New Samsung remote controls charge with router radiation

In the environment of the large technology fair “Consumers Electronics Show”, short CES, Samsung now presents a novelty, which should not fit battery manufacturers at all.

CES in Las Vegas also has to contend with restrictions in 2022 as a result of the Corona pandemic. This year, prominent companies like Microsoft, Amazon and Google have already cancelled their participation and the organizer has shortened CES 2022 by one day. Nevertheless, we can expect some announcements and new products. Even before the official start on January 5, Samsung presents the first novelty – the new “Eco Remote”.

Samsung remote control “Eco Remote” with new charging technology

Samsung makes the next step to get rid of AAA batteries for its own remote controls. Many TVs from 2021 already came with battery-free remote controls, the solar-powered “Eco Remote”. Samsung calculated it could save 99 million small AAA batteries in seven years with the product. But the South Korean company has now come up with another charging method for 2022. This will be integrated into the remote controls in addition to charging with sunlight.

11 batteries in test – cheap often better than branded products

We’re talking about the possibility of charging the “Eco Remote” with radiation from the WLAN router. Compared to solar technology, that sounds pretty cool. Power harvesting, or RF harvesting, is the process of collecting radio waves that the router emits during operation and converting them into energy. Besides wireless charging with light or via radio waves, the new Samsung remote can also be charged via USB-C using a cable.

Will we also charge smartphones via radio waves in the future?

The technology sounds amazingly plausible. So will it be used for more wireless devices in the future? Will you just have to put your smartphone in a room with WLAN coverage and it will charge? These hopes must be disappointed for the time being. This is because the technology is currently only suitable for devices with low energy consumption. This generally includes neither smartphones nor other devices with large displays. Similar to charging with light, the technology will therefore probably only rarely be used. The charging results are simply still too manageable.
