Review on Portable 4-Port USB 3.0 Hub with Power Switches and Lights - High-Speed Data Splitter and Extension Hub for Laptops, PCs, and More (No Power Adapter) by Matthew Shankar

This USB hub has 4 ports. My 10 year old son has been asking for a USB hub for a long time and is very happy with this hub. He does a lot of animation and always has a tablet, charging pen, bluetooth adapter for speakers and too many other things on his work station. He has a hard time charging all of these things with just two USB ports on a PC. Now he can connect multiple USB devices to one PC with this amazing little invention. The on/off switch is an added bonus. I wish the cable was a bit longer. The device is so small that it easily fits in a laptop bag when traveling and can charge multiple USB devices at the same time. Overall a great product.
