So, the Corsair one using Qi charging tech. This one does not.
There are benefits to each - Corsairs will work (theoretically) with and Qi device, like your phone. But, there's a sweet spot that charges your devices...the rest of the mat is just a mat.
This one will not charge your phone or any device not specifically meant for it - but the ENTIRE pad is a charging surface for the mouse. Also, the pad syncs with your mouse, so you can remove the dongle/adaptor that connects the mouse to the computer.
