I have removed Anker 10-porter from the list, as it is discontinued, leaving only 9+1 version in.
Looks like the AC adapters are starting to feel the heat (literally) of a 24/7 loaded run. I had one AC adapter of my 10 D-Links fail tonight, but the power supply from the master hub (ST-Link handled that gracefully and kept the rest of the hubs running with a reduced number of BEs).
I opened the failed adapter, but cannot see any damage inside:

It simply did not deliver any power out. Maybe the transformer coils burned out...
Anyway, I salvaged the cable with the barrel plug and connected it to a Molex splitter. I'll attempt loading it with 7 BEs running off PC PSU. Or maybe I'll use it as a master hub.
