Step 1: Preparation

Materials:

  • Altoids container or small container
  • cell phone car charger
  • gator clips/cables (2)
  • 9V battery
  • 9V battery snap connector
  • electrical tape

Tools:

  • scissors
  • metal cutters/metal snips

Step 2: Wiring

Take your gator clips and connect one end of the gator clip to the positive wire of the snap connector. Connect the other end of the gator clip to the metal contact on the end of the car charger.

Take one end of the second gator clip and connect it to the negative wire of the snap connector. Connect the other end to one of the metal contacts on the side of the car charger.

Then wrap all the connections in electrical tape so the metal container doesn't interfere with the circuit.

Step 3: Cutting

Connect the 9V battery to the snap connector and put the wiring in the Altoids tin. On the outside of the Altoids tin, mark where the USB plugin is located. Then use metal cutters/metal snips to cut out the section you marked.

Step 4: Finishing the Project

Insert the wiring, 9V battery, and car charger into the Altoids container. To use, insert your phone's USB charger cable into the USB port though the hole in the Altoids container. Then plug it into your phone. Now you have a homemade portable phone charger that you can keep in your pocket or glovebox!
