Looking like something from a spaceship, the Aulumu M10 Power Bank will draw admiring glances, and envious ones too if the starer’s Apple devices are running low on battery.

Design

The Aulumu M10 Multi-Charging Dual-Mag 10000mAh Power Bank has a long name and a long body compared to most magnetic power banks. This is because, as its name suggests, it’s not just good at recharging a connected iPhone but will work with other Apple devices too—even at the same time.

You could wirelessly charge an iPhone (12 and later) plus any model of Apple Watch, while using the built-in cable to charge a third USB-C device. That could be your AirPods case if it has USB-C as its charging port rather than the older Lightning port.

The M10 measures 5.3 inches (135mm) long by 2.9 inches (73mm) wide and 0.7-inch (18mm) deep, and weighs 8.7oz (248g). Compared to other 10K power banks it’s bulky but remember this beast can charge three devices at once—two wirelessly.

It’s better compared to similar multi-device battery packs. Rival magnetic iPhone and Apple Watch-charging power banks include the 10K Kuxiu K1 that measures 4.1 x 2.7 x 0.8 inches (105 x 69 x 20mm) and weighs 8.9oz (253g). The OneAdaptr OneGo has dimensions of 4.7 x 2.8 x 0.94 inches (120 x 70 x 24mm) and a weight of 7.8oz (220g).

The M10 is noticeably longer than both those alternatives but about the same width a little slimmer, with around the same weight.

The silver-gray metallic case looks cool, as do the five indicator LEDs and the glowing light that changes color depending on what it’s doing. When charging, it pulses orange. When being charged itself, it’s more of a cool blue.

The 6.3-inch (160mm) USB-C cable means you won’t have to carry around a spare cable if you want to charge faster using a wired connection. It fits into a secure notch making it a handy carry cable that you can hold or attach to another object such as your belt to backpack.

The battery-life indicator is made up of five easily visible LEDs, compared to the usual four. The more LEDs the more accurate picture you have of how much power is left in the battery pack. For a four-LED display each represents 25% so is only accurate to that degree, The M10’s five mean you know within 20% what the remaining charge is. A digital display—seen with some power banks such as the Kuxiu S3—gives the most accurate reading down to a single-figure percentage.

Old-school wireless speeds

While the look is futuristic the charging speeds are a bit yesterday, so space-age in a retro rather than futuristic way.

While some magnetic power banks are now rated at 25W charging power (Qi2.2), the Aulumu M10 is “MagSafe Compatible” so only 7.5W compared to the now normal 15W certified-MagSafe or Qi2. In its specs it claims a 15W maximum but for iPhones an uncertified rating means it will drop to 7.5W. We’d expect 15W as a minimum these days, but that elevel of power/speed is important only if you are in a real hurry.

The low power output means it will take longer to charge an iPhone: around 90 minutes compared to 15W’s 45 minutes or 25W’s approximate 30 minutes.

If you’re not in a rush, this doesn’t matter at all, but if you need to quickly recharge your iPhone look at our other best magnetic iPhone power bank reviews—or use the 35W USB-C cable direct to the iPhone (if iPhone 15 or later) as shown above. Wired charging beats even 25W wireless and is certainly speedier than 7.5W wireless.

The Apple Watch charger on the other side is rated at 2.5W, so won’t fast-charge your Watch like some of the best Apple Watch chargers that can output 5W to the Watch.

When using all three outputs—wireless iPhone and Watch plus cable—at the same time, total output is 15W.

Performance

The Aulumu M10 has a 10000mAh (milliamp) battery, rated at 36Wh (watt hours).

In our tests using an iPhone 16 Pro, it scored 158%—meaning it completely recharged the depleted iPhone once and then again to 58% on the second charge once the iPhone had run dry again.

Compared to other 10K magnetic power banks this score is not the lowest (around 140%) but also not the highest (190%), with the average being about 170%.

That said, those are iPhone-only power banks without the added Apple Watch-charging module. Anyone whose Watch has died during the day will thank themselves for buying a dual-device power bank when it’s needed, rather than carrying an individual Apple Watch power bank or just losing all those Activity points while out and about.

Using the 35W cable we recharged a spent 14-inch MacBook Pro to 45%, which is about the average for a 10K power bank—and again a useful tool for any tech traveler.

Price

The Aulumu M10 Multi-Charging Dual-Mag 10000mAh Power Bank is priced at $89.98 / £79.

Rival multi-device power banks include the $99 Kuxiu K1 Ultra 3-in-1 MagSafe 10K Power Bank, which is faster at 25W but lacks the M10’s integrated cable, and the equally cableless $89 OneAdaptr OneGo 3-in-1 power bank (also 7.5W).

Should you buy the Aulumu M10 Multi-Charging Dual-Mag 10000mAh Power Bank?

We love this 3-in-1 power bank’s amazing looks and built-in cable, but the low wireless power output rather lets this multi-device power bank down if your charging needs are immediate.
