Art last week Share Tweet Pin Share Japanese-based company Nendo has produced a charger that allows users to charge their phone’s power bank. Utilizing a swivel hinge and internal dynamo, Nendo’s Denqul charger can back up your smartphone’s power bank by swiveling the device vigorously for a couple minutes. The Denqul can charge smartphones as well by way of a conventional cable or pair it with the table-top cup set it comes with for wireless charging. The table-top dock functions as a container for charging phones, as well as storage for glasses or stationaries so the mobile battery can be naturally charged as the day goes by.
