Travel or daily life, there are too many digital products may need instant charging. In this case, the vehicle inverter is very important. Of course, in some high-configuration models will be equipped with a 220V AC power interface, but if the car does not have the configuration, you need to use the on-board inverter. So many on-board inverters on the market, how to choose? Xiaobian today to give you the popularization of vehicle inverter purchase knowledge.

What is a vehicle inverter?

The on-board inverter converts the 12V (24V for diesel vehicles) direct current on the car into 220V AC for household use in the car. The vehicle inverter is mainly divided into two kinds, one is connected to the cigarette lighter, and the other needs to install the line by itself. It is recommended to choose a cigarette lighter type vehicle inverter, so there is no need to change the original car line, simple and convenient.

Under normal circumstances, the maximum current that the car 12V power supply insurance can withstand is not very high. In most cases, the maximum allowable current is designed to be 15A or 20A. Therefore, when using the inverter, we must be clear about how much current is allowed by the insurance corresponding to the car's on-board power supply. We think that we can not blindly crave high power, in addition to burning the insurance in the car, there are no other benefits.
Most digital products in daily life require very low power to charge, rarely more than 150W, you can use the inverter to charge, but these heating devices such as hair dryers, heat fast, electric hot water bags, etc., usually have very high power

How to choose their own inverter?

1. Power selection
For ordinary family cars, buying an inverter with a maximum power limit below 150W is fully sufficient. The vast majority of the family car 12V power supply used by the insurance is less than or equal to 20A, the maximum is allowed to 230W or so electrical appliances, some older models, the maximum current allowed by the insurance is only 10A, so the purchase of vehicle inverters can not only covet high power, choose the best suitable power.
For some outdoor workers, people who need to use high-power electrical appliances can buy inverters that are directly connected to batteries. This inverter can be used for 500W or even higher electrical appliances, and can drive small motors and some photography soft boxes at 1000W.

2. Output interface
After the power is selected, it is necessary to see the output interface of the inverter itself. At present, many appliances use a three-pin plug, which requires a three-hole interface on the inverter, in addition, the use of the USB interface is also a lot, so it is best to choose three kinds of interfaces have the inverter.

3. Output waveform
According to the different output current waveform, the vehicle inverter is divided into pure sine wave inverter and modified sine wave inverter. Among them, the pure sine wave inverter power supply is stable, and the common electrical appliances can be driven very well, but the price is higher, and the quality of 220V AC output by some high-end inverters is even higher than that of daily electricity. The modified sine wave is actually closer to the square wave, the output current quality is poor, but in most cases the stability can be guaranteed, suitable for ordinary consumers to buy.

4. Protection function
It is recommended that when purchasing a vehicle inverter, it is necessary to confirm whether it has functions such as over-voltage turn-off, under-voltage turn-off, over-temperature protection, over-current protection and short circuit protection. These functions can not only provide protection for the inverter itself, but more importantly, avoid damage to electrical equipment.
What should I pay attention to when using the inverter?
Vehicle inverter is a kind of power supply product that works in high current and high frequency environment, and its potential failure rate is quite high. Therefore, consumers must be careful when buying. When the owner chooses a vehicle inverter, Xiaobian reminds him to pay attention to the following points:
Look at the output waveform of the vehicle inverter, preferably not lower than the quasi-sine wave; Vehicle inverter should have complete circuit protection function; Manufacturers should have a good after-sales service commitment; Circuits and products have been tested over time; The power of vehicle inverter should not be too large, it is recommended to choose products within 150W;
After the vehicle is turned off, Xiaobian reminds to remember to power off the inverter, the inverter itself as an electrical appliance that will consume electric energy, if the power is constantly powered after the car is turned off, the electricity in the battery will be consumed for a long time.
