I bought myself an anker powerbank because of all the rave around them. Mine behaves incredibly strange. Charged in seconds, then not containing half a phone charge. For a 20.000 mAh this was really disappointing. Probably a one of but still leaves the impression that this was looked at because it ruined the price for others.

That's obviously a dud cell. Contact support if it's not several years old.

Had a tangential issue with an Anker power bank (screen was sometimes showing bogus charge essentially), and can confirm Anker E-Mail support is pretty good in my experience, they sent me a second unit (even though the first is still functional and I still use it just fine to this day), free of charge after a brief exchange.

Might be worth a shot.
