This UGREEN GaN charger fits travel and daily carry when one adapter must serve several USB-C devices and an occasional USB-A peripheral. Evidence confirms 100 W total power, four ports, USB Power Delivery 3.1, PPS, weeks of reliable desk use, and a 226.796 g weight. Connecting several devices redistributes power, can reduce laptop charging speed, and may make the charger warm.
