Just follow these steps to update the new USB interface
1. Use a screwdriver and blade to disassemble the charging bank and take out the mainboard.
2. Prepare a heat gun and tweezers, and blow the USB interface on the motherboard with a heat gun at 250 degrees until the interface can be removed with tweezers.
3. Apply tin paste to the USB interface of the motherboard, place the new USB interface on the motherboard to apply tin paste, and blow the tin paste with the 250 degree hot air gun until it melts.
In the absence of a heat gun, you can also use a soldering iron to replace, but pay attention to control the time and temperature.
Hard to change
It's hard to change but you can charge it by buying a double-header link.
Disassemble the shell to see the chip scheme used. Then according to the chip data, find the corresponding control pin, and then skip some functions can be used as an ordinary charging bank.
That is to modify the charging port of the charging bank. Now the mobile phone bought is basically type-c interface, Apple users please ignore, but since you can change.
Can be changed, as follows:
1. There are usually only two interfaces on the power supply group, one is the standard USB interface (discharge port), and the other is the micro USB interface (charging port).
2. Replace the damaged interface. Pry open the casing and remove the circuit board.
USB Type A is generally used in personal computers and is the most widely used interface standard.
USB Type B is generally used for 3.5-inch mobile hard drives, printers, and displays.
Charging treasure is not allowed to change the interface.
