How to choose a car inverter?

The car inverter is a power product that works in a high-current, high-frequency environment, and its potential failure rate is quite high. Therefore, consumers must be cautious when buying:
First of all, choose from the inverter output waveform, it is best not to be lower than the quasi-sine wave;
Secondly, the inverter must have a complete circuit protection function;
Third, the manufacturer must have a good after-sales service commitment;
Fourth, circuits and products have been tested for a period of time.
1. In addition to the price factor when choosing a car power supply, the main considerations are the input voltage requirements and output power of the car power supply. In addition, since the power of various electrical appliances varies greatly, the car power supply should be selected according to the use requirements. It is sufficient for the main use.
2. According to the types of electrical appliances used, you need to choose a suitable vehicle power supply. For daily resistive electrical appliances, you can choose square wave, modified wave, and sine wave. You must choose sine wave inverter for inductive electrical appliances. Device.
3. The square wave/modified wave inverter power supply cannot carry inductive loads and capacitive loads, cannot drive air conditioners, refrigerators, and cannot provide power for high-quality audio televisions. Strictly speaking, the square wave/modified wave inverter power supply will affect the service life of electrical appliances, and these problems will not occur when using a sine wave inverter.
