The full review
Why every hub gets warm, and why this one is fine
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.
The switch to the 555
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.
What I liked
- Runs noticeably cooler than cheap hubs
- Anker build quality
- Full port layout for DeX/laptops
- Reliable over a year of travel
What to know
- Still gets warm, that's normal for any hub
- Not the cheapest option
- No SD-card slot on some variants
- Overkill if you only need one port
Common questions
Is it normal for USB-C hubs to get warm?
Yes, pushing video and power through a small hub always generates heat. The question is whether it gets alarmingly hot; the 555 stays reasonable.
Does it work with Samsung DeX?
Yes, it's been my DeX travel setup for about a year.
