  • ✅ BESTEK 300W pure sine wave car inverter:Its output waveform is same as the AC power waveform of mains power grid which delivers a smoothly-varying sine wave for sensitive electronics provided by the electric utility.Perfects for off-grid system,Lower THD,Less wear,Strong inductive loads capability.It has little interference with radios, communication and precision equipment.It's also recommended by most cordless tool manufacturer that a pure sine wave inverter is used to ensure long battery life
  • ✅ Two Ways To Connect To Power: This is an inverter converting DC from your car battery to AC for whatever you want to use within its Watt range.It can pull power from the battery through the cigarette lighter plug or directly clamp the alligator battery clips onto the car battery. You can't get 300 watts from a 12-volt cigarette lighter plug, but you can get it by using alligator clips to hold your car battery. If you're going to be plugging this into car cigarette lighter,you should keep the wattage under 150,since that is what most car fuses are set for.
  • ✅ Intelligent Cooling Fan: Unique vents and smart fan design make our 300W power inverter easier to dissipate heat. 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.
