1Car power inverter with 2 USB ports and AC outlet. surge power is up to 6000W. The power inverter comes with free cigarette lighter and 2pcs battery clips,providing 500Watt continuous power, 6000watt peak power (Please make sure that the total rated power of the connected devices is 500W). 2Battery 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 realtime capacity of battery. It have five level (lattice) of the Battery Level Bar, and each lattice represents 20% of the battery power. When your battery is no power, the display will to remind you that you need to charge your battery. 3One AC Outlets and two USB ports can 100% fast charging for mobile phones, computers, laptop, breast pump, Nebulizer, Razors, emergency equipment etc,can be as a emergency power supply. 4Builtin fuses, safe charging design and cooling fan preventing the car power converter from overheat, saving power and energy. Alos provides over voltage, overload, overcurrent, short circuiting, undervoltage, overheating, short circuit protection. 5Lightweight and compact, ideal for vacations, camping and work trips. It can be plugged into almost any 12V power output vehicle, providing charging opportunities anywhere. Condition: 100% Item Type:Car Inverter Material: ABS Color: As the Picture Shown 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 Frequency: 50Hz for 220V model / 60Hz for 110V model. Peaks Power : 6000W Rated power: 500W Output Waveform: Modified Sine Wave. Safety Protection Function: Reverse Polarity Protection, Low Input Voltage Protection, High Input Voltage Protection, Over-Current Protection, Short Circuit Protection, Over Temperature Protection, Overload Protection, Internal Fuses. 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 400W 2.Tighten the Positive (+) and Negative (-) terminals when the car converter is in use 3.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 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 airplane 5.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 switch 6. 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 surface The working place should meet the following criteria: (1) Keep dry, should not let the inverter contact the water or other liquids, keep the inverter away from moisture or water. (2) Cool environment, keep the temperature between 0 Celsius degrees and 40 Celsius degrees.
