Selling point:_x000D_ 1. [4000W power inverter] Automobile power inverter, with 2 USB ports and AC sockets. The power inverter is equipped with a free cigarette lighter and 2 battery clips, providing 300 W continuous power and 4000 W peak power (please ensure that the total rated power of the connected equipment is 300 W)._x000D_ 2. [LED green and red work lights] When the inverter works normally, the green LED lights work and tell you that it works normally, but when it is in a protection state, such as low voltage, high voltage, over temperature or overload, the red LED lights up. You need to turn off the inverter, check which protection function is normal, and try to solve it, then the inverter can work again._x000D_ 3. [LED screen display] LED screen displays battery input voltage and output voltage. The cigarette lighter cable can conveniently power the equipment. If the output power is higher than 150W, use alligator clips to connect the battery._x000D_ 4. [Fast charging dual USB ports] One AC socket and two USB ports can provide 100% fast charging for mobile phones, computers, laptops, breast pumps, atomizers, razors, medical rescue equipment, emergency equipment, etc., which can be used as emergency power supply_x000D_ 5. [Multiple protection] The built-in fuse, safe charging design and cooling fan can prevent the automobile power converter from overheating, thus saving power and energy. Protection against overvoltage, overload, overcurrent, short circuit, undervoltage, overheating and short circuit._x000D_ 6. [Lightweight design and top quality] Lightweight and compact, it is very suitable for vacation, camping and work travel. It can be plugged into almost any 12V power output vehicle to provide charging opportunities anywhere. _x000D_ Specifications:_x000D_ Name: Automobile power inverter_x000D_ Input voltage: DC 10.5V~15V,_x000D_ (When the battery voltage is lower than 10.5V, the inverter is under low voltage protection; when the battery voltage is higher than 15V, the inverter is under high voltage protection)_x000D_ Output voltage: AC 110V/220V for your choice_x000D_ Output frequency: 220V 50Hz, 110V 60Hz._x000D_ Peak power: 4000W_x000D_ Rated power: 300W_x000D_ Output waveform: corrected sine wave_x000D_ Product size: 16.5x10x7.8cm _x000D_ Application:_x000D_ -Applicable load with rated power below 300W: (5W mobile phone, 5W milk pump, 10W digital electronic equipment (Ipad/car navigation/digital camera), 10W game console, 5W-10W electric shaver, 20W-LED lamp, 25W walkie talkie, 50-100W laptop, 60W compact fluorescent lamp, 60W incandescent lamp, 60W mechanical and electrical 9 fan, 60W-150W TV, 80W-VCR, 180W desktop computer) _x000D_ Note:_x000D_ Please ensure that the rated power is higher than the electrical appliance you want to apply.
