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.

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.

Love this USB hub, I like that each port has a switch so you don't have to unplug things you don't want connected. I like the ring light around each port. It let's you know where the port is in the dark and if the part is active, helpful with troubleshooting too. Mine came with a 3 Amp power adapter that works great for higher load devices and phone charging. I like that the phone charge port doesn't connect my phone to the computer (data-wise) so I don't have to deal with a connection popup on my computer. Overall a very nice hub.

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.

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.

Refer to website for pictures. This powered 7-port USB Hub 3.0 really works with USB thumb drives, SanDisk SSDs and Seagate high capacity 5TB portable hard drives. I connected to one wireless mouse and 3 5TB hard drives. The mouse moves smoothly and the contents of 5TB hard drives are accessible and display clearly. It serves as an extended USB 3.0 Hub flawlessly. The added external power to the USB hub really made the difference. My new laptop only came with one power input USB type-C port, one USB type-A port and one USB type-C port. This multi-USB port hub really makes up the deficiency of the new, thinner laptops. The only drawback of this USB hub is that the LED indicator light for each port is too bright and becomes annoying sometimes.

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.

I bought it to connect my sim racing kit, it works perfect, no lag

Pros: Works as planned Set it up one time and never have to do it again Useful when plugging in extra USB when the PC or Mac has limited USB ports USB 3.0 - Faster data speeds Will power devices from computers USB port. Doesn't need power supply One device for all my USB needs. Cons: - Power Supply broke after almost 4 years of use. So when I removed the cable my computer all devices needing usb power (i.e. desklight, fan, charging of headset) stopped working. Need to purchase a new one. - Only one Power Port. For me, I want more USB power ports to use with my phone, tablet, fan, light, headset or other devices needing power. Overall a solid 4.5. I loved how simple it is and how it kept my desk cleared from USB electrical power plugs
