The ChargeCard is as thick as two credit cards and easily fits in any wallet.

ChargeCard wants to prevent future battery disasters by being the portable power connecter that is always by your side — or at least in your pocket.

A year after ChargeCard's Kickstarter success, the portable power connecter is finally making its way into online stores. The $25 device is as thick as two credit cards and comes with either a micro USB port, 30-pin connector for older iPhones or lightning port for the iPhone 5. The ChargeCard plugs into any USB power source, charging your phone without the tangled mess of a USB cord.
