Anker 511 Charger (Nano 3) 30W USB-C GaN — A2147

Anker 511 Charger (Nano 3) 30W USB-C GaN

Thirty watts in something roughly the size of a large sugar cube, weighing 36 grams. This is what gallium nitride was invented to make possible. See the alternatives in chargers and adapters.

Why GaN makes it this small

Gallium nitride switches faster and wastes less energy as heat than the silicon inside a conventional charger. Less waste heat means less material is needed to shed it, which is how Anker fits 30W into something about seventy per cent smaller than a standard 30W adapter. Running cooler is the part that matters in daily use, particularly if it lives permanently in a wall socket beside a bed.

What it will charge

The output profiles run 5V/3A, 9V/3A, 15V/2A and 20V/1.5A. That last one is the interesting figure: 20V is a laptop charging voltage, so this will run many USB-C laptops including a MacBook Air, not just phones. PPS covers 3.3–11V at up to 3A, which is the range Samsung's Super Fast Charging needs, so Galaxy phones charge at full speed rather than falling back. ActiveShield 2.0 monitors temperature continuously and throttles output if it climbs.

The cable is not included

Worth knowing before you order. You will need your own USB-C cable, and the cable determines what you actually get: for Samsung Super Fast Charging it must be rated 5A, and for an iPhone you need USB-C to Lightning or USB-C to USB-C depending on the model. Our cables and converters section covers both.
