Features HIGH PRECISION CIRCUIT BOARD - High precision circuit board adopts fine workmanship, provides clear wiring, good quality current and longer service life. MULTIPLE PROTECTION: Comes with over-voltage protection (high voltage cut-off is a kind of protection against high voltage), overload, under voltage, over-current, short circuit and over temperature. REVERSE CONNECTION PROTECTION - DC 5V USB output, the output waveform is a modified sine wave and the fuse provides reverse connection protection, which is safe. INDEPENDENT POWER SWITCH DESIGN: Independent power switch design possesses stable performance, reduces power consumption, and extends machine life. QUIET FAN HEAT DISSIPATION: Quiet fan heat dissipation with fast heat conduction evacuation, no heat and more peace of mind. Specification: Item Type: Car Inverter Product material: aluminum alloy Continuous Power: 1000W Maximum power: 2000W. USB output: DC 5V Output waveform: modified sine wave Reverse Connection Protection: Fuse Protection: over voltage (high voltage cut-off is a kind of high voltage protection), overload, low voltage, over-current, short circuit, over temperature Package List: 1 x Inverter 1 x Cigarette Lighter 2 x Wire Clamp 1 x User Manual Small Note: Pay attention to electrical safety.
