In Tokyo, there is a kind of inn that provides a rest for office workers who work overtime until they cannot take a bus home, and they provide a comfortable bathing and resting environment in the city where the land is small. Just as we can only rest while we sleep, we want to provide users and devices with a charging device that is small and fits perfectly into the space. A bedside lamp capable of charging three devices at the same time can solve the problem for the user.
