This project details a small & simple, but very powerful USB charger for your mp3 player, camera, cell phone, and just about any other gadget you can plug into a USB port to charge! (See below for compatibility tests)

The charger circuitry and 2 AA batteries fit into an Altoids gum tin, and will run your iPod for hours! 2.5x more than you'd get from a 9V USB charger! (SeeProcess for math/calculations) You can use rechargable batteries too.

Specifications:

Some numbers...

  • iPhone (all types): 3/4 full recharge
  • iPod video (tested, using alkaline batteries): 3hrs more video (1 full recharge)
  • iPod mini (tested w/rechargables): 26 hours more (1.5 full recharges)
  • iPod nano: 4 full recharges!
  • iPod shuffle : 60 hours more , 5 full recharges!

This project is suitable for beginners, some soldering tools are necessary but even if you've never soldered before it should be pretty easy. You can etch a circuitboard and/or breadboard this up, or simply buy a kit from the webshop.

I've also documented the process of designing this kit, in case other people interested in designing and making kits are interested in learning how to start selling their own kits!
