Any suggestions? I'd prefer bluetooth so I don't have an adapter taking up a USB port when I don't need it.
Wait... You want a Bluetooth mouse so you don't have an adapter taking up a USB port, but you want it to charge via a USB port?
I use an Apple Magic Mouse with a mobee induction charger. Works well and is very convenient.

...and then you post a link to a device which... charges your Bluetooth mouse from a USB port!
Duh.
