What should I pay attention to when using the power adapter?

Nowadays, with the continuous development of science and technology, new electronic products emerge in endlessly, and many electronic products are inseparable from power adapters. However, for many people, there are many incorrect operations. On the one hand, there will be potential safety hazards due to improper operation. On the other hand, improper use methods will shorten the service life of electronic products. Today, the manufacturer of xinjukang power adapter will explain the precautions for the safe use of the adapter.

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

This is similar to the first taboo of battery pack use, but here is from the perspective of the whole machine. Now the configuration of notebook computers is higher and higher, and the power consumption is also higher and higher. Especially the P4-M machine with high dominant frequency consumes amazing power. Once the voltage and current of the power adapter are insufficient, it is easy to cause problems such as screen flickering, hard disk damage, inability to fill the battery and unexplained crash.

Battery power. The output of the battery is pure DC, which is very clean. It is neither possible nor necessary to design the battery voltage very high. The chemical characteristics of lithium batteries determine that the output voltage of a battery can only be about. Therefore, many batteries use three-stage series connection, which has become a very popular battery voltage. For example, in order to protect the battery, the nominal value of some batteries is slightly greater than an integral multiple of, and so on.


Charger manufacturer

If you are used to removing the battery and inserting it directly into the power supply, it is more likely to cause damage (the battery acts as a buffer here). Most importantly, these problems will not appear immediately, but after a period of time. When problems arise, there is usually no way to return to the soul. In addition, when the current and voltage of the power adapter are insufficient, the line load may increase, and the heating capacity of the machine will be greater than usual, which is not conducive to the service life of the notebook computer.

The power supply situation is more complex. First, when the power performance is not very good, it is necessary to further stabilize and filter the additional voltage to ensure stable operation. The stable voltage is divided into two parts, one is to supply power to the book, and the other is to charge the battery. The part that powers the book is the same as the part of the battery.

2. Never fall into the water

For portability, the internal structure of the laptop power adapter is very compact. Although it is not as fragile as a battery, it should also avoid collision and falling. The author once used the power adapter, which led to tripping at home. Later, during the maintenance process, it was found that the internal circuit was short circuited. As for the flood, because most of the power supply is placed on the ground, it is often found after the flood, so we should develop good use habits. First, connect the power terminal in the market, and then plug in the laptop. Try not to put the power supply directly on the ground, but where we can see it.

Components that charge the battery need to be added to the battery through the battery charging control circuit. The control circuit may be very complex, so the power supply voltage must be greater than the battery voltage in order to have sufficient capacity to supply power to each unit of the charging 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, many machine power adapters have no less heating capacity than laptops. Be careful not to cover it with clothes and newspapers and put it in a well ventilated place. In this regard, Xiaobian has his own experience. This is the notebook he used in his early years. Due to the high heat of the power adapter itself, it is easy to put it on the bed. Because the heat cannot be discharged, the surface melts locally.
