I have seen a few other threads asking something similar, with conflicting answers throughout. I just installed a new Video Doorbell 3+, using battery power only. My house does not have any existing doorbell wires, mechanical or digital chimes, or transformers. I would like to potentailly use the PLUG-IN ADAPTER to provide a trickle charge. Would I need to use the wire-wound resistor with the official Ring PLUG-IN ADAPTOR (the one for the Doorbell Pro: https://shop.ring.com/collections/accessories/products/plug-in-adapter)? I realize some third-party plug-in adapters on Amazon (the ones with an output of 500mA) may work without a resistor, given the much lower power output.
This post seems to suggest that a resistor IS required. Quote: “The Ring Plug In Adapter can certainly be used with our Battery powered Doorbells. Keep in mind, any power supply that does not include an existing chime kit wired in circuit, will require a resistor.” https://community.ring.com/t5/Video-Doorbells/Can-you-use-the-Ring-Plug-In-Adapter-for-Ring-Video-Doorbell-Pro/m-p/26549
However, this post says to remove resistors when upgrading to the VD3 as "resistors are not needed when hardwiring a Ring Video Doorbell 3": https://support.ring.com/hc/en-us/articles/360041394411-Important-Information-on-Upgrading-From-Ring-Video-Doorbell-2-to-Ring-Video-Doorbell-3-
So which is it? Thanks for your help!
