Perfect accessory for adding devices to the Mac Mini. It works perfectly and is sleek and esthetically pleasing to the eye. The unit is compatible with my machine and the price point is a huge plus. It has several ports for my older USB devices which is what I was looking for. Read more

Nice and compact hub, easy to slip into a pocket or small space. Also like that there's an indicator light for when power is on, that's useful. Nifty that there's two choices of power cord length, too - either the 6" or 2' length; one choice might be good for some, but not all. Appears to be solidly built and durable, so it should be long-lasting. Read more

Unlike some of the other USB-C expanders I've got here, this one is just a plastic case, not aluminum like it looks in the picture. The plastic is a tad "creaky" when squeezed but it seems decently built and I don't really expect any problems in practice with it. And as the product description does say and other reviews point out, the USB-C power input on this is just to make it work a bit more like a "powered hub" (e.g. for hard disks and such) and does NOT charge the laptop. So this isn't a premium adapter by any means, but they didn't charge a premium either. It's working well just to give some more ports from a laptop where I'm often running out. I sometimes use laptop stands above the devices I'm programming/troubleshooting on my workbench, and so the option for a bit longer cable is great. Reports as a USB3.1 hub (vendor 0x05e3, product 0x0626) and a USB2.1 hub (same vendor, product 0x0610) and nothing else when plugged into a MBP and so far so good using it. Read more

This works great, I'm using a keyboard, controller and a mouse on this hub. I tried using it with my headset, but it seems like even a powered hub isn't enough to share multiple ports with an audio device (mic, headset, speakers). I ended up hooking up the headset to the laptop and the rest of devices to the hub. Read more

This docking station provides completely solid support for multiple monitors for your modern laptop that has one or two thunderbolt ports and maybe a legacy USB A port. Simply plug your laptop's power brick into the docking station, plug one or two monitors in via the two HDMI ports, plug the USB C cable that comes with the device into a thunderbolt port on your laptop and that's it!! Immediately my 2 4k monitors displayed glorious color!! And this gizmo costs only $37! When I compare this to Plugable, CalDigit etc. for $250 and up, that price is essentially free. In addition my experience with the pricier devices is that reliability of the monitors is sometimes not solid - occasional screen dropouts for a second or two, monitor going offline, etc. I'm still astonished that this thing just worked right out of the box. Easily worth more than 5 stars. Support for other ports is weak. It does have a 1 gb Ethernet port, but no extra USB A or C ports, no sd card reader support, and so on. I bought a USB A hub for my legacy devices and that works well. Other resellers, including Targus, sell this for about $100. I have no idea how Amazon can sell this so cheap. In summary you if you need a docking station that has a zillion ports look elsewhere. If your primary need is dual monitor support this is an amazing bargain. Read more

If you have power-hungry USB devices but don't want a self‑powered hub with a bulky AC brick, this is the solution. Exactly what I was looking for. Works perfectly with my external disc drive, which would otherwise stop working when connected directly to my PC’s USB port due to insufficient power. By default, the hub uses bus power from the PC. However, when you connect a 5V phone charger to the auxiliary 5V-in port, it seamlessly switches to using external power. Most importantly, it correctly handles the power isolation, meaning your phone charger won't backfeed into your PC motherboard, or vice versa. Here is some experiments I did: 1. Open-circuit voltages: PC USB port = 5.17 V Phone charger = 5.04 V 2. Connected to PC only: 2a) No device on hub: hub port voltage = 5.17 V; PC current draw = 39 mA. 2b) With ~100 mA device on hub: PC current draw = 137 mA. 3. Connected to both PC and phone charger: 3a) No device on hub: hub port voltage = 4.99 V; PC current draw = 2.1 mA. 3b) Connect a device (~100 mA) to the hub: PC current draw = 2.5 mA. Read more

Item does work but not as described. The powered only supplies power to the usb ports and not to the usb-c cord on the hub. Also, the hub ports are not all connected, if something is plugged into a usb hub port and you plug a usb drive into another hub port it will not recognize the drive on the device. Read more
