  Nowadays, with the continuous development of technology, new electronic products are constantly appearing, so many electronic products are indispensable for power adapters, but for many people, there are actually many incorrect operations when they are used. On the one hand, they will be caused by improper operations Issue safety hazards, on the other hand, improper use methods lead to a reduction in the service life of electronic products,

What problems should be paid attention to when using the power adapter?(图1)

  1. Do not use a power adapter with insufficient voltage and current

  This is similar to the first taboo in the use of battery packs, but here is from the perspective of the whole machine. Nowadays, the configuration of notebook computers is getting higher and higher, and the power consumption is also rising, especially the high-frequency P4-M machines are even more power-consuming. Once the voltage and current of the power adapter are insufficient, it is easy to cause the screen to flicker, and the hard disk is bad. Problems such as the battery cannot be fully charged and the machine freezes for no reason.

  Powered by battery, the output of the battery is pure DC, which is very clean. The voltage of the battery is neither possible nor need to be designed to be very high. The chemical characteristics of the lithium battery determine that the output voltage of a cell can only be around, so many batteries They all use a three-stage series connection, which has become a very popular battery voltage. The nominal value of some batteries is slightly larger than an integer multiple, such as or etc., in fact, to protect the battery.

  If you are used to removing the battery and plug it directly into the power source, it is more likely to cause damage (the battery can act as a buffer here). The most terrible thing is that these problems do not appear immediately, but only after a period of time. When the problems occur, they are often helpless. In addition, when the current and voltage of the power adapter are insufficient, the line load may increase, and the machine heats up inversely than usual, which is detrimental to the life of the notebook computer.

  Power supply, the situation is more complicated. First, the added voltage needs to be further stabilized and filtered to ensure stable operation when the power supply performance is not very good. The stabilized voltage is divided into two parts, and the work is supplied all the way. , The other way to charge the battery, the part that supplies power to the notebook is the same as when the battery is powered.

  2. Avoid falling or flooding

  For the sake of portability, the internal structure of the laptop power adapter is very compact. Although it is not as fragile as a battery, it should also be avoided from impact and fall. The author once used a fallen power adapter and caused a trip at home. Later, I found out during inspections. It has been short-circuited internally. As for flooding, because most of the power supplies are on the ground, they are often found after flooding, so you should develop a good usage habit, first connect the listed power terminal and then plug the laptop into the laptop, and try not to put the power directly on the ground , And put it where you can see it.

  The part that charges the battery needs to be added to the cell through the battery's charge control circuit. The control circuit can be very complicated, so the power supply voltage must be greater than the cell voltage to have sufficient capacity to supply each unit of the charge control circuit.

  3. Avoid poor heat dissipation

  Many people attach great importance to the heat dissipation of notebook computers, but few people care about power adapters. In fact, the power adapters of many machines have no less heat than notebooks. Be careful not to cover them with clothes and newspapers, and place them in a well-ventilated place. In this regard, I have personal experience of a notebook I used in the early years, because the power adapter itself is very hot, and it is convenient to use it on the bed. As a result, the surface is partially melted because the heat cannot be discharged.
