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!

The one thing I will say - which is just a guess - that I think this is being discounted because Anker is moving to the Anker Prime 27 [anker.com], which also has the charging base option [anker.com]. The Prime 27 is 27,650mAh, and weighs slightly more and is slightly larger. It costs more, as does the base option.
That wouldn't stop me from grabbing this deal though.
on the go no issues

But you need to know how long in order to calculate how much each charge takes.
As an hypotethical example, 120W x 1 hour = 120Wh. Then, this power bank will provide about 88% assuming 100% efficiency.

160Wh is the limit
So 27.65Ah x 3.7V = 102.305Wh
160Wh is the limit
So 27.65Ah x 3.7V = 102.305Wh
160Wh is the limit
So 27.65Ah x 3.7V = 102.305Wh
99.54Wh ÷ 24Ah = 4.1475V which is an odd voltage
The voltage is depends on the batteries inside. 3.7V is nominal for 18650 batteries which are widely used.
