Wirelessly charge your mouse while at play or at rest with the Logitech POWERPLAY Wireless Charging System. With Logitech POWERPLAY, you don't have to worry about charging your wireless Logitech gaming mouse at a dock anymore. Logitech POWERPLAY creates an energy field above the surface of the mouse pad, thanks to the innovative application of electromagnetic resonance. The POWERCORE module attaches magnetically to your compatible Logitech gaming mouse and turns the POWERPLAY energy field into a charging current. With LIGHTSPEED technology, your gaming mouse can pair directly to the POWERPLAY base, which eliminates the need for an additional USB data receiver.
