods Pro), although not at the same time as the iPhone—for that, you’ll need at least a 2-in-1 wireless charger.
The standard 1m cable is too short to comfortably charge and use your iPhone at the same time, or maybe stretch from a power socket to a nearby table, so we recommend the 2m upgrade. Don’t forget that this Apple charger still requires a USB-C power adapter—at least 20W if you want 15W charging and at least 30W to enable 25W charging.

The Ugreen MagFlow Qi2 25W Magnetic Wireless Charging Pad isn’t too dissimilar to the 25W Apple MagSafe Charger except that it’s a fetching shade of what Apple would call Mist or Sky Blue. As such it would perfectly suit the iPhone 17 and iPhone Air of those shades.
Another difference is the length of cable and maybe 1.5m is a Goldilocks length for you if Apple’s 1m cable is too short and 2m cable too long.
Other than that, this simple charger matches the Apple pad for speed (25W for iPhone 16/17 and 15W for iPhone 12-15), and is more likely to be found discounted than the Apple either direct or on Amazon. It’s a solid alternative to Apple if any of these differences take your fancy.

Another basic magnetic charger, Anker’s Zolo Magnetic Wireless Charger Pad works just like the Apple pad, and also at a fast 15W—although it’s technology is Qi2 rather than Apple MagSafe. iPhone 16 and 17 owners should consider spending the extra on the Apple charger (reviewed above) for its special 25W charging speed. Owners of iPhone 15 or earlier can rest assured that this charger is as fast as the Apple one.
It works just as well, though, and is one of the cheaper premium magnetic chargers. The cable is a decent length at 1.5m—half again as long as that on the base model Apple MagSafe Charger pad, but not as long as on the top-end 2m Apple charger or the 2m Belkin MagSafe charger reviewed below.
Like Apple’s MagSafe Charger it can also charge your AirPods case (AirPods 2 or AirPods Pro) when the iPhone is removed.
In the U.S. Anker offers this charger only in a two-pack. A spare charger for downstairs, the office, bedroom, car and so on is always useful.

The 25W Belkin UltraCharge Magnetic Charger Pad is now just as fast as Apple’s charger for the iPhone 16/17 families, and comes with a long cable and handy pop-up stand. The cable is twice as long as Apple’s basic model, which makes using the phone much easier when charging. It’s also thicker nylon-braided cable with a handy integrated silicone cable tie.
Belkin sells two versions, one with a squarer back shape and one rounder—the difference is minimal. There’s also an option to buy with a 36W power adapter (for a very reasonable extra $10) included or just on its own if you already have a wall charger to use.
Again, a straight cable connection will be faster but we like the kickstand, which you don’t get with a standard cable connection.
There are a few very similar Belkin Charger Pads so make sure you get what you’re after. For example, there is a slower but slightly more affordable 15W BoostCharge Pro Magnetic Charging Pad with stand (Amazon or Amazon UK) and 7.5W MagSafe-compatible BoostCharge Charger Pad (Amazon U.S. and Amazon U.K.) that lacks the stand. If you just want a cheap MagSafe-compatible charging pad, this is a decent option. Be warned: Belkin also sells a Qi Wireless Charging Pad that lacks the magnetic connection so is not recommended as it will be picky where the phone is placed and slower to charge as a result.

It is less of an easy fit in a portrait (vertical) orientation as the bottom of the iPhone pushes the stand up onto its edge. It’s still stable but looks a little odd from the side.

