  Some Frequently Asked Questions about Power Adapters(图1)

  Electronic products occupy a large market in today's society, because every one of us needs it. With electronic products, power adapters are indispensable, but many people do not understand a lot about this kind of problem. Due to the wide range of applications of power adapters, the common problems of power adapters we are talking about today are some of the things we can touch at present, and the most common ones are books. Although such people are not unfamiliar with power adapters. But there are still some doubts about the power adapter.

  The first question to talk about is the problem of voltage and current. Everyone can see the voltage and current values written on the power adapter. In fact, the voltage marked here is a pure voltage value, that is to say, the upper limit of a voltage when there is no current output. The main purpose is to keep the output voltage at a constant value when it is sent to the computer and pass through other devices. In this case, the safety factor is greatly improved, and the life of the machine can be effectively extended. The current mentioned here is the maximum current value that the device can withstand. If it exceeds, it may burn out. The second thing to talk about is the second question, whether the same nominal voltage can be used on the same laptop when the current is different. The answer is no, in fact, it mainly depends on the resistance. It's fine if it's within the adaptable range of the resistance. But once the resistance is exceeded, the problem of burning out the computer will occur. This is just like when we turn on many electrical appliances at the same time, the fuse will burn out. The so-called fuse is also a resistor. When the current is too large, the resistance cannot adapt, and the problem comes out. The third problem is that many people wonder why the machine is the same, and their power supply is always hot, while others' power supply is not, at most, it is warm. In fact, there is no need to worry about this problem at all. The computer may be overheating because you are running too many things, the CPU is running at a high speed, or the USB charger may also increase the load on the computer. It is not surprising that this problem occurs. The last thing to say is why the original power supply is always better than the later re-purchasing. Because the original power adapter is a set, and all the operations of the machine are in the same system, so it has a long life and is more reliable. Although the replacement looks similar on the outside, the internal resistance is more or less different, and the problem of excessive internal resistance often occurs, so of course, the original one is better.

  In fact, whether it is a USB charger, a switching power supply, or a power adapter. This type of product has high quality requirements. Therefore, when selecting machinery and equipment, the quality of such incidental products must be paid attention to, which is directly related to the life of the machine and the overall value. . This kind of problem cannot be ignored, because every one of us will use power switches, and most people choose good things. So trust the public's vision, Shenzhen Senshuqiang Electronics Co., Ltd. is absolutely trustworthy.
