Although many devices in life use power adapters, many people still don't understand it. Faced with the various problems of power adapters, we must have a simple understanding of them before purchasing and using them, so as not to be deceived by the merchants! Today, the power adapter manufacturers will summarize and answer everyone’s questions!
1. Is the laptop power adapter a battery or a charger?
The power adapter of the notebook is similar to the power supply components in the desktop computer. It is a matching AC power converter specially designed for the notebook. It can supply power to the notebook and charge the battery at the same time. It is a portable power source.
2.How to test the aging of the power adapter?
Aging test simply means that the power adapter is fully loaded for a certain period of time, to see what problems the power adapter will have. Generally, it is very conventional to age at least several hours. Of course, this time can be considered according to the pursuit of the quality of this power adapter and the cost.
The most important thing is that most of the power adapter products that flow out of the production line already have all their functions and can be used directly. However, if the aging test is not done, then many problems may occur in the early stage of power use. For example, short circuit, no voltage, no current, and even explosion are possible, but these problems can be completely avoided after the aging test. Of course, problems occur after using for one year or more. That is the life of the power supply. There is no way. controlling. Power adapter products that have undergone burn-in testing are safer.
3. What is the difference between a power adapter and a power supply?
Adapter To be precise, what kind of device adapter should be mentioned. For example: the power adapter of the mobile phone, the adapter of the shaver, etc. In short, it is a device. The meaning of the power supply is different, as the name suggests, the power supply is the source of electricity. There are AC power sources, such as our common household power sources, and in general, the power grid, there are DC power sources, such as dry batteries and batteries.
4. Can desktop power adapters be universal?
As long as the voltage sockets and the polarity are the same, they can be used with each other, but the small current cannot carry a large load.
After reading the above introduction, I believe that everyone has an understanding of the above problems of the power adapter, and you can be confident when you buy it. I hope everyone can buy suitable products!
