We love design concepts here ate Geeky Gadgets, the latest one seems like a great idea, the Rubiks Cube Mobile Phone Charger.
The Rubiks Cube Mobile Phone Charger is the work of designer Zheng Weixi, and it seems like a simple yet clever idea. Inside the Rubik’s cube there is a small manual electric battery that gets recharged when you twist the cube.
You can then plug the Rubiks Cube Mobile Phone Charger into your mobile phone or any other gadget via USB and it will charge them up.
It seems like a great concept, although I am not sure how well it would work in practice.
