This improved 4-port USB hub can power devices that require it when connected (such as an external hard drive). If you're trying to increase the number of available USB ports you can use with your laptop or workstation, be aware that you'll lose a maximum of two (one for connecting to a hub and/or one for the power supply when not in use). do not plug in power). to the wall charger). It's also nice that you can secure the hub so it doesn't move when you have a handy bar to mount it on.
