USB powered universal charger

First, empty an ordinary universal charger

Option 1:

The circuit board installed in the Samsung mobile phone battery charger has a disadvantage that it is necessary to install a detection contact at the contact point of the universal charger.

Option 2:

Install a 5V mobile power boost board (this is the only board I have) or other boards.

This does not need to detect the contacts, it will automatically jump when fully charged. If you do not remove the battery after it is fully charged, you can also output 5V through the large USB port as a mobile power source (now only using its charging part)
