How to perfectly choose the right power adapter, charger

2022-09-08 Views：32

For many people, the concept of power adapter only stays at the stage of charger, but in fact, power adapter is a kind of transformer that is used in a large number of chargers. People who are unfamiliar with power adapters often need to face, which power adapter to use for charging.

Power adapters have a variety of parameters, so it is not arbitrary to use the adapter for charging. Before choosing a power adapter, the first thing to determine the three adaptation conditions.

First, the adapter's interface matches the device.

Second, the output voltage must be the same as the rated input voltage of the load (mobile device), or in the range of voltage that the load (mobile device) can withstand; otherwise, it may burn the load (mobile device).

Third, the output current of the power adapter should be equal to, and greater than, the current of the load (mobile device) to provide sufficient power.

The following is an analysis of the above three adaptation conditions.

First, mismatched interfaces should never be plugged in without expertise, otherwise danger will occur.

Second, for why the voltage needs to be consistent, in principle it is like this - insufficient voltage to drive the load, the battery can not be charged properly, to put it in layman's terms is that the supply does not meet the demand.

Third, for why the need for such a current configuration, which involves the principle of the circuit, we all know that the power supply is an internal resistance, the greater the internal resistance of the greater the loss. So manufacturers in the production of this adapter will be based on the size of the internal resistance, to determine the no-load output voltage in a certain range, and the voltage threshold value corresponds to the current threshold value that we see the nominal value of the current, the greater the nominal value of the current means that the adapter is better with the load capacity. So choosing an adapter with a slightly higher current will not only not hurt the battery, but will make charging faster.

Today, BON has broadly introduced how to choose a power adapter according to their needs, and gives three easier to understand the selection conditions, and then the three conditions are explained separately, I hope you can gain after reading this article, BON will also bring you more basic knowledge about.
