Powered USB 3.2 Hub, ACASIS 16 Ports USB 3.2 Hub with 10Gbps Data Speed，Aluminum Housing, USB Hub Powered with 96W Power Adapter, USB Hub for PC/Laptop, Computer, Flash Drive, Printer, Camera

When you computer doesn't have enough physical USB ports any more, this hub is the way to go. I like the fact that each port is switchable, so you only use it when you need it. Plug in an external drive, switch that port on the hub on, back up your files, then switch the port off until your next backup. Another plus is that each port has a light next to the switch so that it's easy to tell which are on and which are off. I've bought two of these before and they're still going strong after 5 to 10 years or so.

11 USB devices were connected to the back of my computer. Now there's only one USBC cable. It's powering everything from the typical keyboard and mouse to a USB DAC, air quality monitor, desk fan, and desk lamp. No issues and it reduced the cables coming out of the back of my computer from 14 down to 4. Just used a couple of velcro command strips on the bottom of it to mount it to the bottom of my desk. Did the same thing to mount the power supply to the bottom of my desk.

I am not geeky enough to tell you how fast a USB hub allows data transfer. All I can tell you is that I like being able to connect all my external hard drives, printer, and scanner, and to be able to use push-button switches to isolate the ones I am not using at the moment. I have been using this for several months now, and (knock on wood) I have not had any switch failures.The only possible improvement I can think of for this device (for MY purposes, anyway) would be to make the pilot light next to each switch just a TINY bit larger. They are so small that it is sometimes a little difficult to see which ones are on or off; but that is a small detail, and it doesn't drive me any battier than I was already.

I had another USB hub were the blue lights were too bright so sent back to Amazon for refund. Most of the USB hubs had complaints of the blue lights being too bright. It took a while to find this USB hub with no bad reviews for the lights being too bright and good reviews overall.The switch lights are dim when looking from an angle. When looking from above the lights are bright without being too bright. The lights would be easier to see if red. I have another USB hub with a dim red light on the switches but is easier to see from an angle and in a bright room. The blue light on the power supply is bright. It is on the floor away from me so that’s OK. It is good quality aluminum housing. The on off buttons to turn on each port works well. The USB and power cable are good length and quality. Everything works good so far except when I tried to charge 2 android smart phones the charging current is too low.The description on Amazon says each USB fast charging port of the multi USB Hub can deliver up to 2.1A of current. I have a Samsung Galaxy A14 5G smart phone I bough about 7 months ago. I have a USB power meter to measure charging current and voltage. With the power supply plugged into the hub the USB power meter reads 5.04 volts on USB ports. I tried several USB ports to charge The Samsung Galaxy A14 5G phone with 31% battery charge left and the charging current is only .42 amps with phone turned on or off. Phone has fast charge turned on. Only one other ports is turned on for the wireless mouse. I also tried to charge an Android VIEW 3 Smartphone turned on and off and the charging current was only .42 amps also.I have a APC P12U2 surge protector that has 2 USB charging ports with max of 2.4 amps which says Smart Charging recognizes your devices and maximizes charging speed. When I connect the Samsung A14 5G smart phone into one of these ports the charging current is 1.18 amps and 5.13 volts on USB power meter. I charged an air duster on the USB hub and the USB power meter reads 2 amps charging current like it should so the power supply must be good. The charging current is just too low for my android smartphones. Maybe the charging current is higher on an iphone but don’t have one. These reviews on amazon say: This Hub is fast to charge my iPhone, it won’t charge a phone, Great hub but not for fast charging cell phones.Their should be a chip in the USB hub that communicates with the phone to negotiate the appropriate charging current a process called "handshaking” which i believe this hub doesn't have? I don't see a description on Amazon that specifically says it will smart charge a cell phone.Today on Amazon page for this model I noticed when you scroll down a little on the left side it says there is a newer model of this item. The description says smart charging 4 USB A Smart Charging ports only. Charging ports DO NOT support data transfer.I wanted 16 ports for data transfer so would not have bought this model but would fast charge a cell phone. If you want fast charging for cell phone the USB hub must say SMART CHARGING.Didn’t buy it to also charge my smartphone so not a deal breaker. I just have to charge my android smart phones on my APC surge protector USB ports to get higher charging current. I am happy with this USB hub otherwise.

This hub is pretty bad. It does not have nearly the power capacity to saturate all the ports. Devices will be working, be switched off, and switched back on and will not be detected until I shut something off to get the power up to initialize.I literally feel like I'm on the Apollo 13 mission trying to figure out the order devices need to be powered on for them all the be detected. The hub is plugged into a USB 3.2 port on my tower.EDIT after initial review: So the manufacturer reached out to me after posting my review and gave me some more technical information about the hub. The hub allocates 25W of energy per group of 5 ports. I intended and was using this hub to power multiple external hard drives, a Blu-ray Writer, and Raspberry Pi.This would explain why ports would go dead in groups and not come back to life until I power cycled it.They also offered me a full refund. So based on that, I'm going to up my rating to 5 out of 5 stars just due to their outstanding customer service and addressing me with technical information and not just treating me like some dumb buyer. I would suggest however that they include this power distribution arrangement and limit in their item description. I've repurposed the hub to drive all my basic stuff, keyboard (and lighting), mouse mat, wireless mice and chargers, infrared Webcam, and 3-axis controller and moved the power hungry items to my motherboard. It powers all that stuff just fine. So all in all, I'm a satisfied customer and won't write off their products in the future, but will inquire whether my intended use is within their product's capabilities.

Great device, replaces 2 USB 2.0 hubs. It is much more compact and the leds lighting up let's you know which USB 3 are in use. And the ability to be USB 3 vs slower USB 2 allows me more ports to use at faster transfer speeds.
