1, my charger, is the original charger in the original box when I bought millet mobile phone.
2, put on protective gloves, pick up the utility knife, along the plug border gap of the charging head, row back and forth, row on all four sides, moderate strength, row five or six on each side. (Mainly to remove the glue around.)
3, after passing, put the end of the plug on the outlet of the hair dryer, and blow the hot air at close distance with a high-power hair dryer; Blow for three minutes Roll over and blow for another three minutes. (I was lazy enough to put them on the table and blow them at close range.)
4, then pick up the charger, clamp the plug piece with a vise, shake (pull) back and forth, moderate strength, must be moderate strength, open it.
5, look at the way I open it, is not perfect! No damage at all!!
considerations
Pay attention to the temperature, be sure to preheat the temperature, to a little hot hand as well.
When pulling, be sure to pay attention to the strength, do not rush.
Open the housing from the charger pin side, the housing is ultrasonic welded, and the inside of the pin is wrapped with horse tape for insulation.

Take out the internal circuit board, and use copper sheets on the front of the circuit board for heat dissipation.

The back of the circuit board is also covered with large copper heat sinks.

Remove the cooling copper sheet on the front, fill the silicone between the components, and play the role of fixing the components and conducting heat.
