describe: The inverter has a built-in independent cooling fan, an additional USB charging port, and has ambient lights on both sides, which can be connected to a variety of devices. The LED display will show the input voltage and output voltage of the battery. The power inverter comes with a free cigarette lighter and 2 battery clips, providing 300W/600W/1000W/2000W/2500W continuous power, 600W/1200W/2000W/4000W/5000W peak power (please ensure that the total power rating of the connected devices does not exceed the peak power). [Modified sine wave output] The AC modified sine wave output has little interference, low noise and high load capacity, which will not affect the service life of the equipment Quick ChargeCar inverter with intelligent digital display, 4 USB ports and power sockets, suitable for mobile phones, computers, laptops, breast pumps, atomizers, shavers, medical rescue equipment, emergency equipment, etc. Multiple ProtectionBuilt-in fuse can protect your device. Safe charging design prevents "+" "-" reverse connection, overheating, undervoltage and overvoltage, short circuit, overload and overcharge Wide UseLightweight and compact, ideal for vacation, camping and business travel. It can connect to almost any 12V ~72V car battery and provide charging needs anywhere Specification: Colour: Red Waveform: Modified Sine Wave Input voltage: 12V/ 24V / 36V / 48V / 60V / 72V Output voltage: 110V/220V Rated power: 300W/600W/1000W/2000W/2500W Peak power: 600W/1200W/2000W/4000W/5000W Input voltage range: 9.5 V~75.5 V Output voltage range: 110 V/220 V5% Working temperature: 0~40 Frequency: 50Hz/60Hz Effect: > 90% Circuit topology: push-pull No-load current: 0.7A Minimum protection voltage: 12V2V Maximum protection voltage: 72V2V Over temperature protection: 55~77 Overload Protection: Yes Low Voltage Protection: Yes High Voltage Protection: Yes Output short circuit protection: yes Positive and negative reverse link protection: yes
