Feature:1. HIGH POWER OUTPUT: This 500W power inverter provides continuous power output and a surge capacity of up to 1000W. Converts 12V DC battery power to a standard 220V AC outlet for use with larger devices.2. PURE SINE WAVE OUTPUT: The pure sine wave output ensures that even the most sensitive electronic devices operate smoothly and without any issues or interference.3. MULTIPLE OUTLETS: Comes equipped with one universal AC220V outlet and two USB ports for powering up laptops, tablets, and other household appliances that less than 500W of power.4. MULTIPLE PROTECTIONS: Made with sturdy aluminum alloy shell, this inverter features built in fuse, cooling fan, and protection against overload, undervoltage, overvoltage, overheating, and short circuit.5. SMART COOLING FAN: The intelligent cooling fan is almost silent and automatically speeds up as the temperature rises, preventing the inverter from overheating and ensuring its longevity.Specification:Item Type: Power InverterMaterial: Aluminum Alloy, ABSStandard Input Voltage: DC12VInput High Voltage Protection: DC15.8VInput Low Voltage Protection: DC9.5V (low voltage alarm 10.20.5VDC)Output Voltage Range: AC220V6VFrequency: 50HzInverter Efficiency: 93%Output Waveform: Pure sine waveFunction Parameters: Current limit, hard soft start, input reverse protection, short circuit protection, input high and low voltage protection, low voltage alarm, over temperature protection, overload protection, power temperature controlled fan (when the power reaches 100 to 200W or when the temperature is 45, the fan will rotate)Fan Type: Sealing OilProtection Automatic Recovery: ManualInput Terminal Wiring Method: Terminal postOutput Interface: International universal socket x 1, USB x 2Average Power: 500WPeak Power: 1000W.Package List:1 x Power Inverter1 x User Manual2 x Crocodile Clip Cable1 x Car Charger
