Here’s another conceptual yet innovative piece of work, the Crank Up Battery by Qian Jiang. This portable device acts as a power source for your rechargeable battery, in case you find yourself under a situation where’s there’s no available power source. Just simply put your rechargeable battery into this handy hand crank battery charger and start cranking. 5 minutes of cranking should give you about 45% of power. Definitely a brilliant concept!
