Q: is the resistor included?

The adapter does not come with a resistor. The resistor should be included with the Ring Doorbell.

Q: Can I wire this to power my doorbell while leaving the existing wires connected for the chime? Or is that a bad idea?

I wouldn't do it. You should have a transformer already wired to the door bell. Use the existing transformer or replace it for a newer and more powerful transformer. This power supply is used to power a ring battery operated doorbell to make it a wired doorbell

Q: The battery needs to be full for Live View. Why doesn't this charge the battery?

Dear Customer, Thank you for your question. This power adapter is an adapter, not a charger. It is hard-wired to power the doorbell, so it needs to be connected all the time. If there is no power, it will stop working. In addition, according to the ring official description, Compatible with Ring Video Doorbell 2 needs to be paired with an external resistor, Because Ring Video Doorbell 2 requires a resistor instead of a mechanical or electronic doorbell kit, this alternate configuration can run successfully,External resistor specifications are: 25 Ohms ± 5% 50W Wirewound Chassis Mount Resistor. I hope this helps you.

Q: Will these work with simplisafe's video doorbells?

Our power adapter is AC18V500mA, The doorbell needs to support 18V AC power supply, Can be used together
