Anker Air+ Ultra Slim: 10,000mAh in 15mm that won't block your iPhone camera

Anker has launched the Air+ Ultra Slim Magnetic Power Bank in China, packing 10,000mAh into a 15mm-thin shell that weighs 210g. The presale price is 399 yuan (around $58), and the design specifically avoids blocking the iPhone's camera module—a small but real frustration that anyone who shoots video while charging will recognize. There's no US or UK release date yet.

The design

At 15mm thick, the Air+ Ultra Slim sits flush against the back of an iPhone without covering the camera bump or hanging over the bottom edge. That form factor matters if you want to keep shooting or scrolling while the battery tops up. For comparison, Anker's own Nano 5K MagSafe power banks—the ones currently selling in the US and UK for around $59.99—are thinner but hold half the energy. The Air+ doubles that capacity without becoming a brick.

The specs

Wireless charging runs at 15W via 17 neodymium magnets rated at 12.8N of pull force—strong enough to hold through cases up to 1mm thick. Anker claims an iPhone 17 Pro reaches 40% in 30 minutes wirelessly, or 50% in 22 minutes over the USB-C port, which outputs 30W. That same USB-C port handles recharging the power bank itself. The cells inside come from ATL, the same supplier that makes batteries for Apple devices, according to Gizmochina.

Heat is managed through graphene materials and a dedicated temperature chip. A companion app lets you monitor charge level and real-time temperature—useful for wireless charging, which tends to run warm.

Worth waiting for?

The 30W wired output is mid-range rather than class-leading. Rivals already shipping globally include the Ugreen 45W and Baseus Qi2 25W wireless models, and Notebookcheck notes that the Air+'s 15W wireless falls short of the newer Qi2.2 standard's 25W ceiling. If Anker brings the Air+ to Western markets, it would likely land at $80–100—a noticeable step up from the Nano 5K. Whether double the capacity justifies double the price depends on how often you drain your phone before reaching a wall outlet. For now, it remains a China-only presale with no confirmed timeline for a US or UK launch.
