Review on Dub-H4: D-Link 4-Port USB 2.0 Hub with Fast Charging Ports - Mini USB, 5V/2.5A Adapter by Arnold Carrigan

Just the right size for my desk. Not so small that you have to hold it carefully when connecting devices. Not so small that a mouse can drag it across the table. Just the right size. Small feet at the base keep it in place. If not, put a velcro on it and connect it to the velcro on the table. For most purposes (using a mouse, keyboard and reading a flash drive) there is no need to connect a power supply. I have the power adapter handy, but I don't plug it in all the time. I really appreciate the long cable length between the computer and the hub. I think it's 4 feet if I remember correctly.
