This conveniently-sized 30-pin to USB connector is no thicker than a credit card but will allow you to hook your precious iPhone up to any computer for a quick juice up. I’d like it even more if it had a built in battery though.
The ChargeCard is a “charging cable” that takes up no space at all. You can put it in your wallet and take it out for emergencies. We’ve all been in situations where we could have used something like this. When it’s not in use, it’s as slim as a credit card. While it’s pretty smart, you won’t be able to use your iPhone while it juices up, so that could be a problem, and it really isn’t practical for use with a traditional wall charger since the flexible USB cable is very short.
ChargeCard was launched as a Kickstarter project, and you can get in on the action for $18(USD).
