This is a module that enables Qi charging for Logitech gaming mice. Currently not sold in Japan. It allows the use of a standard Qi charger instead of a dedicated PowerPlay mat. It's very convenient to be able to charge with a regular Qi charger. Also, charging stops around 80%, which is gentle on the battery. Ships next day. Thank you.
