Feature:Brand new and high qualityOne AC Outlets and two usb ports can offer 100% fast charging for Mobiles phones, computers, laptop,breast pump, Nebulizer,Razors,medical rescue device,emergency equipment etc,can be as a Emergency Power SupplyBattery Level Bar for LED Display shows the battery Capacity, which can remind you that when your battery no power. When connect the battery with inverter, this LED Screen work and show the real-time capacity of battery. It have five level (lattice) of the Battery Level Bar, and each lattice represents 20% of the battery power. When your_x005fbattery is no power, the display will flash to remind you that you need to charge your battery.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 and compact, ideal for vacations, camping and work trips. It can be plugged into almost any 12V power output vehicle, providing charging opportunities anywhere.Car power inverter with 2 USB ports and AC outlet. surge power: 4000W/6000W, The power inverter comes with free cigarette lighter and 2pcs battery clips,providing 300Watt/500Watt continuous power, 4000watt/6000watt peaks power (Please make sure that the total rated power of the connected devices is 300W/500W).Available Ranges Of Rated Voltage Of Electrical Appliances : 200~240V, 100~120VSpecification: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 protectionOutput voltage : AC 110V /220V for your choiceOutput frequency is: 50Hz for 220V model /60Hz for 110V model.Peaks Power : 4000W/6000WRated power :300W /500WOutput waveform: Modified sine waves.Size:20.5cm/8.1inch x 11.7cm/4.6inch x 5.8cm/2.3inch.CAUTION:1.This is a modified sine wave inverter,NOT applicable for devices which work by built-in motor, hair dryers,air conditioners, coffee machine,water pump, induction cooker,refrigerators and microwave ovens etc.Make sure that the total rated power of the connected devices is 400W2.Tighten the Positive (+) and Negative (-) terminals when the car converter is in use3.If the converter is directly connected with the cigarette lighter. The highest out put power must be under 150W. If higher than 150W,we strongly recommend you using the Crocodile Clips to a battery ,because car cigarette lighter might not afford power over 150W.4.The car converter suitable for DC12V and Car ONLY, not applied for DC 24V and airplane5.Please do not leave the inverter in the ON position before car start.It's easy to damage the inverter before connected to the battery.The correct operation is connect to the battery first and then turn on the inverter switch6.It's normal for the inverter to become warm while you are using it.In order to get the best using results, please put the inverter on the flat surfaceThe working place should meet the following criteria:Keep dry, should not let the inverter contact the water or other liquids, keep the inverter away from moisture or water.Cool environment, keep the temperature between 0 Celsius degrees and 40 Celsius degrees.Do not put the inverter next to heat vents or other devices.Try to keep the inverter not be shined directly by the sunshine.Package Included:1 x Power Inverter2 x Battery Clip1 x Cigarette Lighter Plug1 x English Manual Produced by yougang
