Anecdotally I've had a lot of problems with Anker products over the years. On two separate occasions my power banks died while I was travelling. I had a few Ravpower products that were at least as good. And now Ugreen seems to be producing good stuff.
I don't think there is any stickiness here, and it's a cutthroat market. These things are all at a price point where there will never be a winner-takes-all.
That's very surprising... Between me and my partner we've gone through 4 of these over the last 10 years. One was lost to airport security, another (the first) just became too slow with newer phones. The other two still work perfectly fine.
Maybe they last for us because we're not heavy users? We only use them on vacations.
same here regarding Anker powerbanks, and the bluetooth earbuds I got from them have all been disappointing: bad bluetooth compatibility, and waterproof levels far worse than advertised. I have had good luck with their chargers though, so still buy those.
