If forgetting your iPhone charger when you travel is a constant problem, then look towards this fantastic new invention. This is the JuiceTank, it is an iPhone case with a built in wall plug. So all you have to do is plug it into the wall and walk away. The great polycarbonate case is sturdy for when you drop it, but also has two built in prongs to be able to plug it in.
Here is the official release from their Kickstarter project:
"The JuiceTank is the first iPhone case to feature an integrated wall charger that folds flat to provide maximum portability. The automated plug deploys easily and allows you to plug your phone directly into any outlet. No cords required. No clumsy cords. Nothing extra to carry. Just the protection you need with the flexibility to charge whenever and wherever you want. Poor battery life is one of the biggest complaints about the iPhone. Help us get this product to market and together we will solve this problem once and for all. We are using the funds we raise on Kickstarter for tooling and to begin production. Kickstarter projects that do not reach their goal do not receive any of the funds, so help us get there with time to spare. With your help, we can begin shipping the JuiceTank as soon as Summer 2012."
