24Volt 500mA UL Certified Doorbell Transformer, C Wire Adapter Thermostat, Competible with All Versions of Ring Doorbell and Thermostat for Nest Ecobee(16.4FT Charging Cable-UL Certified)

This product works great and is extremely easy to install. The cord length is perfect, the build quality is perfect and the power supply is perfect.

I bought this to use with my Ring doorbell on the back door. For some reason, this doorbell runs out of battery power very quickly, as much as three times quicker than the front door bell cam. Not sure why and have tried swapping different batteries and such, but that did not work. This power supply fixes the problem and the door bell cam is always charged.

Works great at being able to make my pellet stove connect to Wi-Fi so it can be remotely controlled. Works great if you want the heat off when your not home and are able to turn back on before you head home. Helps save big on pellet usage

Better to get battery doorbell with solar kit...but this works..just have to hide wires.

Works well with the ring doorbells

Very easy to install

it comes with different length wire as needed

It works great with my Ring doorbell. Length of the cord (16FT) is good enough for me to plug it in to the nearest electric outlet. Easy to install in the doorbell.
