Huh, I haven't had issues at all. I have a USB hub with 100W PD and HDMI, and it's been working fine for almost 3 years now on my MacBook. I also have a battery bank from them and it's fine, though I've only used it like 3-4 times over the few years I've had it (just use it for travel as a backup plan). I recently got A surge protector/power strip thing from them as well (pretty recent, like 2 months).

I went with them because of good reviews on Reddit and tech review sites, and the few low reviews on Amazon were easy to chalk up to random QC issues (every product will have some bad ones ship), but the customer support seemed decent from the reviews I read.

Have you ruled out bad cables and your Dell sucking?

I think I'll look up some tear downs next time though. Good brands can absolutely go bad, so it would be good to see if that has happened here. Unfortunately, the charger landscape is mostly full of Chinese crap that I don't expect to work properly on day 1, much less after a year or two.
