Feature: 1. 800W High Power: The pure sine wave inverter provides dual AC outlets with continuous DC to AC power output, 5V 2.1A USB port, and the USB port can charge most cell phones and tablets. 2. Isolated Input and Output Technology: 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. Excellent Heat Dissipation: 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 Red Copper: 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. Suitable Scenario: 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 Inverter Material: Aluminum Alloy, Red Copper Output Power: 800W Peaking Power: 1600W Display: LCD Output Waveform: Pure Sine Wave Input Voltage (DC): 24V USB: DC5V 2.1A Output Frequency: 50Hz Or 60Hz Operating Temperature Range (Rated): 32°F-104°F/0°C-40°C Low Battery Alarm Range (Rated): 20-121V Low Battery Shutdown Range: 19.4-120V High Battery Shutdown Range: 30V.
