Equipment that can generate electricity by shaking: HandEnergy

For outdoor enthusiasts, a walk away trip certainly requires a complete set of equipment. Although it is far away from electronic products and social networks, what problems will happen in the future should not make mobile phones without power.

There is no need to mention the power bank. Brother Ganji has introduced a lot of solar charging equipment to everyone before, but in case of a cloudy day or night when the mobile phone loses power, solar charging seems to be useless.

Brother Ganji introduces another charging device today: HandEnergy , shake it and you can charge it!

The appearance of HandEnergy is a small ball, which looks different from other charging devices. You just need to connect the device that needs to be charged with a data cable to HandEnergy, and then shake it with your hand, and power will come!

In fact, the principle is very simple. HandEnergy contains a small magnetic rotor generator with a speed of 5000RPM. Through some ingenious designs, it converts the shaking mechanical power into current to charge the built-in battery.

From the appearance, HandEnergy is very mini, weighing only 380g, 70.7 * 72.8mm, with a built-in 1000mAh lithium battery. It looks lovely.

HandEnergy can provide 5V1A power output. However, compared with traditional chargers, the charging efficiency of HandEnergy will certainly be slower, but this is not a big problem.

Compared with other charging products, HandEnergy's independence is its biggest advantage. Because the power bank must take a long time to charge to ensure power, while the solar charger needs the sun to provide energy. HandEnergy can charge itself only by providing kinetic energy, which is necessary for emergency use.

Of course, like solar energy, HandEnergy is an environmentally friendly product that will not cause any pollution to the environment.

At present, HandEnergy is crowdfunding on Kickstarter. The price of Early Bird is 69 Euros (about 500 yuan), and it will be officially delivered in May 2017.
