UGREEN 20W 30W GaN Charger PD Fast USB Type C Charger USB C PD3.0 QC3.0 Quick Charging For iPhone 15 14 13 Mobile Phone Charger
Computer Peripherals
“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.”

Larger physical size and lower power-to-volume ratio versus some 30W nano competitors
denkiotaku (YouTube)when you compare them closely you can see that their sizes are quite different

Appears to lack PPS (programmable power supply) capability for fine-grained voltage control
