One = Two battery

The One = Two is an innovative battery concept designed by Huang Kun, Meng Xun, He Ting & Liu Yuan, that provides a great way to use every last drop of power from each battery.

One = Two battery



The idea, already a 2011 red dot design concept winning entry, behind the spring batteries is that when two batteries become drained enough that they are unable to power your electronic device, they can be compressed and combined into one battery slot.

When the two batteries become one, then you can use every last drop of power before replacing with a new fully charged one.
