Hi Can I use this transformer to power my ring 3
Hi @Twizz1. You can find the chime kit compatibility list for the Video Doorbell 3 in our Help Center Article here. You’ll want to make sure the chime kit is compatible and that the transformer is 8-24 VAC, 40VA max, 50/60Hz. You can find this information on the product page for the Doorbell 3 as well. I hope this information helps!
