500W continuous and 1000W surge power inverter converts 12V DC battery power to 120V/220V AC household power. With full safety protections against over voltage, under voltage, over load, over temperature, short circuit and reverse connection, this is a best inverter for car or home use, ideal for powering mobile phone, laptop, iPad, kindle, digital camera, fan, light, etc., on road trips, vacations, camping or anywhere DC to AC inverter is needed.
Note: Refrigerator or similar to the refrigerator load equipment, need to choose 10 times more power inverter.

Power Inverter Applications

Tips: What can be regarded as an excellent power inverter?
Power inverter is a device that can convert 12V/24V/48V DC energy from car battery or battery bank into 110V/120V/220V/230V/240V AC power to run the electronics, appliances or various power tools. An excellent power inverter should meet the requirements as below.
- Good ventilation, heat dissipation, workmanship and electronic components.
- Provide enough power output interfaces and types of interfaces.
- High conversion efficiency and clear product power identification.
- Provide all kinds of intelligent protections.
