This 3-port network adapter comes with an AC power adapter. I was able to use the Ethernet and the USB slots (with memory sticks as well as charging a phone) without the power adapter. The power adapter can be used for USB devices that require more power than you can get directly from the USB port.
This network adapter is 4.125"L x 1.75"W x 0.875"H. It weighs 2.3 oz. The network cable is 2.5" long. The power adapter has a 68" power cord.
To see whether it performs up to its specification I tested it connecting two Linux systems using iperf peformance measuring tool. I also compared its performance with two NICs built-in into my computer.
The network adapter performed well, with the speed one might expect from a good quality Gigabit adapter.
