Wow – check this out. Drop your phone into an Everpurse, and it starts charging automatically. Put the Everpurse into your larger bag, or carry it on its own. At the end of the day, place the Everpurse on a wireless charging mat, and you’re ready to go for the next day.
You can order one through their Kickstarter campaign. Expected ship date: March 2013. A bit late for Christmas, but just in time for my birthday in April. Wishlisted!
