REDLED RP-Karlton Onar Sign Wireless Plug-In Doorbell – Kinetic Button (No Batteries), 32 Melodies, 150 m

The REDLED RP-Karlton "Onar Sign" is a wireless plug-in doorbell whose push-button needs no batteries at all — it is kinetic, harvesting the energy of your press to send the signal. Plug the chime into any socket, stick the button by the door, and you have a working doorbell in minutes with no wiring and no battery to ever replace on the button.

The button carries a name-inscription window, the chime offers 32 selectable melodies with adjustable volume, and the wireless link reaches up to 150 m in the open. A learning system pairs extra buttons automatically, so one chime can cover a front and back door — or serve as a simple, reliable call button for an elderly or less-mobile person in another room.
