The ChargeCard is an ultra-portable USB charging cable in the shape of a business card.\u00a0ChargeCard is just\u00a0three times the thickness of a credit card, and\u00a0it easily\u00a0fits into a wallet, purse or pocket, according to its manufacturer. And there's an iPhone-specific version and a version for smartphones with\u00a0micro USB ports.\n\tThe iPhone ChargeCard.\n\tChargeCard: Simple, Practical Concept\n\tThe ChargeCard is not a\u00a0portable battery, and\u00a0cannot\u00a0power up\u00a0a smartphone on its own. When the gadget is open\u00a0it has a standard USB connector on one end and an iPhone port or micro-USB connector on the other. You simply plug the USB side into a compatible\u00a0port and connect your smartphone, and it begins\u00a0to charge. The ChargeCard works as a data cable too, so you can use it to\u00a0transfer files or sync other data.\n\tThe ChargeCard\u2019s body is made of tough ABS plastic,\u00a0and the foldout USB arm is made of a flexible thermoplastic\u00a0material for durability. The iPhone version's\u00a0connector port\u00a0protrudes far enough out from the unit's body\u00a0to work with bulky cases, such as OtterBox cases.\n\tThe ChargeCard is just 0.1-inch thick and 3.25-inches long, just slightly shorter than an average credit card.\n\tIt's worth noting that some recent rumors suggest Apple will release a new iPhone with a different port connector, so ChargeCard may not be compatible with that new device. But ChargeCard is compatible with in-market iPhones and smartphones with micro USB ports.\n\tThe ChargeCard in action.\n\tChargeCard Availability\n\tThe ChargeCard is a KickStarter project, and it\u00a0has already surpassed its funding\u00a0goal of $50,000 with a month before the funding period closes. The iPhone ChargeCard is expected to ship in September, and the micro USB ChargeCard is expected in November. The project was initially posted on Kickstarter as an iPhone-only charger,\u00a0but the\u00a0creators quickly\u00a0added a micro USB ChargeCard due to popular demand.\n\tA pledge of\u00a0$18 or more will get you a micro USB version, and a pledge of $20 or more buys the iPhone version.\u00a0You can also\u00a0pledge $35 or more to get one of each ChargeCard.
