Another one of my charger creations but doesn't seem to work for iPhones though, just give me tips on the comments aside! It's gives off 6vs and is very simple
Step 1: First Your Tools
Wire stripper, cutter, battery pack of four, a female USB port as well.
Step 2: Prepare Wires
The diagram shows the USB ports wires and is just easy to define and separate the data wires from it. And connect it to the positive and negative on the battery pack
Step 3: Connect and Try It Out
Uif it didn't work for your phone, sorry I'm new at this and tried it off a lot of other ideas of a portable charger. Give comments on what I can change and follow on instructables!
