4. Operating Instructions
4.1 Using AC Outlets
Once the green indicator light is on, you can plug your 110V devices into the three AC outlets. Ensure your devices are mechanical controlled (with a physical ON/OFF button) and within the 26-2300W power range.
4.2 Using USB Ports
The converter features 2 standard USB ports, 1 QC 3.0 port, and 1 Type-C port. You can charge up to 7 devices simultaneously (3 AC + 4 USB). For USB charging only, it is not necessary to turn on the AC part of the converter; simply plug in your USB devices.
