All of the transformers plugged into your power sockets consume electricity, even when they aren't charging up your gadgets. That's why it's so important to find a way to manage them effectively, by unplugging them or by just turning off the power bar. But what if there was a better way?

The Leech Plug was invented by RISD studen Conor Klein. It's based upon the behavior of a leech, which will usually drop off a host once it has had its share of blood. This is actually what this power plug does. It physically disconnects itself from the plug once it's all charged up.

This is a great way to save money by reducing the amount of electricity that vampire transformers leech out of your power grid. This is a simple yet effective way of having the power plug disconnect from the socket.

It is hard to tell when electronics are or are not taking energy and many never stop taking energy if they are plugged in (e.g. cellphone chargers). This product solves that problem by using a timer circuit and electromechanics to eject its plug which disconnects your device from the wall outlet. once the plug falls out, all energy consumption stops and only resumes once the plug is inserted again.
