Specification: Item Type: Car Power Converter Material: Aluminum Alloy +ABS+ Rubber Continuous Power: 2000W Peak Power: 4000W Input Voltage: DC 12V Output Waveform: Modified sine wave inverter How to use: 1. The DC and the voltage must be in consistent. Each inverter has a fixed value of DC and voltage , such as 12V, and the battery voltage must be selected to be consistent with the inverter's DC input voltage. 2. The output power of the inverter must be greater than the power used by the electrical appliances, especially for electrical appliances with high power when powered on, such as refrigerators and air conditioners. a larger output power should be needed. 3. The positive and negative poles must be connected correctly. The DC voltage connected to the inverter is marked with positive and negative poles. Red is positive (+), black is negative (-), the battery is also marked with positive and negative, red is positive (+), black is negative (-). It must be connected at this way: positive (red to red), negative to negative (black to black). The diameter of the connecting wire must be thick enough, and the length of the connecting wire must be reduced as much as possible. 4. It should be placed in a ventilated and dry place, beware of rain, and have a distance of more than 20cm from surrounding objects, and away from flammable and explosive products. Do not place or cover other objects on the machine. The use environment temperature is not more than 40℃. 5. Charging and inverter cannot be carried out at the same time. That is, do not insert the charging plug into the electrical circuit of the inverter output during the inverting process. 6. The interval between two starting-ups is not less than 5 seconds (You should cut off the input power). 7. Please wipe with a dry cloth or anti-static cloth to keep the machine tidy. 8. Before connecting the input and output of the machine, please place the shell of the machine correctly. 9. To avoid accidents, it is strictly forbidden to open the outer shell for operation and use. 10. When you suspect that the machine is malfunctioning, please do not continue to operate and use it. 11. When connecting the battery, make sure that there are no other metal objects on your hands to avoid short circuit of the battery burning the human body. 12. The use environment should be based on safety and performance, and the installation environment should have the following conditions: 1) Dry: Do not soak in water or rain; 2) Shady and cool: the temperature is between 0℃ and 40℃; 3) Ventilation: Keep no foreign matter within 5cm on the outer shell, and the other ends are well ventilated. 13. How to Install and Use 1) Put the inverter switch in the OFF position, and then insert the cigar head into the cigarette lighter socket in the car to ensure that it is inserted in place and has good contact; 2) Make sure that the power of all electrical appliances is below the nominal power of the inverter. Insert the 110V/220V plug of the electrical appliance directly into the 110V/220V socket at one end of the inverter, and make sure that the power of the electrical appliances connected to the two sockets is equal, and within the nominal power of the inverter; 3) Turn on the inverter switch, the green indicator light is on, indicating that it is working normally. 4) The red indicator light is on, indicating that the inverter shuts down due to over voltage/under voltage/overload/over temperature. 5) In many cases, due to the limited output power of the car cigarette lighter socket, the converter will alarm or shut down during normal use. At this time, just start the car engine or reduce the electric power to return to normal. 14. Notes: 1) TVs, monitors, motors, etc. will reach the peak power when it is turned on. Although the inverter can withstand the peak power twice than the nominal, the peak power of some electrical appliances that meet
