ETL Listed, BESTEK 300Watt Pure Sine Wave Power Inverter DC 12V to AC 110V Car Plug Inverter Adapter Power Converter with 4.2A Dual USB Charging Ports and 2 AC Outlets Car Charger

#ad
BESTEK #ad - Isolated voltage protects perfectly for your device from over-voltage, under-voltage, reverse polarity, overheat, Overload, 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. 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, Strong inductive loads capability. It has little interference with radios, Less wear, 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.

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. Plug this into 12v cigarette lighter outlet provides continuous DC to AC power with 2 AC outlets operates any 110v device and 2 USB ports which detects your device automatically to deliver its fastest charge speed up to 2. 4 amps per port/4.
