ACASIS Powered USB Hub,16 Ports USB 3.0 Data Hub, Individual On/Off Switches, 12V7.5A 90W Power Adapter, USB Hub 3.0 Splitter Extension for MacBook, Mac Pro/Mini, iMac, Surface Pro Laptop/PC

Must be unplugged for the Mac to boot up. Otherwise its OK.

This is the simplest, most effective multi-port USB hub available. Its easy to install, the cord lengths mean you wont have a multi-port hub dangling or hanging next to or behind your computer, and if you have multiple USB-connective external devices you cant be without this is the port hub to have. I only wish it was available a year before I finally found and bought it!

Nice product but the system connectors when using the HUB in the horizontal position (length wise) the buttons are behind the attached device wires making it difficult to reach.

Using it to feed data to multiple objects. No problems.

So maybe the lights arent the most important part but they sure are handy to know whether youre plugging in to an active outlet or not. My PC only as two USB 3.0 ports adding this baby give me LOTS more options. Phones charge faster. Portable WiFi Jet packs charge faster. Pictures transfer faster. Everything is faster with USB 3.0 and this gadget makes it nice and convenient. No reaching behind and around everything else. Just set the hub up somewhere convenient, plug it into a USB 3.0 port and now you have turned that one port into 16 ports.

I have a music production studio and have many USB devices that need to be hooked into the computer. I use hard drives, audio interfaces, synthesizers, midi controllers, etc. I figured I could use one hub instead of multiples to keep things clean. But nope, this unit can’t even handle 5 devices before connections start cutting out. Tried different plugs and different device orders, but sill issues. Returned it and picked up a Sabrent 10 port hub. Yes I wish I had a few more ports available for future expansion, but the most important thing is that everything works. And now it does. 10 devices and they’re all working. I don’t know, maybe this hub is designed for multiple thumb drives or charging multiple phones or something. But it just didn’t work for my needs. I would expect it to perform better due to its cost though. Especially since the Sabrent can handle10 of the same devices with no problems.

Absolute must if you’re like me always changing out usb peripherals between racing and flight sim gear.

Simply plugged in - with some other hubs I did not always get a good connection, but this has solid connections for each item plugged in.

This is a very functional powered USB hub that also has the ability to charge cell phones and other devices. I own this Hub and have it on 24/7. I have yet to notice any issues with the device getting hot - that’s a great sign that speaks to a well constructed hub. However, the only negative I have in regards to this hub is the price. I actually waited several months for the price to drop to purchase. Highly recommend if you don’t mind the high price point.

I picked this unit up a couple of day ago and couldnt be happier. First of all this is a well made, solid device. You know when you transfer files from one directory to another on your internal drive? It only takes seconds. I am getting a transfer rate of large files from my internal drive to my external drive at just about the same speed. Plus all the ports are charging ports too. Highly recommended.
