USBCELL released revolutionary rechargeable batteries that can charge from any USB port without the need for any recharging devices, cradles or cables. Simply pop the lid to reveal a built in connector and charger, plug into any powered USB port on your desktop, laptop, keyboard or games console, to charge the battery.
USBCELL can be used exactly like a normal battery meaning there is now no need to purchase huge packs of alkaline batteries, or invest in or carry a clunky charger. Billions of USB ports are readily available in homes and workplaces around the world meaning you never need to run out of power and making the USBCELL extremely cost-effective and convenient for all battery-powered devices.
The batteries can be bought here. Currently they are only available in the UK, the price is £12.99 for a 2 cell pack.
