Power USB Hub 3.0, atolla 16 Port USB Splitter with 12V/6A Power Adapter and Individual Switches, High-Speed Data Transfer for Laptop, PC, Mac, and More Devices

I love it! Each one can be turned on or off.

Easy to use. Just plug it in and plug in usb hard drives and it started working immediately.

I like that I can turn off individual ports. I only wish it had a master on/off to disable all.

Perfect as a stand alone power port.

I filled all 16 slots with devices, mostly usb sticks and spinning disks, but also things like keyboard, mouse, usb desk lamp, camera battery charger, and CD-ROM drive. For a few weeks, this worked great. Then one day the whole computer froze up and stayed frozen. A cold reboot (unplug, replug) and the OS wouldn't come up. So I unplugged this hub, plugged the keyboard and mouse directly into the computer. Booted fine. Removed all devices from the hub, plugged in the hub, and no problem. So I plugged in every device into the slot it had been in, one by one, to see which one was the problem. They all worked!Today, similar story- frozen computer. A cold reboot worked, and I could enable every slot in this hub to see what didn't show up. Turns out a 5TB spinning disk drive had vanished. So I removed that drive from the hub and plugged it into the computer directly. It worked fine. So I stuck it back into the hub, and it still worked fine, but a stick in another slot vanished. I tried moving devices around to see if the failure followed the device or the slot, but nothing failed again. So I'm back to the original configuration, everything works fine, and we'll see what the failure mode is next time. This hub has intermittent issues.ETA: Rebooting the computer turns out to be overkill. In Edge file manager, under This PC, look at the attached devices. One is generally missing. Press the off button for that connector, wait a couple seconds, press it back on. And there is the drive! It's nearly always the 5TB drive, so there might be some compatibility issue there.

Ok, no computer I've ever owned has had enough ports on it to hook everything up in one go. Usually, you have to unplug something to plug in a different device. We'll, when you're running lasers, 3d printers and standard printers plus mouse, keyboard and a web cam, you need way more ports. This, has worked beautifully for exactly that. It allows my computer to interact with everything I plug into it so I don't have to unplug anything. It's a real time saver.

I need all these usb hubs for some of the work I do. The thing I like most is that I can turn the unused ports off.

16-port USB Hub. It has had rigorous use since I received it. Used near daily.I also have a few smaller hubs (4-port and 7-port) of this brand and they are also holding up perfectlyThis is just what I needed to plug in all of my backup flash drives and external drives at the same time to run all my backups at once instead of only two drives at a time. It has saved me over an hour each time I backup files.
