This swing set generator allows public transport users at a station in the Netherlands to charge their phones whilst swinging back and forth.
Footage captured on June 21 at Utrecht Central Station shows people using the swings to charge their devices.
"At Utrecht Central Station you can find these swings that help you to charge your devices by playing, it is also a way to break your routine, to make a stop in your journey and just enjoy the moment by playing for some minutes," writes the filmer.
