Charges 8 AA/AAA at once - plus USB devices.
Uniross Pom 8x AA/AAA battery charger + USB Device charger. Price is obtained by using "LAST20" code at checkout. Seems quite a useful charger for the price (and if you look around Google some other sellers have it at eye watering prices!)

Some blurb :-
The Uniross Pom is a unique and stylish new battery charger that looks more like a desktop sculpture than a battery charging station! With its flawless white shell and sleek curves the Uniross Pom is an exciting eco-friendly energy centre that can recharge up to 8 batteries at the same time. It comes with four AA rechargable batteries to start you off. It is perfect for devices that use both AA and AAA batteries. Place this product proudly on your desk and its unique design will stand proudly out against other office equipment. Not only is the Pom perfect for the charging of separate rechargeable batteries but it can also directly recharge mobile phones, MP3 players and PDAs via a USBcable. No longer will you feel the urge to hide your battery charge underneath your desk beside plug sockets and excess cables. It is so pleasing on the eye that this product makes battery charging less of a chore and more of a pleasure.
