Denqul Emergency Mobile Battery by Nendo for Sugita Ace

Denqul is a minimalist emergency mobile battery designed by Tokyo-based studio Nendo for Sugita Ace. The battery was designed specifically for disaster-use, and can be charged via a manual hand generator built directly into the device.

The designers wanted to create a powerbank that could be used both at home and on-the-go. In especially difficult situations, securing power for a smartphone could mean having access to basics such as communication, news, and lighting.

The unit also comes with a container that allows for storage of basic everyday items such as glasses and stationary. To activate the hand generator, the stick can be pulled out to double its size and bend to an L shape. The user can then swing the device with one hand to generate power using centrifugal force.
