The Aulumu M10 Multi-Charging Dual-Mag 10000mAh Power Bank is a versatile, space-age portable battery designed to keep all your Apple and other mobile devices topped up simultaneously. Featuring an integrated 35W USB-C cable and dual magnetic charging pads, it’s a sleek, multi-device carry solution that breaks the mold of the typical chunky, black-brick power bank. Its feature set and quirks may be overkill for some, but for those looking for a premium charger with some style, this is definitely worth a look.

Price and what’s included

The AULUMU M10 Multi-Charging Dual-Mag Power Bank is available direct for $90. There are also various bundle options on the same website. In the box is the charger with integrated 160mm (about 6.3 inches) USB-C cable, soft carrying case, and a user manual.

Features and design: Charging with style

The M10 is designed for users who want to reduce cable clutter by consolidating their everyday mobile power backup carry. It stands out with a silver-gray metallic case, an asymmetrical geometric cut design, and a ribbed aluminum alloy body that enhances grip. Unfortunately, the short side grip clicked when I squeezed too hard, making me think some of the mechanical tolerances were slightly off. Overall, its mechanical aesthetic and robotic styling reminds me of classic Robotech.

Thanks to its built-in cable, which doubles as a carrying strap, the power bank features a combination 35W USB-C PD input and output for fast wired charging. It also supports magnetic wireless charging up to 15W (though capped at 7.5W for iPhones). There’s even an integrated Apple Watch charging pad.

With an advanced cooling design that includes conductive silicone, graphene, and dual airflow paths, temperatures are well-managed. A five LED battery indicator shows remaining power, although, as always, I would have preferred a numeric percentage display.

Including the cable, it measures 270mm x 75mm (10.63 x 2.95 inches) and weighs 248g (0.55 lbs). The casing features a glowing light that changes color depending on its charging status, pulsing orange when dispensing power and cool blue when recharging. Other than the ventilation holes and power button, there’s just a single USB-C port. Everything else is just for aesthetics.

Performance: Versatility is the key

The 10,000mAh battery provides a highly reliable backup power source, scoring greater than a 150% total recharge on an iPhone 16 Pro in testing. Using the 35W wired connection, it can also successfully push a depleted 14-inch MacBook Pro to just under 50%.

It’s relatively easy to place a phone or Apple Watch on the respective wireless charging spots as the M10 utilizes strong magnets that keep everything aligned. Perhaps its most compelling feature is its ability to charge up to three devices at once.

You can wirelessly charge a MagSafe iPhone, an Apple Watch, and a third device via the built-in USB-C cable simultaneously. However, it’s important to note that when multiple outputs are active, the power bank caps the total combined output at 15W max. Because the unit manages power sharing under this limit, each connected device will charge slower than if it were plugged in alone. 

Finally, the built-in cable stays securely in place when you use it as a holder/loop, fitting into a secure notch. This means you can easily carry the charger or attach it to a backpack, although I admit to being just a little uneasy doing the latter even with its strong connection. I’m just not sure if putting a cable under that type of stress is the best practice for true longevity, but again, it does seem quite secure.

What about the competition?

The M10 is noticeably longer and bulkier than standard single-device power banks, but it compares favorably against other multi-device solutions. Rival options include the $100 Kuxiu K1 Ultra 3-in-1, which offers faster 25W wireless charging, but lacks an integrated cable. There’s also the $90 OneAdaptr OneGo, which matches the M10’s 7.5W iPhone wireless speeds but also misses out on the built-in cable functionality.

Should you buy the AULUMU M10 Multi-Charging Dual-Mag Power Bank?

The Aulumu M10 is a fantastic option if you want an all-in-one charging solution that looks distinctive and eliminates the need to pack extra cables and Apple Watch pucks. While simultaneous charging speeds drop under heavy load, the sheer convenience and high-quality build make it a recommended addition to your travel bag.

Pros:

• The built-in 35W USB-C cable is bi-directional, fast, and doubles as a convenient carrying lanyard.
• The power bank gives you the ability to charge a MagSafe phone, an Apple Watch, and a third USB-C device simultaneously.
• The premium, asymmetrical metallic design feels intentional and stands out beautifully against standard matte-black alternatives.

Cons:

• The wireless charging speeds max out at 7.5W for iPhones, which is slower than newer 15W or 25W MagSafe-certified competitors.
• The total output drops to a shared 15W max when multiple devices are plugged in, resulting in slower charging times across the board.
• The multi-device features make it slightly larger and bulkier than standard 10,000mAh single-device battery packs.
• My unit’s short side grip clicks when I squeeze the device, making me wonder if the build tolerance is just a bit off.
• The MagSafe Charging Spot is a fingerprint magnet.

Score: 7 (out of 10)