While the Satechi 2-in-1 Foldable Qi2 and Belkin 2-in-1 25W wireless charging stands, reviewed above, can fold into a portable package, they are nowhere near as compact and lightweight (7.5oz / 212g) as Ugreen’s 2-in-1 MagFlow magnetic wireless charger, which folds down into a tiny pocketable cube (2.4 x 2.4 x 1.5 inches or 6 x 6 x 4cm).
It’s also as fast as you can get for wirelessly charging an iPhone 16 or 17; older iPhones charge at 15W.
Once open there’s a 5W Qi pad for AirPods and a 25W Qi2 pad for iPhone. A USB-C port on one side allows you to plug in your Apple Watch charging cable for 5W speedy charging, too—so you can almost call it a 3-in-1 except that you need a Watch charging cable to connect.
The iPhone-charging pad can be raised to about 3 inches (8cm), and can be angled to your preference.
Ugreen
Ugreen also sells a slightly cheaper aluminum gray $49 Qi2 2-in-1 Magnetic Charger that looks similar but charges the phone at a slower 15W, and a flatter 15W Qi2 MagFlow 2-in-1, both pictured above, that measures 4.6 x 2.2 x 0.9 inches (11.6 x 5.5 x 2.4cm) and will slip into a pocket easier than the cube shape.

Although it doesn’t include an Apple Watch charging module, there is a 5W USB-C port that you can connect your Watch-charging cable into and charge all three devices simultaneously.
As a 2-in-1 solution it is cheaper and better suited for those who haven’t succumbed to the Apple Watch.
Being certified as Qi2 means that it can wirelessly charge at the same 15W as official MagSafe chargers but not 25W like the Apple MagSafe Charger or newer Qi2 25W chargers can for the iPhone 16 and later.
The pad is reassuringly heavy so you won’t pull it off your bedside table when you remove your iPhone from the magnetic pad. This makes it less obviously portable, but it’s small and flat enough to slip into a backpack.
As it’s a pad you can’t angle the phone into StandBy mode. If you want to more easily see the time on your nightstand, consider one of the charging stands reviewed above. It ships with a 30W USB-C wall charger and cable.

Unless you own expensive burner iPhones, this charger is made for homes or offices where friends, family and colleagues can charge their iPhones at the same time and in the same place using just one power socket. We didn’t include it in our 3-in-1 roundup (see this immediately below) as it doesn’t charge the Apple Watch, although it can certainly power up three devices at the same time.
It’s the only magnetic wireless charging stand we’ve tested that charges two iPhones on a proper stand, and there’s a 3.5W Qi wireless charging pad underneath for one set of AirPods—your pal’s earbuds will have to wait their turn. The charging pads are not adjustable but the angle is perfect for screen viewing.
The SwanScout 706M is MagSafe Compatible rather than certified MagSafe or Qi2 so its wireless charging speed is limited to 7.5W or 10W shared across the two iPhone pads. That makes it a slow charge but this is fine for a nightstand where you have several hours for charging.
Best 3-in-1 MagSafe chargers
If you have brought full-in on the Apple product ecosystem, and have iPhone, AirPods and an Apple Watch, there are some great 3-in-1 magnetic chargers that will wirelessly charge all three devices simultaneously. 3-in-1 charging stands save you precious desk space or keep your nightstand or bedside table clear of clutter, while ensuring that you don’t run out of power during the day.

In a technology it’s called StealthCharge, Mophie has cleverly moved the the hottest components from the charging pad itself (in direct contact with the phone) to the product’s base. In effect, the base now serves as a heat sink to dissipate heat more efficiently. This means there’s no need for a noisy fan to keep the phone cool enough to receive a steady charge and maintain the fastest speeds.
It’s a small-footprint but tall charger, available in three colors, as well as a 4-in-1 version (reviewed here further down) that boasts a hidden 60W retractable USB-C cable that you can use to charge another USB-C device such as your MacBook.

The first Qi2 25W charger in the Macworld labs was Belkin’s UltraCharge Pro 3-in-1 Magnetic Charging Dock. Not only is this a super-speedy 3-in-1 charger, it’s a striking low-profile design with adjustable charging pad angling off a chrome-finished metal frame. The certified Apple Watch charger is fast, too.
Qi2 25W (sometimes known as Qi 2.2) takes wireless charging from its 15W maximum to a heady 25W. Previously only possible on the latest version of Apple’s own MagSafe Charger, 25W theoretically moves a 50% iPhone refill from 45 to just 25 minutes but environmental conditions such as temperature and the power used by the phone while being charged mean that 30-35 minutes is a more more realistic charging time for 25W. For wireless charging that’s still a big leap forward.
As 25W is achievable only with an iPhone 16 or 17 running at least iOS 26 it’s a new frontier for iPhone users. 25W chargers still work with earlier iPhones (12-15) but are pegged back at Qi2’s 15W maximum. All will feel the benefit of Belkin’s built-in active cooling ChillBoost fan.

