At a time when almost everyone has a smart device, there are more and more power adapters in people's homes. Take the notebook computer as an example, sometimes the notebook is damaged or replaced, and the power adapter becomes useless. Some people choose to throw it away, and some people choose to use it for other devices of the same type, but in fact, the same type of power adapter is not necessarily universal. This article will summarize three common reasons why the power adapter of notebook computer is not universal.
Different interfaces:
Most laptop power adapters have different interfaces between brands, which means that other brands of power adapters can't be plugged into your laptop at all. Different interfaces are relatively safe, because at least you won't plug in a power adapter that doesn't match the current or voltage to power the laptop, causing damage to the computer hardware.
Different voltages:
Different brands of notebook computer power adapter voltage is not the same, even if the power adapter interface is the same, can not use different brands of notebook computer power adapter for power supply.
Different currents:
The current of different brands of notebook computer power adapters is also different.
Among them, the interface is the most important. If the excuse is wrong, there will be all kinds of problems. The second is the voltage, as long as the voltage is close to 5%, it should be universal. In addition is the current, the large current can be used in the small current machine, but the time should not be too long. Finally, there is the problem of interface compatibility, and interchange is definitely not possible.
Therefore causes the notebook computer power adapter not to be universal the reason mainly to have the connection, the voltage, the current and so on three reasons. I believe that after reading this article, you will be able to have a better understanding of the problem that the notebook power adapter is not universal.
