Anker Nano Power Bank review

Anker's Nano Power Bank is among the first Qi2 certified models and is evaluated for size, speed and everyday usability.

Anker Nano Power Bank tests Qi2 potential

The Anker Nano Power Bank is compact (122 grams, 8.6 mm thick) and holds a 5000 mAh battery. It supports up to 15W wireless charging and offers a USB-C input that can also charge another device. Built with a metal chassis and a graphene heat-dissipation layer, it uses magnets that align well with MagSafe compatible phones and shows four LEDs to indicate remaining charge. In testing with an iPhone 16 Pro Max from 50% battery, it added 15% in just over 30 minutes and reached 80% in about 1 hour and 20 minutes; Anker notes charging to 100% may pause due to software limits.

The unit is designed for quick top-ups rather than full recharges, making it most useful for daily use rather than weekend trips. It can also wirelessly charge compatible earbuds and is advertised at $55 in the US ( £50 in the UK). While it’s best paired with Qi2 devices today, the open standard points to broader adoption as more models arrive, including future Pixel and other Android phones.

The Nano Power Bank highlights a shift toward pocketable charging that matches MagSafe fashion with practical magnetic alignment. Qi2 aims to standardize wireless power across devices, but adoption is still early, and consumer confidence will hinge on compatibility across brands. For consumers, the key question is whether a small pack can meaningfully replace larger power banks in day-to-day life or simply serve as a reliable top-up tool as ecosystems evolve.

From a market view, Anker’s pricing and the device’s compact form factor place it as a gateway product for Qi2. If more mainstream phones integrate Qi2 magnets and faster top-ups, the category could grow quickly. Yet the real test will be the breadth of compatible devices and the consistency of charging speeds across brands.

Highlights

As Qi2 devices expand, pocket charging could become a more common daily habit.
