300W Car Power Inverter

300 watt car power inverter

High quality power inverter for car, 600W peak and 300W continuous power, converting 12V or 24V DC battery power to 110V or 220V AC power, output modified sine wave, with multi-safety protections against overvoltage, undervoltage, overload, overheat and reverse polarity connect, AC outlet and USB charging port for powering devices such as cell phones, laptops, tablets, etc.


  • 300 Watt continuous and 600 Watt peak power
  • 110V or 220V AC household power outlet – power AC electronic devices in your vehicle
  • USB port – charge your smartphones, laptops, tablets and other USB-powered devices
  • Multiple safety protection – overvoltage, undervoltage, overload, over temperature, short circuit protection (reverse polarity connect)
  • Compact design, easy to use and high efficiency – ideal for use on road trips, vacations, work trips, camping and other outdoor activities where AC power is needed
