Please noted that the built-in fan would do starts run very slowly once flipped the ON/OFF switch to ON, even though under no loads. The fan has 4 gears of rotating speed can be self-adjusted by temperature and power loaded increasingly. This running fan slowly means the inverter is working normally because this new design is to avoid misunderstanding by some buyer's thoughts the inverter is not working or defective if the fan is not running or very quiet when powered and under no any loads.
  • ✅ Intelligent Protection System: Isolated voltage protects perfectly for your device from over-voltage, undervoltage, overheat, overload, reverse polarity, short circuit. It will not drain your battery dry because of an under-voltage protection point. The Inverter does automatically sense overload condition and shuts down AC power when the load exceeds 300W.You will need to power Off/On to reset the overload condition indicated by the Flashing Red.The ON-OFF switch only works for the 3-prong plugs.