This Anker Prime 3-in-1 iPhone stand takes speedy Qi2 25W charging to a traditionally elegant arm-based charging station design where the iPhone and Watch charging pads are suspended from the circular base. In our tests it came out fastest of all the 25W wireless chargers we have run through their paces—charging an iPhone 16 Pro to 50% in just 28 minutes.
The iPhone and Watch charging pads are held high on chrome arms that are angled for viewing angle and overall stand stability. We appreciate that the angle of the iPhone pad can be adjusted to your liking. The AirPods Qi pad is in the base beneath the arms and behind a neat and informative 1.65-inch HD smart display that is the first we’ve seen on such a stand. This is combined with app connectivity, so you can view power flow, charging temperature, and more. This where you can set the charging mode and also customize the clock face.

More affordable than the Anker 3-in-1 but slower at 15W, Belkin’s wireless charging stand is similarly elegant and with an even more adjustable iPhone pad (90 degrees vs Anker’s 80). The arm placement is different but not functionally, so the design choice at least come down to personal preference.
While the iPhone charging is slower (15W vs 25W) the Watch and AirPods will power up in roughly the same time as you get with the Anker 3-in-1. If you are charging your iPhone overnight or have more time on your hand, the speed difference shouldn’t matter. It also lacks the Anker’s smart display if you like to keep up to date with exactly how fast your devices are charging.

Another Qi2 25W solution, the ESR 3-in-1 25W Charging Station offers fast 25W iPhone wireless charging and 5W Apple Watch fast charging in a small-footprint design (3.4-inch square base) that tucks the Apple Watch charger at the back. The Watch charger is detachable, meaning you can remove it and take it with you to plug directly into any USB-C charging port. This is a useful option missing from most other 3-in-1 chargers, although the opportunity to later mislay it must be considered.
Where this charger excels is wireless charging speed. As with the Belkin UltraCharge Pro, reviewed above, it uses a fan-based cooling technology (ESR’s is called CryoBoost) with advanced heat-dissipation that makes the operation more battery friendly—resulting in significantly faster charging times.
The ESR’s Qi 2.2 pad is not adjustable, although you can position the iPhone in either landscape (StandBy) or portrait orientations. In this way it lacks the front-facing flexibility of the Twelve South HiRise 3 Deluxe, reviewed further down, but it is available at a significantly lower price and much faster. It comes with a decent-length cable and a 50W USB-C wall charger.
Remember that 25W is only possible for users of the iPhone 16 or 17. Owners of pre-iPhone 16 models can save money by buying the Qi2 15W model ESR 3-in-1 Charger with CryoBoost that’s a little taller but otherwise distinguished only by the 15W maximum speed and a 35W charger compared to the 50W wall charger that ships with the 25W model. In our tests this cheaper Qi2-based CryoBoost 3-in-1 Charger took only 10 minutes longer to charge an iPhone 16 Pro to 50% than the 25W charger. If you can handle waiting that long, you can save some serious money, but those seemingly few minutes do add up over the lifetime of the product.

As with the 2-in-1 model, we are big fans of the Satechi Qi2 Foldable 3-in-1 Wireless Charging Stand.
It has the same small 3.5-inch square (90mm) footprint, and Qi2.2 wireless charging technology to match MagSafe on 25W speed for iPhone 16 and later (older iPhones will charge at 15W). The AirPod charging pad charges at 5W and could instead charge a second phone, although much slower than with the MagSafe pad. Apple Watch charging is fast, with the back-mounted pad providing 5W of power.
It too folds up flat to make it travel friendly, and this time comes with a 45W USB-C chargers that is further boosted with U.K. and E.U. travel adapters. For a 3-in-1, it’s reasonably light at just 14.1oz (399g)—about the same as the cuter and more compact Anker 3-in-1 Cube, reviewed below. If you want a 3-in-1 that fits in your trouser pocket, look to the Kuxiu X40 Turbo, reviewed below in the travel charger section.
It’s not as affordable as ESR’s 15W 3-in-1 Charging Strand ($84.99) so misses our budget recommendation. However, with its foldability and travel plugs, this makes a great charging station choice for at base and on your travels—see lower down for more best MagSafe travel chargers. if you don’t mind the Watch at the back, this charger’s flexibility and fast speeds makes it an easy recommendation.

