“Excellent, robust charger with a nice carrying handle. You can select the percent of charge to be 80%, 90%, or 100% and the current to be 2, 4, 5, 6, or 7 Amps. My King Song S22 Pro’s battery went from 8% to 100% in about 2 hours and 21 minutes with the amperage setting at 7A. Even while charging at maximum current (7A), the metal housing got only became a little warm. (My original charger was hot to the touch). I plan on charging at the lowest amperage in the future, but it’s nice to know that I can go from a dead battery to fully charged in less than an hour and a half. The fancy display shows the realtime charging current and voltage, and lets you know when the EUC is fully charged.”
