How to choose a DC power supply when repairing a mobile phone
As we all know, computer maintenance and mobile phone maintenance are inseparable from DC power supply. It can be used to test the voltage and current, charge the battery, and judge the short-circuit fault point. But how to choose the right DC power supply? Today, we at Phonefix will share with you the selection guide for DC power supplies.
In terms of form, DC power supply can be divided into two types: pointer type and digital display type. The previous mobile phone repair masters preferred the pointer power supply. They think it is very intuitive that the pointer shows the current change.
It is the same reason that some masters like to use pointer multimeters, but with the development of maintenance technology, it is an unstoppable trend for digital display power to replace pointer power. The result is more accurate.
Choose a suitable DC power supply, we can also directly connect the iPhone battery, and insert the data cable into the blue USB port for testing.

The parameters of the power supply are also various, how to choose?
In fact, the most important thing is the choice of voltage and current. Common voltage parameters on the market are 0–15V and 0–30V. This parameter refers to the maximum output voltage. Because repairing a phone only uses 5V at most, these two should be enough.
The choice of current is more important. Within the acceptable price range, the higher the current, the better, because the performance of smart large-screen computers is getting stronger and stronger, and the power consumption is also increasing. The CPU performance of some machines even exceeds the performance of computer CPUs a few years ago.
