CAUTION:1.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).2.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 500W3.Tighten the Positive (+) and Negative (-) terminals when the car converter is in use.4.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.5.The car converter suitable for DC12V and Car ONLY, not applied for DC 24V and airplane.6.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.7.If you wanna run a inductive load for a long time, it`s suggested to buy a pure sine wave inverter.8.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: 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. If input voltage display is low, customer needs to charge the battery before using it. Cause the battery is out of power, the inverter is in a protected state.This is a power inverter,using STM-chip technology and kinds of intelligent protection,high reliability.Widely used in cars, steamboats, mobile offering post and telecommunications, public security, emergency and other field.Dual LCD digital display enables you to hold the output voltage and battery voltage value at any time.Fault prompt function.In addition to different sound prompts, it can also be displayed more intuitively from the display screen (for example, battery undervoltage, battery overvoltage, overload, high working temperature, output short circuit, etc.).The overload delay closing functionis added in the product to solve the sensitive problem of inverter protection when the soluble electrical appliance is started.The small power non professional user market has increased the positive and negative pole return protection function.Intelligent temperature control oil sealing fan. When the inverter is working, it can work at a certain temperature, which is more energy-saving and quieter.Digital MCU control, output wave type, more accurate frequency, accurate output voltage, fast response of protection circuit.Color:Black / Yellow (Optional)Output waveform:Modified sine waveOContinuous power:500WPeak power: 6000WInput voltage: 12VInput voltage range: 9.5V-15.5VOutput frequency is: 50Hz for 220V model /60Hz for 110V model.Output voltage range: 110V 10% / 220V 10%Frequency: 50Hz / 60HzInverter efficiency: 0.9Circuit topology: push and encourage typeNo load current: 0.7ALow voltage protection: with a minimum protection voltage of 9.5VHigh voltage protection: with a maximum protection voltage of 15.5VOverload protection: YesOutput short circuit protection: YesReverse connection protection of positive and negative poles: YesOutput voltage stabilization: YesProtection buzzer: YesUSB interface: 2.1A x 2Input terminal connection mode: terminalOutput interface: international general socketSize:16.3cm/6.4inch x 10.0cm/3.9inch x 7.7cm/3.0inchPackage Included:1 x Power inverter1 x Alligator clip1 x Cigarette lighter1 x English Manual
