Ring 4 Transformer UK

Hi. I have the Ring 4 device, it is hard wired into the house mechanical doorbell which runs off the mains. However the Ring 4 battery will not charge. Do I need to buy a transformer? If so then which type. I am in the U.K.

Thanks.

Hi @user620. If your Ring Video Doorbell 4 is hardwired to your mains, it should be receiving a trickle charge. This Help Center article here has more information on how this process works.
