Magnetic battery packs are convenient, but the 10,000mAh models usually come with a clear downside: they add a lot of bulk to your phone. Anker is trying to address that with its new Air+ Ultra Slim Magnetic Power Bank (Nano), which recently went on presale in China for 399 yuan ($58).
Anker Air+ Ultra Slim Magnetic Power Bank Specs
The focus of this new battery pack is keeping the physical footprint down while maintaining a standard 10,000mAh (39.2Wh) capacity. It measures 1.47cm thick and weighs about 210 grams. While it’s not weightless, it is thinner than most standard magnetic power banks in this capacity range.
Anker designed the dimensions so it fits properly on the back of supported iPhones, meaning it shouldn’t block the camera bump or stick out past the bottom edge of the device. It attaches using 17 built-in rubidium magnets, which provide a 12.8N magnetic force. It will also work through magnetic phone cases, provided they are under 1mm thick.
For charging, the specs are solid and practical. If you use it wirelessly, it outputs up to 15W for compatible iPhones. According to Anker, that will get an iPhone 17 Pro to about 40% in 30 minutes.
If you need to charge faster, there is a USB-C port that supports up to 30W for both charging your phone and recharging the battery pack itself. Using a cable, an iPhone 17 Pro can reach 50% in around 22 minutes.
The power bank uses ATL battery cells, which is the same supplier Apple uses for its devices. To keep things from getting too warm during use, the internal structure includes high-polymer graphene materials and a dedicated temperature control chip. Interestingly, you can also connect the power bank to Anker’s companion app to monitor the battery’s health and check its real-time temperature.
On the safety side, the device meets China’s 2026 safety standards, passing tests for puncture resistance, compression, and heat exposure. It has a soft-touch finish with metallic accents and comes in four colors: Black, White, Blue, and Orange.
In related news, Ugreen has introduced a new 45W 10,000mAh power bank with a built-in PD3.0 USB-C cable, while OnePlus recently launched a 15,000mAh 120W power bank featuring enhanced battery safety technology.
