Xiaomi has unveiled one of the slimmest magnetic power banks we’ve seen, measuring just 6mm thick and weighing 98g.
The new Xiaomi UltraThin Magnetic Power Bank 5000 15W is designed to snap onto compatible smartphones. At the same time, it remains barely noticeable in your pocket.
Despite its card-like profile, the power bank packs a 5,000mAh battery. Xiaomi uses a high energy-density silicon-carbon cell with 16% silicon content, alongside a large graphite cooling sheet. This helps keep the design thin without sacrificing everyday usability. It’s small enough to sit flush against the back of a phone. Yet it is substantial enough to provide a meaningful top-up.
Wireless charging tops out at 15W, though iPhone models support up to 7.5W magnetic charging. There’s also 22.5W wired charging via USB-C, giving users a faster option when needed. Xiaomi says wired use can extend the music playback time of its latest Xiaomi 17 handset by roughly nine hours. The power bank can also charge two devices simultaneously, and even continue powering devices while it recharges itself.
Compatibility covers a broad range of devices, including Xiaomi’s recent flagship models. It also supports the iPhone 12 through the iPhone 17 series. Furthermore, select Samsung Galaxy Ultra handsets are supported. Google Pixel devices, including the Pixel 9 and Pixel 10 lines, are included as well.
Design is clearly part of the appeal. The aluminium alloy shell features a subtle metallic finish and rounded edges. Additionally, it has a photolithographically etched logo. Xiaomi has also added a fibreglass surface layer with a heat-resistant coating. Along with that, dual NTC temperature controls help regulate heat during charging.
Ultra-thin magnetic battery packs aren’t new, but Xiaomi’s 6mm approach pushes portability further than most.
