This is a module that enables Qi charging for Logitech gaming mice. Currently not sold in Japan. This is a Qi charging module that can be used with Logitech wireless mice. It is not a Logitech product. It allows the use of a regular Qi charger instead of a dedicated PowerPlay mat. It's very convenient because you can charge with a regular Qi charger. I bought it online, but I only took it out of the box and never used it. No significant price reduction.
