StarTech.com 7-Port USB 3.0 Hub - 5Gbps - Metal Industrial USB-A Hub with ESD Protection & 350W Surge Protection - Din Rail Wall or Desk Mountable - TAA Compliant USB Expander Hub (ST7300USBME)

I recommend this item if you need a real industrial grade performance. This item comes without a power adapter, which makes the perfect sense to me. For general purpose it works without a power adapter as usual passive USB HUB. To take advantage of the surge protection of this item you need to power it up. As described in the technical details you may use DC power supply from 7V to 48V, which obviously makes a difference in the cost, so the customer can choose the right one. I specifically needed an industrial grade of performance, as previously I had about a dozen of USB HUBs, but even a best one of them still "kicks out" some connected devices when I connect a Dual-Dock with 2 14GB disks in it. I bought power supply (DC 48 V, 3.5 V, 120 W). Following instructions - it took 20 minutes to connect power to this item. I am using this item for the first day, very intensively. So far - even under the extreme conditions, utilizing all 7 ports, including the Dual-Dock with 2 x 3.5" disks - no "kick outs". I bought another (4-port) StarTech.com 4-Port USB 3.0 Hub - for my other PC. Both HUBs work at industrial grade performance.

Great quality, no issues with any of the attached usb devices attached. Consistently functioning as described. Would buy again.

Great product. Can't beat the price.

We have these on our telescope, and they have worked quite well. Of course we power them externally. After 3 years, of constant use in all weather, one broke. I am not sure why, but we just replaced it.

I bought this USB 3.0 hub for use with some astrophotography equipment. I have used it in all manner of conditions ranging down to temperatures as low as -15F and the high dew conditions of a Wisconsin summer which had water basically dripping on my equipment. It has handled all these conditions reliably and superbly - no other hub I've tried worked this well. One small flaw - the 12V DC power connection terminal on the hub doesn't hold on tightly enough to the wires; it is a connection where you tighten a screw to hold the wire in place. The wire has a tendency to slip out and periodically needs to be reinserted and screws tightened. Apart from this one flaw, I am really happy with this hub.

You need to take it apart and swap jumpers (see direction) in order to utilize an external power supply. Works perfectly at full utilization.

I have a test bench that uses a *lot* of USB based test equipment, and even with ESD mats and sprays, I always seemed to damage my USB 3 hubs with static discharges, or iffy units under test. I have used the StarTech USB 2.0 hardened hubs for years, and have yet to have a single failure. So, I added in one of their USB 3 units to the mix. It has worked flawlessly and the ability to run from just about any voltage source is a big plus.

Definitely the way to go if you are looking for a USB hub. Purchased multiple times and have had no issues with these units.

Works fine. Fast shipping.

I like the mounting options, the device is very solid and I bought the extra power supply (sold separately). The only con to me are the « loose » usb ports. It is normally not so easy to connect a usb port in reverse, but this hub allows inserting the usb in the wrong position. I mean, we shall all look before, but who never had multiple attempts while connecting a usb port before? Anyway, I would (and likely) buy this product again for any electronic manufacturing stations or lab desks.

Arrived with a rattle on the inside of the unit, for an industrial hub, the quality certainly is unexpected.

This is a very well made and specified Hub. I would suggest opening the case & changing the lower board jumper from bus to external power. This will allow the hub to be freed from the constraints of bus power to using the connected PSU power. A number of low powered devices on the bus would not connect (perhaps an overload from many devices) but since this has been done the operation has been flawless. It would have suited my purpose to have been slightly shorter as I was fitting the hub into a case but other than that I have no complaints.

I bought this Hub to power all my USB camera equipment for astronomy. So far, I've got 2 cameras, a filter wheel and a com port. That's a mixture of USB 2 and USB 3 devices. All plugged in and running nicely off this hub. The wide range of Input voltages means that I can power it from a leisure battery without having to worry about the exact voltage that I'm putting in. Expensive, but it's stable and seems to be reliable. (I can forget that it's there.) I'm planning on adding a USB GPS, and a USB hard drive at a later date. So 7 ports is perfect.
