All the data including Watt/hour is on the bottom of the power bank. All power banks are suppose to be properly label so TSA can take a quick look. But technically I guess you can fake it... Some places like Chinese airlines are very strict. No label on a powerbank = throw away.

Just make sure there isn't a little green dot in the upper left corner. That will slowly drain the battery since it's on trickle charge mode. I had to Google how to get it off since the instructions are so vague.
I'm about to send my 2nd one back for the same reason that I exchanged the 1st one. IDK if it's a design flaw, but what are the odds that I received two duds in a row?
The problem is that it loses a lot of power while it sits. After being fully charged, it shows that it has only 61% charge remaining after sitting for less than two weeks. And yes, this is with it fully OFF. They were not in "low power" charging mode, and no cables were attached to potentially trigger it. So there's no reason for it (them) to dissipate energy like that.
QUESTION: Has anyone else had this same type of experience with it?
Also, if you use a current metering device between the wall charger and the Anker, current continues to flow into the Anker even after the Anker's meter shows 100% charge. So there's some inaccuracy there too.
Other than that, it has a lot going for it. Super fast charging when using a high-output charger. (Although that will wear on the batteries more than if you charge it more slowly.) Great compatibility with a wide variety of equipment. I'd love to keep it, but I need something that will be available in an emergency (after sitting unused) and this ain't it!
