Introduction: Rechargeable (homemade) Power Bank (super Easy)
Step 1: Intro
This is my first tutorial so go easy on me xD. Ok I made this charger because tired of being with out music (ipod) on school.because my school does not have power plugs.
Step 2: Partss!
Ok we need: 3x ultrafire 3.7v batteries or 3x 4 volts batteries 1xcar cell phone charger 1x toggle switch Pair of cables 1x rca female plug (you will see its use later) Tools: Hot glue Scissors Black tape Pliers
Step 3: Building This
Now comes the good part.connect the 3 batteries in series if they are 3.7v they shoud give 11.1v out.now take apart the car charger.connect positive cable of batterie to center stem of the toggle switch.then connect the negative cable of the battery to the car charger and the rca female plug.connect the car charger positive cable to the right stem of the toggle switch and the positive cable of the rca female plug to the left stem of the toggle switch.
