I just ordered two.  That should work for my phone, Kindle, and battery

Whoa, hold up a minute there. You do realize that they are only for 5v USB 
devices, like phones?

A 5v output can't charge your 7.4v Leica batteries. I suspect there are similar 
devices for camera batteries.

Also, there's no free lunch; you can't stuff more power into a smaller package using the same battery tech. Your Leica batteries M8/M batteries are 1860 mAh and the M 240 1800 mAh.

Average that to 1830, lose a few % for exaggerated claims, losses in transfer, etc. and you can probably count on about five full charges from an 11000 mAh auxiliary battery - IF it is a different one that works with your batteries.
