RE: USB batteries
I have been using these for a few years and agree they work very well. I did some limited capacity testing to compare them to good quality alkaline batteries. The short story is they have about 75% of the capacity of an alkaline cell. The link to the video I did on this is below.

These cells tend to have two types: 1) Have micro-USB connector on side of cell, 2) No connector. I prefer the second type which are charged by placing 5V across the cell. The build in charge controller takes care of things. The downside is that you need a little 'dock' to plug the batteries into. The dock plugs into a 'USB' power source.
