Anker 511 Charger Nano 3 30W GaN USB-C Foldable

Compact 30W GaN Charger

The Anker 511 Nano 3 delivers 30W of power through a single USB-C port in a housing that measures 1.12 inches thick. It replaces a conventional 30W brick with a unit roughly 70% smaller, making it practical for phones, tablets and a MacBook Air. The foldable plug keeps the profile slim inside a bag or pocket. It suits travellers and desk users who want one charger for several devices.

Thermals and Efficiency

ActiveShield 2.0 monitors temperature over three million times per day, doubling the check rate of the previous version. The GaN semiconductor runs cooler than silicon equivalents at the same output, so surface temperature stays low during typical phone or tablet charging. No fan is present, so operation is silent. Power draw at the wall matches the connected device's demand up to the 30W ceiling.

Sustained Load Behaviour

When a laptop such as a MacBook Air draws the full 30W continuously, the charger maintains output without throttling in normal ambient conditions. The protection circuit will reduce power only if internal temperature exceeds its safety limit. An iPad Air (5th Generation) reaches 50% charge in 45 minutes, showing that the 30W rate is held for the bulk of the cycle. The single port means simultaneous high-power charging of two devices is not possible.
