However, the GPD Win 2 makes a sort of hissing noise if it's connected at full charge. It doesn't seem to be having any adverse effects though.

This one looks decent with some extra ports

Doesn't plug directly into the wall, it's a bit too big for that

Has been reviewed by Benson and tech journalists very well and is USB certified
