This Item: 3 Port USB 3.0 Hub with Gigabit Ethernet Adapter NIC, Portable


Total Price: 3 Port USB 3.0 Hub with Gigabit Ethernet Adapter NIC, Portable is rated 4.60 out of 5 by 5.
Rated 5 out of 5 by from Nice product except for the cumbersome external power supply I bought this to connect to my Surface Book when travelling. It is a nice product that works as advertised, but I was quite disappointed to learn that is requires the use of an external power supply. That makes it very cumbersome to use in certain situations. I might as well be travelling with a full docking station. I looked carefully at the description, and there is no mention of the external power adapter.

Rated 5 out of 5 by from Perfect for our Surface Pro With the limited number of USB ports on the surface pro(1), we needed a USB hub for console cord and ethernet adapters. With this, we dont have to have two additional dongles plugged in and the ethernet port works out of the box without the headache of looking for the driver. Also has the usual Startech quality.

Rated 5 out of 5 by from Great Piece of Suppor Hardware This hub has been extremely useful for me to work on tablets without having to purchase a very expensive premium base. Attached USB and ethernet connections work in BIOS as well as Windows environments. Driver installation is automatic in Windows. The only downside is that power does not go upstream: the 3 attached USB devices are powered, but the device it is connect to (in my case a tablet), is not charged. Expected, but would be a nice feature. I've had very good overall experiences with StarTech products, and this is no exception.
