It’s also far lower power consumption than something like a laptop, and so doesn’t suffer as much for the inefficiencies inherent to wireless charging. Laptops have attempted various versions of inductive charging in the past (to varying degrees of success), and phones now do “Qi” charging, but a mouse is one of the most sensible applications. Magnetic resonance and inductive charging have been around since Nikola Tesla was alive, so it’s not new technology – but hasn’t been deployed in a mainstream peripheral implementation. Before PAX Prime, we took apart the Logitech G903 mouse and wireless charging station, known as “Powerplay.” The G903 mouse can socket a “Powerplay module” into the weight slot, acting as one of two coils to engage the magnetic resonance charging built into the underlying powerplay mat.
