Feature:1. [1000W Power And USB Port] The pure sine wave inverter provides 3000W and dual AC outlets with continuous DC to AC power output, 5V 2.1A USB port, and the USB port can charge most phones and tablets.2. [Multi Protection] The off grid inverter uses isolated input and output technology with protection for overload, low voltage, high voltage, overheating and short circuit for improved safety.3. [Cooling Fan] Our off grid inverter has a cooling fan to prevent the device from overheating. With stepless variable speed and temperature control settings, the fan speed is determined according to the heat generated by the machine's operation and runs silently.4. [Aluminum Alloy Housing And Multi Vent Design] The pure sine wave inverter has a heat dissipating aluminum alloy housing and multi vent design with red copper material, which converts higher power.5. [Wide Application] The pure sine wave inverter can supply power to small devices such as laptops, tablets, printers or any other household appliances, either inductive load or resistive load appliances, widely used for home appliances, cars, industrial, office, travel, etc.Specification:Item Type: Pure Sine Wave InverterMaterial: Aluminum Alloy, Red CopperOutput Power: 1000WPeaking Power: 2000WDisplay: LCDOutput Waveform: Pure Sine WaveInput Voltage (DC): 12VUSB: DC5V 2.1AOutput Frequency: 50Hz Or 60HzOperating Temperature Range (Rated): 32F-104F/0C-40CLow Battery Alarm Range (Rated): 10-10.4VLow Battery Shutdown Range: 9.7-10VHigh Battery Shutdown Range: 15V.Package List:1 x Pure Sine Wave Inverter2 x Battery Cable1 x Power Cord1 x Instruction Manual
