Anker Nano 30W USB-C GaN Charger review
A pocket-sized 30W charger using GaN technology to pack fast charging into a noticeably smaller form factor.
Quick take
By using Gallium Nitride (GaN) instead of silicon, this charger fits 30W of output into a noticeably smaller size than a typical wall charger. It delivers full-speed 30W charging for compatible phones and tablets, and Anker's temperature-monitoring safety technology checks in roughly 3 million times a day — twice the frequency of the standard ActiveShield system.
From our own use
I own this 30-watt Anker charger and keep it in my laptop bag. It is compact, charges quickly, and offers the quality I expect from Anker at a reasonable price.
