How to choose a car inverter?

1. The output power of the vehicle inverter must be greater than the power used by the electrical appliances, and there must be enough margin for some electrical appliances with large starting power, otherwise it may not be able to start.

2. At present, many electrical appliances use three-pin plugs, which requires a three-hole interface on the inverter. In addition, the USB interface is also useful, so it is best to choose a car inverter with three interfaces.

3. According to the difference of the output current waveform, the vehicle-mounted inverter is divided into a pure sine wave inverter and a modified sine wave inverter. Among them, the pure sine wave inverter has a stable power supply and can basically drive common electrical appliances well. The modified sine wave is actually closer to a square wave, and the quality of the output current is poor, which will cause certain damage to some electrical equipment. Although the price difference between the two inverters is large, it is recommended to buy a pure sine wave inverter if it is used for a long time.

4. When purchasing a vehicle-mounted inverter, be sure to confirm whether it has functions such as overvoltage protection, undervoltage protection, overtemperature protection, overcurrent protection, and short circuit protection. These functions can not only provide protection for the inverter itself More importantly, it can avoid damage to electrical equipment.

5. Choose an on-board inverter with a metal shell. The on-board inverter is relatively prone to heat due to its high power. If the internal heat cannot be dissipated in time, it will affect the life of the components at least, and cause a fire if it is serious. On the one hand, the metal casing has good heat dissipation characteristics, and on the other hand, it also avoids the danger of fire.
