Application:

Widely used in home theaters, electric grinding wheels, electric tools, sewing machines, DVDs, for VCDs, computers, TVs, washing machines, range hoods, video recorders, massagers, fans, lighting, etc. and other household appliances. Various electrical appliances can be used in the car by connecting household appliances to the output end of the power converter. The electrical appliances that can be used are: mobile phones, laptops, digital cameras, cameras, lights, electric shavers, CD players, game consoles, handheld computers, power tools, car refrigerators, and various travel, camping, and medical emergency appliances and so on.

How to Use:
1. The DC voltage must be consistent. Each inverter has a DC voltage value, such as 12V. 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 appliance, especially for appliances with high power at startup
3. It should be placed in a ventilated and dry place, beware of rain, and be more than 20cm away from surrounding objects, away from flammable and explosive materials, and do not place or cover other objects on the machine. The use environment temperature is not more than 40℃. .
4. 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 inverter.
5. The interval between two startups is not less than 5 seconds (cut off the input power).
6. Please wipe with a dry cloth or anti-static cloth to keep the machine tidy.
7. Before connecting the input and output of the machine, please ground the casing of the machine correctly.
8. To avoid accidents, it is strictly forbidden for users to open the case for operation and use.
9. When you suspect that the machine is malfunctioning, please do not continue to operate and use it.

10. 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.

11. 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 other end surfaces are well ventilated.

12. Installation Method:
1) Insert the cigarette lighter 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 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 to normal.

13. Matters needing attention:
1) TVs, monitors, motors, etc. reach the peak power when starting. Although the inverter can withstand the peak power twice the nominal power, the peak power of some electrical appliances that meet the requirements may exceed the peak output power of the converter. Thereby triggering overload protection, the current is shut off. This situation may occur when multiple electrical appliances are driven at the same time. At this time, turn off the electrical switch, turn on the inverter switch, and then turn on the electrical switches one by one, and turn on the electrical appliance with the highest peak value first.
2) During use, the battery voltage begins to drop. When the voltage at the DC input of the inverter drops to 10.4-11V, the alarm buzzes. At this time, the computer or other sensitive electrical appliances should be turned off in time. If the alarm sound is ignored, The inverter will automatically shut off when the voltage reaches 9.7-10.3V, which can prevent the battery from being over-discharged. After the power supply protection is turned off, the red indicator light will light up;
3) The vehicle should be started in time and the battery should be charged to prevent power failure, which affects the start of the car and the battery life;
4) Although the converter has an overvoltage protection function, if the input voltage exceeds 16V, the converter may still be damaged;
5) After continuous use, the surface temperature of the shell will rise to 60℃. Pay attention to the unobstructed air flow and keep away objects that are easily affected by high temperature.

Precautions:
First of all, use the inverter in strict accordance with the provisions of the user manual;
Secondly, the output voltage of the inverter is 110V or 220V alternating current, and this 110V or 220V power is in a small space and in a movable state, so be extra careful. It should be placed in a safer place to prevent electric shock. When not in use, it is best to cut off its input power;
Third, do not place the inverter in direct sunlight or near the outlet of the heater. The working environment temperature of the inverter should not exceed 40℃;
Fourth, the inverter generates heat when it is working, so do not place objects near or on it.
Fifth, the inverter is afraid of water, so do not expose it to rain or sprinkle with water.

When buying an inverter, you must first understand the voltage and frequency used in your country/region. Purchasing an inverter according to the frequency of your country/region will greatly improve the conversion efficiency of the inverter.
