A finalist at the Greener Gadgets Design Competition, this battery tower looks to be pretty convenient. The main problem with conventional battery chargers is that they often take up valuable outlet space. This design incorporates a much smaller downward plug that will free up much need outlets for other appliances.
Also acting like a straw dispenser, the charging tower stacks batteries from the top to bottom and charges them accordingly. Let’s hope this design has some auto shut off features as well.
