What Is The Power Adapter? Can It Be Generic?

What is the power adapter? Can it be generic?

Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, power transformers and rectifier circuit, according to its output type can be divided into AC output and DC output type; according to the connection can be divided into wall Type and desktop. Widely supporting the phone son machine, game consoles, language repeaters, Walkman, notebook computers, cellular phones and other equipment.

In some cases suddenly laptop battery power shortage, and no power adapter, this situation is very anxious and embarrassing. Some friends may try to borrow other people's laptop power adapter, but we should pay attention to the different brands of notebook computer power adapter is not universal.

There are three main reasons:

First, the interface is different Most of the laptop power adapter brand interface between the different interface is relatively safe, because at least you will not insert the current or voltage does not meet the power adapter to the laptop power supply, which led to computer hardware damage.

Second, the voltage is different from different brands of laptop power adapter voltage is not the same, even if the power adapter interface is the same, can not use different brands of laptop power adapter for power supply.

Third, the current is different from different brands of laptop power adapter current is not the same, even the same brand of notebook computers between the use of power adapter to confirm the voltage and current specifications.

As for the laptop power adapter heat problem, regardless of any power supply has a certain internal resistance, so when the power output current, will produce a pressure drop inside, resulting in two things, one is to generate heat, so the power will be hot, the other Is the result of the output voltage is reduced, the equivalent of internal consumption. But the longer you work, the greater the amount of heat will be greater.
