According to Ugreen, the new model is roughly 58% smaller by volume than its previous 45W chargers, thanks to GaN technology.
The flat, rectangular charger features foldable prongs and a single USB-C port on the bottom edge. It comes in a silver-gray finish.
The 45W output is sufficient to fast-charge modern smartphones, tablets, and handheld gaming PCs.
