Say hello to the Roll Instant Rechargeable Mouse. This slim guy can be charged by the laptop that you are working with and even when it’s being used. The charging is done via short-distance wireless charging as it uses wireless Bluetooth technology through resonant inductive coupling (electromagnetic induction) for wirelesses charging. That’s a lot of high-tech words for my simple mind; nevertheless you get the gist. This technology enables a slimmer mouse volume as there is no need for a large battery.
