ChargeCard for iPhone by Noah Dentzel + Adam Miller β Kickstarter
Nick Sullivan stashed this in technology
It's a clever concept, but I cannot tell how much of a charge it'll offer.
My mophie gives me several hours' worth of extra charge, and I carry it as the case for my iPhone.
If ChargeCard offers under an hour of extra charge, it's probably not worth it.
Adam, it's not a battery. It's a replacement for the USB connector that is always with you.
Thanks Nick, I was confused when they called it CHARGEcard. :)
