Transformar rating

Should a 12v 500mA (I guess that is 6VA, right ? ) transformer work with the básic Ring doorbell? Is it enough power?

What resistor rating should I use? The same 25ohm 50 watts?


Good question @nospamprl! As you know, our Video Doorbell operates of the battery primarily. You can certainly wire it for an additional charge and operation of your chime kit. This installation will require an 8 - 16 VAC transformer. Check out our help center article about wiring your Video Doorbell for more information on the resistor. I hope this helps! :slight_smile:
