The apparently internal PSU is a nice touch.
A lot of ‘USB Chargers’ are suspiciously similar to USB hubs; just with the ‘hub’ options either nonexistent or deeply unloved; but still reliant on a huge, ghastly, wall wart of limited trustworthiness.
If you actually have enough power-only USB devices in your life to be in the market for something that delivers power without data; you might as well at least skip the wall wart. And make it rack mountable; with SNMP monitoring… Um… where was I?
