ChargeCard

There are a surprising number of awesome credit card-shaped iPhone accessories. One of my longtime favorites has been the GoGoStand, but the ChargeCard looks to be another top contender. As you can see in the image above, it has a Lightning connector on one side and a rubberized USB connector that can be folded out from the middle section. I don't know that I'd use it as my main charger cable, but since I tend to misplace those sorts of things, always having the ChargeCard available in my wallet would give me some peace of mind.

The iPhone 5 model seen above is available for pre-order and should ship in mid-May. If you're looking for an iPhone 4 (30-pin) model, those are available to ship right now.
