Now the problem of cellphone batteries that are quickly used up can be overcome by power bank technology. However, these portable battery devices still have limited durability. The bank's power must be recharged by plugging in the power adapter. However, along with the times, there are technology companies that make power banks unique.
The Japanese technology company, Nendo, made a power bank that was refilled by playing it. The unique power bank specifically designed to be used in emergency conditions was named Denqul.
Quoted from the Hype Beast on Wednesday (11/28), Denqul's power bank was designed specifically because it could still be recharged without any electricity source. Denqul is a tube with a small diameter. At a glance, this power bank looks like a small stick.
However, this device can store electricity with a capacity of up to 5,000 mAh. The power capacity is enough to double charge the smartphone to full.
Denqul's power bank can be extended like a selfie stick. The end can be bent 90 degrees to form a rotating crank. Well, in the part of the power bank there is a generator that functions to convert the force into electrical energy.
To turn the crank, the user only needs to hold the end of the power bank. Later, the bent crank will rotate like a propeller. Well, that turnover produces the energy and resources that are stored.
Not only played, the power of the Denqul bank can also be charged with electricity. Although it is very interesting, it is a pity that it is not clear how much the bank's power price is. Also not explained is how long the bank's power endurance.