The fact that it’s heavier than the Satechi 3-in-1 flat pads shouldn’t be a problem unless you are planning to carry it with you as a portable charger—and we think there are much dinkier and suitable travel chargers to choose from. Its extra weight makes this solid desktop stand a more stable base.

The Zens 4-in-1 Modular Charging Station for iPhone, AirPods, Apple Watch and iPad is a MagSafe-certified charging stand made from recycled plastic that can handle not just four Apple devices but more if you buy extra charging modules (up to three at one time) to connect. Any MagSafe iPhone (12-17) can be wirelessly charged at up to 15W, faster than non-certified MagSafe-compatible chargers but not at the possible fastest 25W speed. AirPods and Apple Watch will each charge wirelessly at 5W.
The iPhone can be placed in either portrait or landscape mode. At the back is a stand where you can place an iPad, which can be wired charged via a side-mounted USB-C port at up to 30W. All devices can be charged simultaneously as the power supply has a 65W total output. The Watch module that ships with the 4-in-1 charger can handily be situated on either the right- or left-hand side depending on your preference. Modules attach magnetically. The Apple Watch extension can be disconnected from the main station and charged via a USB-C port to become a standalone wireless charger when traveling.

The 45W power supply also comes with international plug heads for U.S., U.K., E.U. and A.N.Z. There’s also a further USB-C port for input only, but useful if you’d rather not carry the power supply with you on your journey or just want to plug it into an existing multi-port charger at home.

The ESR 3-in-1 Travel Wireless Charging Set is certified by Apple for Apple Watch and Qi2 for 15W iPhone charging. ESR sells a faster 25W model (the 25W CryoBoost Foldable 3-in-1 Magnetic Charging Station, see above) but we rather like this plush 15W Travel Set.
The Watch charging part is separate but plugs in once the stand is unfolded; make sure you don’t lose it, though. When folded the charger can be used as a wireless charging pad. The iPhone can be set in either landscape or portrait orientation when the charger is doubling up as a stand.
It’s lightweight and foldable, which makes it a great travel solution if you own iPhone, AirPods and Apple Watch. The faster Kuxiu X40 Turbo is a more compact package for Apple Watch and iPhone owners because their Watch-charging modules are built-in. The Journey SWIV is about the same weight as the ESR but without the detachable nature of the Watch charger.
It measures 4.5-x-2.6-x-0.63 inches (11.3-x-6.6-x-1.6cm). There’s an optional smart travel case included that fits the charger, cable, Watch attachment and folding charging stand.

The stylish SWIV 3-in-1 iPhone/Watch/AirPods charger folds up extremely neatly into a compact and lightweight package that you wouldn’t really notice in a coat pocket. Of course, despite being wireless when charging your devices it still requires a wall charger (not included); it does comes with a USB-C cable.
The MagSafe charger has been updated to 15W Qi2 but is beaten is speed by the 25W chargers, although the Watch does offer 5W fast-charging for your wearable. The Watch module can lie flat or flip up for Nightstand mode—perfect for a bedside table. If you want a 3-in-1 travel charger with a stand, consider the Kuxiu X40 Turbo, reviewed above.

