UGREEN's GaN charger combines a gallium nitride power semiconductor and USB Power Delivery (PD3.0) / Quick Charge (QC3.0) protocol support in a compact, travel-friendly body with a foldable plug. It's a solid, pocketable 20–30W PD charger that reliably negotiates 9V fast charging for modern phones, but it is larger and less power-density optimized than some competing 30W GaN nano chargers and appears to lack PPS voltage-stepping for precise laptop/camera charging.
Buy if you want a compact, GaN-based 20–30W USB-C charger with PD/QC support for phones; avoid if you need the smallest nano profile or PPS for precise device charging.
