DIY Electronics: My DIY Tic Tac Mint Box Universal Cell Phone Battery Charger Built With TP4056 Lithium Charging Circuit

Totally eschewing the Altoids-Schmaltoids route.

I can now charge any cell phone battery without requiring its phone or its charger. I have used alligator clips to connect to the battery. The charger circuit board has a mini USB port but I decided to connect it to a female DC jack to make the gadget more durable. There are two LEDs on the TP4056 charging circuit board – “charging” and “full charge” which can be seen through the mint box.