The Alogic Matrix Ultimate is multi-talented. It can charge an iPhone, Apple Watch and AirPods wireless charging case at the same time, plus you can detach the iPhone charging pad and take it with you as a power bank. You can also detach the Apple Watch charger and slot that into any charging USB-C port, including that on the power bank.
On top of all that, you can fold the whole thing up and pack it in its own carry case.
Fully certified, it boasts 15W wireless iPhone charging, and can fast-charge a Watch at the same time.
The power bank’s battery capacity is 5000mAh, which in our tests gave us nearly a three-quarter recharge. There are alternatives, such as the OneAdaptr OneGo, reviewed above, that feature a 10000mAh power bank with much higher recharge potential—but none are rated as fast at charging as the Matrix Ultimate, which also now comes with international plug adapters (U.S., U.K., E.U., AU/NZ).

Use your iPhone for satnav directions or to have easy access to your playlists in the car with this MagSafe-certified wireless charger and car vent mount, which works in both landscape and portrait modes.
It has an integrated USB-C cable, and a 12V car charger adapter for cars that come with USB-A ports.
The magnetic link is strong, which should mean that it can cope with any big bumps in the road. It works best with straight, horizontal vent slats up to 3mm in thickness and 20mm in depth. It does work with vertical slats, but there might be slight movements if the mount is overloaded with weight, says Belkin.
As a dedicated MagSafe-certified 15W car mount, it is expensive compared to some. If you can handle a lower charger rate, the Belkin BoostCharge Magnetic Wireless Car Charger 10W does pretty much the same job for a lot less. Or you can buy Spigen’s Mag Fit Phone Holder Car Mount and add Apple’s MagSafe Charger (reviewed above) for pretty much the same 15W result. That product is also available in black, like most car vents.

This smart desk mat includes a detachable side strip that includes an adjustable magnetic wireless charging arm for phone and a non-magnetic section to charge your AirPods. Not only is the mat reversible, with smooth, wipeable vegan leather on one side and warmer-feel felt on the other, but you can pull back the mat to stow paper and notes to help reduce clutter. It’s quite a large mat, measuring 28.7 x 14.6 inches (73 x 37cm). The Beige Gray color is actually more of a warm stone tone.
Journey has a range of ALTI charging desk mats but the 15W ALTI Lift is the first to feature a fully rotational flip-up phone stand. The non-Lift basic ALTI—available in four colors—can charge the iPhone only laid flat and at a slower 7.5W. Although costing a little more, we recommend the faster and more adjustable Lift model.
The charging panel connects to the mat with a light magnetic snap, and can be positioned on either side simply by flipping the mat round 180 degrees, depending on whether you are left or right handed. AirPods can be charged at up to 5W. The magnetic fit is strong so you can’t knock it off its charging position with a stray flick of an arm.
Journey
Journey also offers a faster and fancier version of the Alti. The Journey Alti Play offers 15W wireless iPhone charging and cool button-controlled ambient nine-color RGB lighting effects with that will attract gamers or anyone who wants to add some effects to their workspace.
As with the original Alti the magnetic charging panel can be attached to either the right or left side. It does differ in having just one non-reversible side but its fine-weave microfibre lycra cloth surface is designed for a more precise mouse action that will also please gamers. The rubber anti-slip underside keeps the mat firmly in place.
All Alti wireless charging desk mats come with a USB-C cable but require a charger; recommended 30W or higher.

