Features Professional Made: This power inverter can convert 12V DC input to AC output, and the conversion is efficient and stable. Better Designs: Using power control chip design, SMT chip technology, patented voltage stabilization technology, etc. Reliable Performance: The power inverter also offers protection against battery under voltage, battery over voltage, output overload and so on. Practical Function: The power inverter able to provide safe and reliable AC power for household appliance such as TV, video player and tool. Fine Workmanship: The aluminium alloy casing is very sturdy, which enables good durability with oxidation and long using. Specification: Item Type: Power Inverter Material: Aluminium Alloy Input: DC 12V USB Output: 5V 2A Under Voltage Alarm: 9.5-11V Low Voltage Shut Down: 9-10.5V Over Voltage Shut Down: 14.5-15.5V No Load Current: <0.3A Conversion Efficiency: 80% Over Temperature Shut Down: 60℃±5% Note:  1. when TVs, monitors, electric motors, electric drills, large refrigerators, air conditioners, etc. get to the peak power at startup. Although the converter can withstand peak power twice the nominal power, the peak power of some appliances that meet the requirements may exceed the peak power, trigger overload protection and cut off the current, and this may happen when driving multiple electrical appliances. At this time, the electrical switch should be turned off first, the converter switch should be switched, and then the electrical switches should be turned on one by one, and the electrical appliance with the highest peak power should be turned on first.  2. During use, the battery voltage begins to drop when the voltage at the 12VDC input terminal of the converter drops to 9.5-11.0V, the electricity and other sensitive electrical appliances should be turned off in time. When the voltage of the 12VDC input terminal drops 9.0-10.5V, it will automatically shut down, which can prevent the battery from being over discharged. After the power protection is turned off, the red indicator light is on, the vehicle should be started in time, and the battery should be charged to prevent power failure, which will affect the start of the car and the life of the battery.    Package List: 1 x Power Inverter 1 x Crocodile Clip Cable 1 x Cigarette Lighter Wire 1 x User Manual   Package List 1 x Power Inverter 1 x Crocodile Clip Cable 1 x Cigarette Lighter Wire 1 x User Manual
