Sorry for reviving a necrothread again but I am really bored today. I have a couple of these (latest version) and have tested them extensively. I find them to consistently be about 1/10th the capacity they claim and essentially useless. I have switched to simple battery I am linking below and find it lets me charge my phone multiple times on a typical expedition. (My phone is also my camera...)

I must be bored also. I am charging some 18650’s to measure their capacity. As far as the 100AH batteries I stated earlier in this post that was 6 times the power density of the best batteries on the market. Any good electronic engineer could figure that out.

I usually use battery backup as Pisen Portable Power 10000 mAh for my smartphone (also my camera)
