The Aukey 10-Port USB 3.0 Hub is a USB 3.0 hub that is made up of aluminum to match the design of your Mac. It measures 183mm x 66mm x 34mm and weighs 180g. Because it is USB 3.0, it supports data transfer rate of up to 5Gbps. It comes with a 12V/3A power adapter and a 1m USB 3.0 cable (Standard-A to Standard-A).
Personally, I think 3A may be too little to a 10-Port USB 3.0 Hub. From the USB 3.0 specifications, 900mA is the maximum amount of current that can be output from a USB 3.0 port. When a device is attached to a USB 3.0 port, a device will reserve about 500-600mA for data transfer (even when not in use) and leave the rest for charging (300-400mA). So don’t expect to use this hub as a charger. Maybe that is why my current Anker USB 3.0 9-Port USB 3.0 Hub has an additional 10th port that does only charging at 2.1A.
