‘Continuance’ is a concept idea developed by a group of Chinese designers that features AA batteries with embedded USB ports.
The batteries are supposedly rechargeable and they are able to recharge USB-powered devices such as mobile phones, hand-held gaming devices and cameras by connecting a USB cable from the batteries to the devices.
Though it is only a concept design, it sure seems like a handy and practical concept that most tech-savvy people would appreciate.
