Is 30W enough to charge a laptop?

Only for small, low-power laptops and slowly. Most full-size laptops want 45W or more over USB-C, and 30W may not keep one charged under load.

Does it work in Europe?

Yes. The 12-230V input covers European 230V outlets, but you will need a plug adapter for the local socket.

How many devices can it charge at once?

One. It has a single USB-C port, so phones, tablets and other devices share the 30W one at a time.

The listed specs mention only the charger and its power connection, not a USB-C cable. Plan on supplying your own.

Is $16.99 a good price?

It is a low price for a 30W GaN charger, and Best Buy is the only store listing it new as of November 7, 2026. There is little price history to compare against.

Will it fast-charge an iPhone or Samsung phone?

It can deliver up to 30W over USB-C, which is enough for fast charging on most recent iPhones and Galaxy phones when paired with a suitable cable.

Our take on the Greenworks 30W USB-C GaN II Charger

A compact 30W wall charger from Greenworks that uses GaN II technology to keep the brick small while delivering up to 30W over USB-C. It accepts 12-230V input, so it works on US and European outlets with a plug adapter. At $16.99 at Best Buy as of November 7, 2026, it is a low-cost single-port charger, and only one store currently lists it new.
