Powered USB Hub 3.0, Atolla 7-Port USB Data Hub Splitter with One Smart Charging Port and Individual On/Off Switches and 5V/4A Power Adapter USB Extension for MacBook, Mac Pro/Mini and More.

Plug & Play ready, no software or anything to install. Works great, long enough power cord & USB-C cable, strong and fast connection. Only issue, and this is on me for not paying attention, is that my PC is setup to put the external drives (what I use the Hub for) to sleep when not active, and to power them off when the PC powers down. The Hub having it's own power source doesn't power them down with the PC and I have to manually turn it off. Maybe there is a way to configure it, but I've only had it a few days so I haven't messed with it yet.

I had so many peripherals connected to my PC Tower/Server that it would freeze on boot-up. I also had a USB line connected to a large safe for the data storage drives located inside the safe. After some research, I ordered two of these highly rated, Atolla, powered hubs. I removed all of the USB connections from the PC Tower/Server and connected everything directly to this self powered USB hub. I then connected the input of this self powered USB hub, to the USB connection on the PC Tower/Server. I placed the second of these Atolla, powered hubs inside our safe. There, it presently powers three data storage drives and allows for future expansion. This solved all of my USB problems with virtually no power drain on the system’s internal USB ports. This hub will work without plugging in the included wall-wart, power supply. However the added power boost of the AC connection makes everything work better. The individual power switches on each USB port is a great feature. One can turn off the unused ports. I can only see 2 negatives in the design. I wish that it had an in-line power supply with a regular electric cord. The included wall-wart, power supply is large and difficult to plug in to a power strip with other items. I also wish that the hub would automatically shut off when the computer is turned off and/or when there is no USB signal feeding the hub. In self powered mode, it stays on 24/7, which translates in to your USB peripherals being continually powered. Over all, this a great product. It is a major upgrade to any computer. Update: After using these self-powered hubs for a while, I would offer a tip. They do a great job but when using more than one hub connected directly to the same computer, I had a little glitch on boot-up. The problem was eliminated by feeding the second, self powered hub, from one of the USB ports on the first self powered hub. (daisy-chained) This worked much better than having both hubs connected directly to the same computer.

I've had a smaller version of this Atolla for years. I purchased a new NAS device that I needed to add external hard drives to, so I relegated the older smaller edition to the NAS and now have more ports on my Dell OptiPlex PC. Works great and I finally have enough USB ports to keep all my cords connected. It is a good value and seems to run fast like the original one. I also like the extra fast charging port that I use to charge my Garmin (and other things). Works with all my devices.

Worked great for 2.5 years. Added 7 USB3 ports to my PC. Seems like everything is USB so I needed extra ports. Sadly, about 6 months ago, USB 3 devices stopped working. They powered up, but no communication. USB 2 devices though, still work, so I suppose it is the internal circuitry. I checked the port it was plugged into on the computer to be sure it was USB 3, and changed to another USB 3 port, but still no USB functionality in the device. I noticed this first when a High quality, 256g USB3 thumb drive quit working. It still worked in a USB 2 port, but had all sorts of errors on the USB3 port. I believe this hub damaged the circuitry in the thumb drive. It no longer works on any USB 3 port, then stopped working on USB2. Then I noticed that none of my USB 3 devices worked on this hub. So I have no proof, but I believe this hub's internal circuitry failed and damaged my thumb drive. So disappointed, because until this incident, this was a great hub. Heavy wiring, came with power supply, worked flawlessly until it didn't. I am considering replacing it with this same model, but not sure. I have 10 year old USB 2 hubs still working well, and I don't know if this brand is an issue, or maybe similar brands have the same chipset and prone to the same issues. If you ask me a year ago, I would of been 5 stars and a hearty recommendation. BTW, the hub is on a UPS system and surge protected. The port it was connected to is on the motherboard, and the port is fine. So it did not damage my PC or port. Since I use a lot of USB 3 devices now, I am going to remove this, as using it as a USB 2 hub is not useful.

This is a great device that'll be sure to keep your USB portable devices up and running. (Just be sure to unplug, when not in use.

muy util compre una laptop y solo tiene 2 puertos usb con este articulo puedo conectar cualquier accesorio hasta disco duro

Working very well.

I have two ,all are working good . No problem.