The premium-quality, vegan leather Journey NEXA laptop sleeve bills itself as a “4-in-1”, and it certainly is multi-functional.
As well as protecting your laptop during travel, it includes two wireless chargers (one MagSafe compatible at 7.5W; one 5W for AirPods or a second phone) and can work as both a desk mat and mousepad to free your workspace of clutter.
The most recent NEXA Lift model features an iPhone charger that raises into an adjustable stand.
While it comes with a USB-C cable, you’ll need to add your own charger (check our roundup of the best iPhone chargers) to connect with the USB-C port in the sleeve. Alternatively you can charge the MacBook itself while it sits protected in the sleeve—for this you’ll need a more powerful MacBook charger.
Wireless charging is convenient and fine for situations when you don’t need a super-fast recharge, although the latest 25W wireless chargers are getting close to the power and therefore speed you’ll get from charging via a cable
If you’re leaving your home in 20 minutes and need as much juice as possible, plug in a cable (USB-C for iPhone 15 or later, or Lightning for earlier iPhones) into a USB-C charger (of at least 30W) to power up an iPhone faster than wireless. With 25W wireless chargers you can simply place your iPhone on and know you should be able to charge it to 50% in around 30 minutes.
Wireless charging is less wearing than constantly inserting a cable into your phone, and more reliable as that vulnerable cable port can fill with fluff and dust after all the time spent in your trouser pocket or bag and it’s one of the most common reasons that an iPhone refuses to charge even when connected with a cable. It’s easy to clean with a toothpick (but please do it softly!) but will affect most of us at some time. Read our tips about how to clear dirt and fluff from your iPhone’s charging port.
Wireless charging isn’t affected by the build-up of dust and fluff in the phone port and is also less vulnerable to oxidation and corrosion.
With wireless, you don’t have to remember to run around trying to find who’s taken your charging cable, and it’s certainly a lot neater.
Of course, wireless charging is not really wireless, unless you are using a portable magnetic power bank. The magnetic charger is still connected by a cable to your wall charger; it’s just the connection to the phone that is properly wireless.
What else you need
Some magnetic chargers come with their own wall charger, but most require you to add your own. Apple recommends at least a 20W USB-C power adapter (wall-socket charger) and we agree unless your charger supports 25W wireless charging, in which case go with at least a 30 USB-C charger or higher if it’s a 2-in-1 or 3-in-1 multi-device charger.
An anonymous reader quotes a report from Electrek: A Reddit post making the rounds this week claims the U.S. has experienced at least one major power outage every month of 2026 -- but is it true? I dug into several outages, the extreme weather behind them, and what we can do to help keep the lights on. [...] The claim that hundreds of thousands of Americans were without power over extended periods at least once per month, every month of 2026 surprised be in two ways. First, because I had no idea if it was true -- and, second, because it felt true. We try to do better than writing about things that feel true around here, however, so I did a bit of research (translation: I Googled power outages by month) and came up with the following examples in about sixty seconds
January: More than 296,000 customers still without power as winter storm freezes much of the US
February: More than 380,000 customers without power as winter storm hits US Northeast
March: Storms Cut Power to Over 1 Million Customers in U.S. Midwest, Mid-Atlantic; Ohio Hardest Hit
April: At least 29 tornadoes touched down in Central Illinois on April 17th
May: Energy Secretary Issues Emergency Order to Deploy Backup Generation in the Mid-Atlantic Amid Heatwave
June: More than 373,000 U.S. customers without power due to extreme weather
... and that list is far from comprehensive, and how you feel about it might depend on what you consider a "major" outage, of course -- but consider that there are tens of thousands of Americans without power right now, and that's not making the news. [...] The lesson here is that weather-related grid outages -- whether they're caused by wildfires, mudslides, derechos, tornadoes, ice storms, hurricanes, heat waves, or some other disaster I'm lucky enough to have forgotten about -- read like statistics when they're happening over there, but get personal real quick when they're happening to you.

Researchers on Beaver Island, in Lake Michigan, are trying to find a more reliable form of power using local resources
Beaver Island sits in the middle of the northernmost end of Lake Michigan, about 70 miles from the maritime border with Canada. The forested island, just a little bigger than San Francisco in size, is a popular summer destination for tourists and home to about 600 permanent residents. Getting there requires a boat or plane ride.
Getting electricity to the island is not as easy. Power comes from mainland Michigan through cables that cross roughly 30 miles of lake bed. Outages are common during extreme weather, or when there are problems with the sensitive wires. The devastating ice storm that walloped the state last year knocked out power to the island for weeks.
Welcome to this edition of The Intelligence Brief… This week, a new milestone has been reached in space technology, with the launch of the world’s first satellite equipped with a commercial betavoltaic nuclear power system. The satellite was carried to orbit on a a SpaceX Falcon 9 rocket on Tuesday, and in our analysis, we’ll be looking at 1) how the next generation of compact nuclear power systems are now being tested aboard the first City Labs BOHR satellite, 2) how the satellite converts radioactive decay into electricity, and why this technology could eventually help to facilitate long-term space missions to the Moon and other locales, 3) the advantages and hurdles this novel tritium-based power system faces, and 4) what this all could mean for the future of nuclear powered spacecraft used in deep-space missions.

