Specification: Item Type: Power Inverter Material: Aluminum Alloy+ABS+RubberApplication: Suitable for 12V DC vehicles, suitable for cars, motorcycles, ships, emergency work, outdoor work, family emergency and so on.Continuous Power: 1000W Peak Power: 2000W Iutput Voltage: DC 12V Output Waveform: WLD‑T wave inverter How to Use: 1. The DC voltage must be consistent Each inverter has a DC voltage value, 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 at startup, such as refrigerators and air conditioners, a larger margin should be left. 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 (-), must be connected to positive (red to red), negative Connect negative (black connect 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, away from flammable and explosive products, and 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 simultaneously. That is, do not insert the charging plug into the electrical circuit of the inverter output during inverter. 6. The interval between two startups is not less than 5 seconds (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 ground the shell of the machine correctly. 9. In order to avoid accidents, it is strictly forbidden for users to open the case 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 and burn the human body. 12. The Use Environment, Based On Safety And Performance Considerations, 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 shell, and the other end faces 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 plug of the electrical appliance directly into the socket at one end of the inverter, and make sure that the sum of the power of all connected appliances in the two sockets is in the inverter standard. Within said power; 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 overvoltage/undervoltage/overload/overtemperature. 5) In many cases, due to the limited output of the car cigarette lighter socket, the converter will alarm or shut down during normal use. At this time, just start the car or reduce the electric power to return
