Thanks for the good ideas. Here's what I've got:

1. The back of LCD says 7.4V. I can't find any other electrical specs on it.

2. The CA-PS700 AC adapter says the output is 7.2V / 2.0A. This is 14.4 watts.

3. The LP-E17 battery says output is 7.2V and 1040 mAh. I found 7.5 Wh on the opposite side of the battery. This makes sense because 7.2V x 1.04 Ah = 7.5 Wh. I can't find any indication of an amperage limit though.

4. Knowing all this, I searched the Canon M6ii User Manual again and found nothing. There are apparently no specs in the manual.

I went ahead and ordered the USB battery power cord from Amazon and will try it with the standard 5V / 2.4A USB battery that I have. That is only 10.8 watts, so am not sure its going to work. Will just have to try it and if it doesn't work, then look for a USB battery with a higher amperage rating.

Let me know if I'm missing something obvious!


I have the adapter you linked to above. It works fine with standard 2.4 amp USB battery banks. However I haven’t done any extended shooting (like for hours on end) with the setup powering my M6ii.  I have however used it to power my M6 for an hour and a half while shooting video continuously (with momentary pauses at each half hour to restart recording of course).

I do recall reading that the camera may time out after a while though (regardless of power status). Maybe do a search for this.