The First Nuclear-Powered Satellite is Now in Orbit
Tuesday marked a new chapter in the quest for novel power systems for spacecraft, with the launch of the world’s first satellite equipped with a commercial betavoltaic nuclear power system.
The City Labs Betavoltaic Orbital High-Reliability (BOHR) satellite was carried to space on board a SpaceX Falcon 9 rocket, and in the coming weeks will begin tests to determine whether miniature nuclear batteries can reliably generate electricity in space.
Designed primarily as a proof of concept, the first BOHR satellite will rely on conventional solar panels for its primary power system. However, the first-of-its-kind spacecraft also carries the company’s proprietary “NanoTritium” betavoltaic power source, which, according to the company, uses beta particles emitted during the radioactive decay of tritium that are converted into electricity.
In a statement, Peter Cabauy, CEO of City Labs, called this week’s launch “a historic step for commercial nuclear power in space,” adding that the BOHER satellite “demonstrates that safe, compact, and regulatory-approved nuclear power systems are ready for routine commercial deployment.”
“This capability enables persistent, always-on payload operations that are not constrained by sunlight or battery life,” Cabauy added.
Harnessing the Power of Beta Radiation
The innovative satellite was carried to space earlier this week as part of the recent SpaceX Transporter-17 mission.
“On Tuesday, July 7 at 12:12 a.m. PT, Falcon 9 launched the Transporter-17 mission to low-Earth orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California,” read an update that appeared at the SpaceX website announcing the successful launch that carried the City Labs BOHR satellite to space.
“Transporter-17 was a dedicated smallsat rideshare mission,” SpaceX’s update earlier this week added. “There were 81 payloads on this flight, including cubesats, microsats, hosted payloads, and orbital transfer vehicles carrying eight of those payloads to be deployed at a later time.”
Following the satellite’s successful delivery to orbit, its power systems will begin testing the feasibility of beta radiation as a primary driver to produce electricity. In the past, radioisotope thermoelectric generators have been used to propel landmark space missions, such as Voyager 1 and Voyager 2. By contrast, BOHR’s beta radiation system does not rely on heat generated by radioactive decay, which allows for a compact power source that, if all goes according to plan, could one day be deployed in future missions to support spacecraft operating in environments where sunlight is limited. Such applications include the permanently shadowed craters on the Moon and future missions into the outer solar system.
Primarily, City Labs says a tritium-based system is also more beneficial than traditional nuclear fuels like plutonium since it emits relatively low-energy radiation. This, the company says, makes it easier to shield and safer to handle during spacecraft assembly and launch.
Challenges Ahead
The technology does face significant hurdles, however. One involves the fact that tritium is presently still one of the world’s rarest—and most expensive—radioactive materials. Right now, with only around 20 kilograms produced annually throughout the world, the limited quantity and exorbitant costs (current prices reach tens of thousands of dollars per gram) make large-scale adoption anytime in the near term a significant challenge.
There are also regulatory considerations, as noted in a news article released this week by the American Nuclear Society (ANS) following the launch. “In 2019, National Security Presidential Memorandum – 20 (NSPM-20) laid out updates to the process for launching spacecraft containing nuclear systems,” the article states.
“Now the Department of Transportation, which includes the Federal Aviation Administration (FAA), directs the coordination of various agencies to review the safety analysis for missions with nuclear components,” the ANS news brief added, noting that the FAA updated its launch regulations in 2020.
Despite the existence of a few hurdles and other considerations, the mission nonetheless marks an important milestone in the development of next-generation spacecraft power systems. If successful, BOHR could demonstrate that compact betavoltaic power sources are a viable complement to solar energy, opening new possibilities for long-duration missions in some of the darkest and most remote regions of the solar system.
