Recharging batteries makes it possible to live without constantly shopping for batteries. However, in reality those dinky chargers are inconvenient and hog precious outlet space. Which is a serious crime in my house that seems to have a single outlet per room. Well this design will only cover up one outlet and it will work with multiple battery sizes.
Sure there are plenty of wall chargers that will charge more than one size, but they are usually awkward to get them all to fit. Plus they only charge a few at a time. This one you just drop the battery down the middle and it’ll sort the battery out itself. Currently this battery station is entered in the Greener Gadgets Design Competition and is a finalist. That unfortunately means that it’s a long way from the production line.
