How long is the cord?

The cord is 12 feet long. We also offer an extension cord. We have had some customers extend the cord over 50 feet

Why don't you give the Voltage and Amps? That's the one thing you want to know about when buying one of these.

It is a 20VAC 10VA Power Supply. Input is 110VAC 60Hz.

Will this help the voltage with my mechanical chime? My mechanical chime will only sometimes ring loudly.

It may. If you have a traditional transformer it may not be powered properly for the Nest Hello. However, you may also have a wiring issue. We are happy to discuss it with you and help you trouble shoot. service@ohmkat.com

I need the cable to be longer, I just purchased the adapter, but need the total length to be 9 meters. (27 feet), where can I buy it ?

I never bought same as this bell but I have another type and I bought longer wire for it from Amazon but you have to write for them same type as you need
