How to operate the car inverter correctly?
Jul 23, 2022
The on-board inverter output from the cigarette lighter can be 20W, 40W, 80W, 120W to 150W power specifications. By connecting household appliances to the output of the power converter, you can use various appliances in the car as easily as at home.
What is an inverter and how does it work?
Because this article is mainly to explain how to use the car inverter, the main purpose is to help novices solve daily use problems. Therefore, in terms of explaining the principle, we only make a basic introduction, and also invite some technical control to understand. Of course, if you are not interested in this electrical knowledge and are a complete novice, you can also skip to the next summary and go straight to the main topic.
How to choose the right inverter for you
At present, the auto parts city, major e-commerce, and shopping malls are flooded with a large number of various inverter power supplies, which are cheap by tens of yuan, even hundreds of yuan or even thousands of yuan. The maximum power it can carry varies from tens of watts to hundreds of watts. So which inverter should we choose?
First of all, for ordinary home users, it is enough to buy an inverter with a maximum power limit of 300W. Because the fuse current used by the 12V power supply of most household cars is less than or equal to 20A, that is to say, the maximum allowable electrical appliance is about 230W. Some old models even allow the maximum current of insurance to be only 10A, so choosing a car inverter cannot blindly covet high power. At present, most inverters connected to 12V power supply can only be used for electrical appliances below 150W.
For some outdoor workers who need to use high-power appliances, you can buy an inverter directly connected to the battery. This inverter can be used for appliances above 500W, driving small motors and some 1000W photography softboxes at every turn.
As for the grade of the inverter, in addition to our traditional workmanship materials and brands. In terms of performance, they are also very different. At present, inverters that output pure sine waves and quasi-sine waves are mainly sold on the market. Among them, the price of pure sine wave inverter is relatively high, starting from 500 US dollars, and the mid-range product is about 1000 US dollars, but the performance is very stable. The 120V AC output quality of some high-end products is even higher than our daily life. use electricity. Inverters that belong to the square wave category, such as quasi-sine wave or modified sine wave, are stable in most cases, are more cost-effective, and are suitable for the category of inverters for ordinary consumers.
As for how to distinguish the output waveform of the inverter you purchased, this is very simple. The packaging specifications of all inverters will clearly state the continuous output power, output waveform and other data of the inverters sold.
The use and precautions of ordinary inverters
The maximum current that the car 12V power supply insurance can withstand will not be too high. Of course, there is no uniform standard. In most cases, each car manufacturer will design the maximum allowable current to 15A or 20A. There are also a few cars, especially some older cars, that use 10A insurance. Therefore, when we use the inverter used in ordinary cars, we must know how much current is allowed by the insurance corresponding to the 12V on-board power supply of our car. There is no benefit other than the burnout of the insurance inside.
In daily life, most of our digital products such as mobile phones, cameras, computers, tablets, etc. require low-power charging, rarely exceeding 100W, which can be used with confidence, but like some of our own commonly used heating equipment - self-driving tours usually have high power , such as hair dryer, fast heating, electric hot water bottle, etc., easily exceed 1000W, and must not be connected to the inverter in the car.
Use with care, misuse is dangerous
At this time, some friends may be worried. If the inverter current is too high, in addition to burning the fuse of the inverter and the 12V power supply in the car, will it burn other electrical appliances in the car or affect other electrical appliances? Generally speaking, in theory, that is to say, all the electrical appliances in the car were connected in parallel before, so burning the insurance will only affect the use of the 12V power supply, and will not affect other electrical appliances in the car.
