Using a external battery to power a digital camera?


I’m wanting to get this cannon 16.1 mega pixel camera with 1080p video and needed to know if I can power it via external battery through usb. I’ve got a anker 10000mah one that works fine with my droid 4 and I can use it while the anker battery charges it. But I just need to know if I can do the same with cannon digital cameras? Or what camera would I need to use?

The one I want to get is the Cannon Power Shot Digital ELPH 110 HS.


I’m not sure that it’s part of the spec, but most USB devices will work just using the connector as a 5V power plug. (Many will happily draw more than the 500mA that they can pull from ‘real’ USB connections too.)
