It is a technophile’s worst nightmare: being stranded away from home with no power outlet to charge a depleted gadget. Designers Haimo Bao, Hailong Piao, Yuancheng Liu & Xiameng Hu propose Continuance as a brilliantly simple solution to this dilemma.

Continuance is a line of rechargeable batteries with a powerful addition: a USB port on the side. The addition of a USB cord lets the stored power in the battery transfer to another location.

The USB plug allows users to charge gadgets when away from home – provided they can remember to slip one or two of the batteries into their pockets before leaving.

The concept, an iF Concept Design 2011 entry, is a clever answer to a common problem. It may need some further development before it can go into production, but when/if it does we’ll be first in line to take some home.
