Detailed overview: Anker Nano 3 30W GaN mains charger

The Anker Nano 3 (511) charger is a 30W USB-C wall brick that has made compactness its headline feature. Thanks to GaN (gallium nitride) technology, Anker drastically shrinks the electronics: the Nano 3 is up to 70% more compact than a standard charger of equivalent power, while delivering the same energy. The body stays compact enough to slip into a bag or pocket without snagging.

On performance, it relies on Anker's own PowerIQ 3.0 with PPS technology. In practice, it recharges an iPhone up to 3 times faster than a stock 5V charger, and handles fast charging of Samsung Galaxy (PPS compatible), Google Pixel, iPad, AirPods and other USB-C devices. Its 30W is enough to quickly charge most smartphones and even top up a tablet or a small laptop.

The ultra-compact format makes it the ideal travel charger: it slips into a pouch or bag pocket, and neatly replaces the bulky stock brick. The brand includes its usual protections against over-voltage and overheating, for safe charging.

Note: the cable is not included, so you need a USB-C cable suited to your device (USB-C to USB-C, or USB-C to Lightning for older iPhones). For anyone after a fast, reliable and tiny charger, the Nano 3 is a sure bet.

Our tester's review: Christophe Delpuech

See our tester's profile

We put the Nano 3 (511) through its paces on several devices, and it holds up to its 30W claim: an iPhone 14 Pro pulls around 20W, a Pixel 7 around 18.7W, and even a MacBook Air picks up close to 26.5W for a quick top-up. Thermal behaviour stays steady too, the case settles around 71 °C under sustained full-power use with no drift. One thing to flag before you buy: the folding plug you may have seen mentioned only ships on the US version, ours has fixed prongs, still compact but not the flip-away design. The safety margin before the charger cuts out under overcurrent also felt a touch tight on our unit. Cable is not included and there is only one port, so it is a one-device-at-a-time charger. For a small, fast, dependable everyday brick, it remains a safe bet.
