Video Doorbell Pro Voltage Dropping?

@Marley_Ring

May I please ask you or someone review this info that I just realized? Despite you stating my power supply should be sufficient, could you revisit that assessment after reviewing the below information please? I’ve realized while my power supply should be sufficeint for V AC, it may NOT be sufficient regarding volt-amps/mA. My DB Pro continues to work fine, but the voltage continues to drop. I’m currently at 3916mV and I’m concerned it’s going to eventually die on me.

The power adapter I purchased that I mentioned above supplies 24V AC at 500mA. This equals out to 12 volt-amps.

The Ring Plug In Adapter supplies 24 V AC at 20 VA , which equals out to about 880mA.

Per the below page “Ring Pro requires a power source that supplies a minimum of 16 volts AC at ~20 volt-amps when connected directly to a transformer, plug-in adapter”

It looks like I’m 8 VA (or around 380mA) shy of the power that the Ring Plug in Adapter outputs., but I’m higher than the recommended 16 V AC as recommended above.

I’m unclear if my power supply is sufficient at this point based on this information. Could you please let me know if I need to purchase the Ring Plug in Adapter? 20ft isn’t long enough, but I’ll just need to figure out how to make it work.

Thank you again.
