Idea – Digital Cameras And Powerbanks?

Cameras has batteries that don’t last that long. So why could not the camera be powered with an external powerbank battery?

This little Canon camera has a 680mAh at 3.6V battery. It could easily be powered by a powerbank with 5000mAh worth of energy.

With such a capability I would not need to keep the battery charged up before the trip and 5000/680 = 7 times longer videos could be recorded.

Should there not exist digital compact cameras adapted for this?

Idea – Digital Cameras And Powerbanks? Now this camera did not support this feature.
