Great bargain for this handy product.
Don't know if this is local or not but it was part of their "Massive Stock Clearance" at PC World in carlisle (i got the last 2 packs so no more at carlisle).
Introducing our revolutionary new rechargeable battery - the USBCELL.
This NiMH AA cell can be used like a normal battery and can be recharged simply by plugging into a USB port.
With over 15 billion Alkaline batteries made and thrown away each year - wasting resources, C02 and creating toxic Landfill - USBCELL offers a eco-friendly alternative as can be re-used hundreds of times as no charge adaptor or cable is needed, saving you money, hassle and waste.
