what to buy??

I want to buy one of these but don’t know what I need??? 2.0 or 3.0 -powered or non----on and off switchable??

Hi Stan-

Can you share some details about your computer (windows/mac/linux?) and whether it has USB 2 or USB 3? If you’re unsure please provide the model number for your PC (Mid 2012 MacBook Air, Dell Inspiron 1720, etc) and I can figure that out.

I assume you’re shopping for a USB hub rather than one of our other products based on the powered/non powered question? Non-powered hubs are ok for splitting one port into two for adding a couple of low power devices like mouse and keyboard, however they won’t work if you’re using higher demand devices like USB graphics adapters or external hard drives.

Sorry, but I’ll need more details about what you’re trying to accomplish to be able to be helpful. Please let me know a little more about your system and goals and I’ll be more than happy to help.

Best wishes-
