Simultaneously charge 4 devices at full speed and save up to 1 hour of charging time with UGREEN 100W usb c charger. All ports support QC (quick charge) agreement. Only one charger meets all your charging needs. Less Heating and Higher Charging EfficiencyOne of core factors of affecting power efficiency is the heat-dissipating capability. The third generation gallium nitride (GaN) semiconductor helps the charger to generate less heat and fasten the heat-dissipating process. At the meantime this charger provides double power density and reduces power losses by 80% which also means increases the power efficiency. Accurate Intelligent Power DistributionUGREEN 100W 3C1A GaN Fast Charger is nicely designed to support most of the fast-charging protocols to ensure that your device is charging at the fastest safe speed.
