Specifications:Name: Car power inverter.Input voltage: DC 10.5V~15V,(When the battery voltage is lower than 10.5V, the inverter is low voltage protection, when the battery voltage is higher than 15V, the inverter high voltage protection).Output voltage : AC 110V /220V for your choice.Output frequency is: 50Hz for 220V model /60Hz for 110V model.Peaks Power: 600W.Rated power: 300W.Output Waveform: Modified sine wave.Product Size: 16.5x10x7.8cm.Application:-Applicable Loads for Rated Power under 300W:5W-Cell phone.5W-Breast pump.10W-Digital Electronics(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 Electric9 Fan.60W-150W TV .80W-VCR.180W-Desktop Computer.Note:Please Ensure the Rated Power is higher than the electric appliance you wanna apply to. We recommend you buy a larger model than you think you'll need (at least 10% to 20% more than your largest load).And if you wanna run several appliance at the same time, you should refer to the total Watt.If you wanna run a inductive load for a long time, it`s suggested to buy a pure sine wave inverter.Adavantage:[4000W Power inverter] Car power inverter with 2 USB ports and AC outlet. he power inverter comes with free cigarette lighter and 2pcs battery clips, providing 300Watt continuous power, 4000watt peak power (Please make sure that the total rated power of the connected devices is 300W).[LED Green&Red Work Lights] When inverter work normal, the green LED Lights work and tell you it is working well, but when it is on protection status, such as low voltage, high voltage, over temperature, or over load, the Red Led Lights will light up and you need to turn off the inverter, and check which protection function is work, and try to solve it then the inverter can work again.[LED Screen display] LED Display shows the battery Input voltage, output voltage. Cigarette lighter cable can supply power for device easily. If the out put power is higher than 150W, please using the Crocodile Clips to a battery.[Fast Charging Dual USB ports ] One AC Outlets and two usb ports can offer 100% fast charging for Mobile phones, computers, laptop,breast pump, Nebulizer,Razors,medical rescue device,emergency equipment etc,can be as a Emergency Power Supply.[Multi Protection] Built-in fuses, safe charging design and cooling fan prevents the car power converter from over-heat,saving power and energy. over voltage, overload, over-current, short circuiting, under-voltage, overheating, short circuit protection.[Lightweight design &Top Quality] Lightweight and compact, ideal for vacations, camping and work trips. It can be plugged into almost any 12V power output vehicle, providing charging opportunities anywhere.
