One of the most impressive, brilliant pieces of smart home technology is truly minimalist and essentially invisible. Any parent who has dealt with the whining (or occasional meltdown) when all the batteries for the Wii remotes are dead will instantly see the beauty of this innovation. The Ossia Cota Forever Battery is a standard size AA battery which functions with wireless charging. This means if you put the charging unit within a couple of meters of the where the remotes are stored, they will charge wirelessly. No plugs, wires or charging pads or finding that one little screwdriver to get the battery door off. Not only will the battery issue go away, but it’s a powerful motivator for kids to PUT THEIR STUFF AWAY!
