Runs hot? They all do. But the Anker 555 runs a lot less hot than the cheap hub that scared me. A year of daily Samsung DeX travel use — same port layout, far better build quality.
I've run Samsung DeX as my travel setup for about a year, and here's the truth: every hub gets warm when you push video and power through something that small. That part is normal. The problem is when it gets too hot — my first cheap hub got to the "is this going to melt" stage.
I switched to the Anker 555 and it's noticeably better — still warm, but never alarming. It has the same kind of port layout I was already using, and Anker's build quality is honestly in a different league from the off-brand hubs.
Yes — pushing video and power through a small hub always generates heat. The question is whether it gets alarmingly hot; the 555 stays reasonable.
Yes — it's been my DeX travel setup for about a year.
