Samsung’s previous Eco Remote featured the ability to charge through the sun, and this one does that as well. However, it also receives juice from the radio waves emitted by your router. Samsung describes what the remote does as “collecting routers’ radio waves and converting them to energy.”

You might be asking yourself why your phone can’t use this same technology to stay charged. Basically, the amount of energy generated is only sufficient for low-power devices such as a remote or something along those lines.

Of course, you can also charge the Samsung remote over USB-C, so if you’re not getting enough power from your router or your indoor and outdoor light, you can charge it up the traditional way. There are no AAA batteries in the remote, which is great because it cuts down on the amount of waste generated by television remotes.

The remote feels like something out of the future, and we’re very interested to see what Samsung can do with this technology going forward.
