Charge Cell Phones Using Li-Ion Batteries - Safe Charging

Make a portable charger for your cell phone using Li-Ion batteries. Yes, safely use rechargeable Li-Ion batteries for cell phone power when and where you need it. You can even use the very popular 18650 cells (I get them for free from salvaged laptop batteries - see video link below).

Previous project videos using similar parts and builds (good for extra reference & how to):

Key parts mentioned in the video include:
- Step up power module to change the battery output into the 5v needed to charge a phone. I got the one used in the video on Amazon (DROK Ultra Small Mini DC Power Module; part #090399).
- TP4056 Charging Module. I purchased on Amazon from MakerFocus (5v micro 1A battery charging board with protection charger module; ASIN B071RG4YMW)
- Project box from Amazon - "VNDEFUL 5pcs black waterproof plastic electric project case" (3.94X2.36X0.98)

WARNING: working with electronics, rechargeable batteries and electric DIY comes with risks. Only proceed if you are confident in your skills and safety techniques. You are fully responsible for any and all outcomes from trying to duplicate any of the actions demonstrated in this or any other DID video. Products used in this video worked for my needs but may not suit all needs so please do the necessary research to know what will work for you.
