This NiMH AA cell can be used in normal battery applications and can be recharged simply by plugging into a USB port with the built in USB interface. With over 15 billion batteries needlessly thrown away each year, and with the increasing demand for portable power by modern electronic devices - the battery has simply not caught up with the needs of modern life. Traditional rechargeable batteries have never been truly portable as they are dependent on chargers or adpators, and so most consumers prefer single use alkaline cells. With USBCELL we aim to change this balance by enabling consumers to Recharge Anywhere, without needing or carrying an external charger. With over 2 billion USB ports on modern computers and devices USBCELL can be charged easily at work,On the Go, or at home.
