Powered USB 3 2 Hub ACASIS 16 Ports USB 3 2 Hub with 10Gbps Data Speed Aluminum Housing

The device appears to work well. I would have liked to mount it on the wall but it has no mounting hardware. This is not uncommon so it isn't that it's bad in any way. Many don't have a way to mount it. Some double sided tape will work but I would have liked some lugs with screw holes on the ends to accommodate the mount. The connecting wire (usb-a to usb-b) would be nice if it was just a bit longer but it just reaches the connection on the back of my computer so it will work as well, just a little tight. Overall it did increase my speed of transfer from the previous one I had which was quite a bit older so that is a good thing. The power supply is fine but could have used the wire-block-wire method instead of the plug in block. I had to shift around some items on my power management block to find a place to plug it in without blocking other outlets but I got it worked out. It is in a metal case so it should be very durable and hold up under pressure. I could recommend this device if you are in need of such a thing. Read more

I have 5 4-Disk RAID-5 arrays that I attach via USB-A connectors. This is the third USB 3.2 Hub I've tried. The other 2 had problems with the arrays disconnecting, often while copying files. This one, however, is working great and is rock solid. My older PCIe 5-port USB 3.0 adapter was starting to feel slow, so I figured I'd switch to an external hub to make it easier to replace, and get a USB 3.2 hub for faster transfers. I've copied about 30GB of files to the arrays so far, and I've had no disconnects with this hub. I have a large transfer of a few terabytes to do from one of the arrays to another, but I haven't done it yet. I'll update this post after I do that transfer. Read more

Works well. The ports are confirmed usb 3.2 capable. I had transfer rates of 750 mb/s. It also functioned properly with out any extra tinkering with my PC. So far its powering my external SSD just fine, in addition to my other things. Read more

Very useful for people who have lots of power hungry peripherals. As a gamer I have a lot of different devices connected to my pc and every once in a while I had either disconnects or an unresponsive device, now that I put this into place I no longer have this issue! Read more

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. Read more

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. Read more

Seems to be working well. Very good weight and feel to the product. I feel like I made the right choice. Read more
