Emerging as a prototype on community funding website KickStarter, the Cord-On-Board case solves your charging problems by incorporating an iPhone USB cord within its case. The case is light and is slim enough to slip in your pocket, ensuring that you can slip it in and out of your pocket to charge it using one of the hundreds of USB ports you encounter each and every day.

I funded this for $25 today, so I can get the first run in March.
