The car inverter is a power product that works in high current and high frequency environments, and its potential failure rate is quite high. Therefore, consumers must be cautious when purchasing. First, select from the output waveform of the inverter, preferably not lower than the quasi-sine wave; secondly, the inverter must have complete circuit protection function; third, the manufacturer must have a good after-sales service commitment; fourth, the circuit and The product has been tested for a while.
1. In addition to the price factor, the main requirement for the vehicle power supply is the input voltage requirement and the output power of the vehicle power supply. In addition, since the power of various electrical appliances varies greatly, it is necessary to select the vehicle power supply according to the use requirements. It is enough to use.
2. According to the type of electrical appliance used, it is necessary to select a suitable vehicle power supply. For daily resistive electrical appliances, square wave, correction wave and sine wave can be used together. For inductive electrical appliances, sine wave inverter must be selected. The device is gone.
3, square wave / modified wave inverter power supply can not carry inductive load and capacitive load, can not drive air conditioning, refrigerator, it is difficult to provide power for high-quality audio TV. Strictly speaking, the square wave/corrected wave inverter power supply will affect the service life of the appliance. These problems do not occur when using a sine wave inverter.
4, the cigarette lighter insurance in the general car is 10A or 15A (10A insurance is mostly old models or imported models), which means that the car inverter power supply that can be used in a general car is 120W or 180W. . If you need a high-power inverter (more than 180W or 200W), you must look at whether there is a battery clamp in the package. There is a limit to the use of a high-power inverter without a battery clamp in a car.
5, the general car power supply will have insurance at the cigarette lighter end, the car supplies Qiqi network reminds you must open the purchase when you check this insurance and the car cigarette lighter insurance does not match (theoretically less than or equal to the cigarette The insurance of the device, so that the cigarette lighter's insurance can play a role, and vice versa, the car cigarette lighter's insurance will burn out, which will cause unnecessary trouble.
