HandEnergy is an ingenious apple-sized device that charges your phone anytime, anywhere. But what really makes this thing special is the fact that it uses your own personal energy to do it.
HandEnergy是一款苹果大小的天才产品，能让你随时随地为手机充电。然而，这款产品真正的独特之处在于：它能运用你自己的能量充电。
In a time where power-banks and solar-power devices have become mainstream, a device that lets you charge gadgets on the go doesn't sound very special. But while power-banks have to be charged the old fashioned way, and solar panels need the sun to store energy, HandEnergy just needs a hand. To get this little guy to produce energy, which it then stores in built-in batteries, all you have to do is hold it in your hand and rotate your wrists.
在一个移动电源和太阳能电源已成为主流的时代，一款能让你随时随处充电的设备听起来并没有什么特别的。但是，移动电源必须用传统方式充电，太阳能电池板需要太阳来储蓄能量，而HandEnergy只要一只手就够了。要让这个小玩意儿产生能量并将其储藏在内置电池中，你只需要把它握在手中并转转手腕就可以了。
To use HandEnergy, users start by winding a starter ring. This transmits a signal to activate the rotor, at which point they can start rotating their wrists to keep the rotor spinning. It might sound hard to believe, but the rotor inside HandEnergy spins at an average speed of 5,000 rotations per minute, transmitting mechanical power to create an electric current, and charging the built-in batteries. To charge a device, all you have to do is hook it up to HandEnergy using a USB cable.
要想使用HandEnergy，用户一开始要先缠启动绳。这个动作会发出一个信号激活转子，然后他们就可以旋转手腕让转子转下去了。可能听起来难以置信，但是HandEnergy内部的转子能以每分钟5000转的平均速度旋转，将机械能转化为电流，为内置电池充电。想为设备充电时，你只需用一根USB线将其与HandEnergy连接即可。
HandEnergy was successfully crowdfunded on Kickstarter, raising over $71,000 in one month, and will be available for the masses in May 2017, at a price of 99 euros. One thing is for sure – it beats paying thousands of dollars on a solar-powered gadget-charging coat.
HandEnergy已经成功地在Kickstarter网站上发起众筹，并在一个月的时间内筹集到了超过71000美元，可以在2017年5月批量生产，售价99欧元。有一点很确定——它比花几千美元买一个太阳能充电套强多了。
