I stick to Anker for cables, batteries and chargers. I'm sure they've had their own issues but everything I've bought feels well made. The only one I've had an issue with was a USB-C to everything else adaptor which weirdly stopped working after a week or two. I was surprised to find that their support was based in the UK (Cardiff if memory serves) and very efficiently processed a return and replacement.

I've watched Big Clive's videos for too long to trust no-name Chinese things with anything involving mains potential or energy storage.

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.
