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

Great to use and works perfectly

Pros: 5.11v power consistent to all ports Full-speed to devices Power off or Power on each port without removing the device Light indicating power or off for each port Long cord to the power supply and long cord from the power supply Cons: Nothing of note Item of Note: Speed will depend on how fast your device (e.g., USB stick) and how many devices are in active use, meaning how much data is being sent/received at the same time. Wow, this thing is a good foot long and looks great. Measured port power didnt fluctuate even with unpowered hard drives (like a WD passport) being connected) in addition to USB flash drives. File transfer speed was at full rated speed and was the same as if I had the drive directly connected. I tested with a very fast drive and a slow drive at the same time, as well as two similar normal USB 3.0 drives. I transferred data simultaneously without issue. Speed did vary as the full bandwidth of the computers USB port was shared among the devices. This comes with a 12v power supply, which has a long power cord to the supply and another long power cord, ending in a barrel connection for connecting to the hub. This should provide plenty of length for you to place it where need, although it will require being within 3-feet of your computers USB port due to the length of the connector. The connector is a thick USB 3 cable with at Type-A male end. Each port lights up in blue. If a device is in the port, you can press an individual button to turn off the device and it will disconnect from the system. Likewise, you can turn it back on again using the same method. Bottom Line: If you have lots of drives, drives that you use but not all the time, and limited ports, this hub can handle it. Power off and back on without removal the device.

This is a powered USB 3.0 hub 3.0 with ports. Now that may seem like a simple sentence, but it isnt. In fact, USB hubs that claim to support USB 3.0 do not. The Atolla hub does. In addition it is powered. That mean that you need to plus it in. Many hub use what is called bus power. That mean that the power that they use is drawn fro the computer or device that they are connected to. That can put a strain on your system if you are using a lot of USB ports for power or charging. Having your own power supply for the hub is nice. Atolla claims that the hub delivers 12V/6A of power. My testing confirms that. Also Atolla clams USB 3.0 data transfer rates. Again, I have conformed that. So far, the Atolla is stacking up pretty well. Speaking of power, the 16 ports on the hub are individually switched. That can save money and heat. When you with a port off, the led light for the port also goes off so that you can visually determine if a port is on or not. That is nice. Atolla also claims fast charging speeds. While that is true, the Atolla does not support the latest quick charging standards. In the world of electronics, especially consumer electronics, a lot of manufacturers make all sorts of performance claim that they do not meet. Im happy that Atolla delivers what they promise.

Large like other reviews say. Love the 2 second power off switch x16.

Finally, we have a nice station to charge most of our devices in a single, central location. Im sure there are other hubs like this out there, but its my first. I like being able to switch on or off each USB port. I dont understand why items like this dont come with mounting hardware so it can easily be fixed in place, but I cant deduct stars from it since hardly any power strips or things like that come so equipped. Thats just my preference. Overall, a good buy.

I LOVE THIS THING! My laptop only has 2 ports and I need to have access to way more than that to run my programs. this hub is INCREDIBLE! The main board plugs into an outlet, so your computer isnt powering the big strip. you can turn on and off power to each hub. very nice

Wow. That pretty much sums up my initial reaction when I got this out of the box. This hub is just freaking huge (just over a foot long) and the 12/6A power supply is also large and quite heavy. The overall construction seems good and it seems to work well. Having the ability to easily add this many USB3 ports is quite nice in some situations, especially as they all should have a full power budget thanks to the large external power supply for the hub. For my own purposes, this is going to be a blessing for when I have to do an annual update of safety and training videos onto flash drives. I have typically been doing them in groups of four while watching TV in the evening, but being able to start 16 loading at once and then just come back and check on them is going to save me SO much hassle. Basically, this hub is massive and not for everyone, but if you need it, you need it, and this one should serve you well.

This was surprisingly large for a computer usb hub. It has 16 ports, each with its own individual power button and LED light to show if its active or not. The hub data link to usb-a port, is hardwired into the hub. A power supply with 12 volts/ 6 amps is provided in the box. This hub is great for people that dislike plugging and unplugging cables. Each port is capable of charging and data, so its a huge expansion perk for any computer.

I ordered this 16-port USB hub because I always have many devices to charge; such as cell phones, tablets, smart watches, headphones, portable batteries, and other things as well. I had been using a 3-port USB charger at my desk, but I was always having to unplug one device to charge another. With this hub I can leave the cables for all of the devices I charge on a regular basis plugged in, so that will save me a lot of time. Although this hub can also be connected to your computer and used to access flash drives or portable hard drives, my primary computer already has enough ports for those devices, so for me this hub will only be used for charging. The big complaint I have is the lack of USB-C support. This is 2023, not 2013. There is no excuse for any product like this that is being sold today to not have full support for USB-C. The main cable that is used to connect this hub to your computer should be USB-C, not USB-A. And at least half of the 16 ports should be USB-C. If Atolla would update this product to include those changes, I would give it 5 stars. But although this is a fine piece of hardware and it solves a big problem for me, I cant give it a perfect rating without USB-C support.

This is a lot larger than I was expecting, but its very nice to expand my USB3.0 ports. I like that it has individual on/off control for each port, and so far I have no complains. Speeds are good, and no connection issues or errors.
