Perfect for a midi keyboard music setup
Style: 8-in-1
I bought this to setup a midi keyboard for the worship team. I connect a couple ipads and the keyboard and it works great. It powers all the devices, has good length for the power cord and just works as intended. What else is there to say. It's a good product.

Lots of ports, and lots of power!
Style: 8-in-1
I was in search of a hub that not only had a large number of USB A and USB C ports but also was externally powered, so that it can give some power to all the things plugged into and take a little load off of the laptop. It is working great and I would recommend.

Anker 8 in 1 USB Hub excellent choice!
Style: 8-in-1
I’m always expecting more for my laptop power supply than it can do. I bought this hub because I needed powered connections not only to reduce the strain on my power supply but also help them operate more effectively. The Anker USB hub 8 in 1 solved the dilemma, highly recommend.

It does exactly what's advertised, which is perform poorly
Style: 8-in-1
1 star because it does exactly what's advertised if you scrutinize the listing, but what it does is so mind numbingly stupid nobody would assume it's this poor of a product. It comes with a stand alone power input, but to use it properly you need an additional USBC power supply to feed into it, and oh yeah also most of the USBC ports deliver low power, and the USBA ports deliver no power. This is like a weird peripheral stuck in a time warp torn between 1998 and the modern day. Nobody is asking for this and the subtlety of how dumb this design is is reflected by the "Frequently returned item" disclaimer. Whoever product managed this needs to rethink their career

Worked fine.
Style: 8-in-1
When I tried to plug in our new backup hard drive, I got a message saying something like "USB power exceeded." Bought this, plugged it in, attached the hard drive, no problems since.
