I have owned the Ring Pro doorbell for about three years, but I never realized that it was not working correctly. I installed the Ring Pro doorbell per the instructions, installed the Pro Power Kit on the internal doorbell, and verified that my existing doorbell had a 16V transformer. Recently I was experiencing the doorbell hanging at times and going offline periodically. I went online to Ring.com and read many reviews about the need for a 24V transformer in order to power the Ring Pro as well as your internal (existing) doorbell. I opted to replace the 16V transformer with this 24V transformer mainly because it was old and probably not providing the needed power. It was an easy replacement and upon testing discovered that my internal now plays the Ring sound as well as its original ding-dong sound. Long story short: Most new 16V transformers (let alone old ones) cannot provide the power for the Ring Pro AND the existing doorbell. I hope this helps because the frustration of the Ring Pro going offline causes anxiety when you are trying to answer the doorbell remotely from your phone. When you get the "Cannot connect to your wifi" error message when trying open the Ring app, you do not know if the issue if your router or the doorbell. I have not experienced that error since I installed this transformer.

I read a few reviews etc and I had a problem with my Ring Pro not being able to get enough juice.

I contacted Ring service but they sent me a pro kit that did not work; Ive already using the same kit :/

Since they werent sure what the error was; they thought it was my WIFI which Ive checked and it was not. So after some digging, Ive found out its the power that was causing the problem. I guess each time someone ring the doorbell they juice drops because it also powers my regular doorbell chime which sucks up the juice.

After installing this badboy here; the problem is solved.
BOOM done.

I recently installed a Ring pro doorbell and watched a couple install videos on youtube before attempting and upgrading the transformer was the critical piece I needed before I started.

Install was straight forward. Find breaker that controls power to the tranformer, connect white to white, black to black, ground to ground and the two wires to the doorbell to the top screws of the unit.

The Ring itself reported insufficient voltage for a while after setting everything up but after a while it showed normal voltage and has been showing such ever since. Not sure what was adjusting but everything works and this transformer has enough voltage to upgrade my thermostat as well if I want to.

Was able to make my ecobee4 themorstat work. My old furnace only had 2 wires to thermostat I belive W and Rc with jumper to Rh. I bought an aditional thermostat wire . So the old thermostat wire connected to W and Rh and the wires from the transformer C and Rc. The transformers has marking to know which is the C wire. Must turn off power/breaker to the line before installing. I always check with the voltemeter after power down breaker to make sure there is no electricity. If you do not know how to do it get a proffesional.

This worked great with SimpliSafe doorbell cam. I have the old style mechanical doorbell that goes "ding-dong" and I had no trouble after I replaced the under powered 12V transformer that was keeping mine from working.
I did not need to do a resistor nor the "fix" SimpliSafe provides for doorbell problems.

I believe the problem others are having is with the new electronic door bells that use much lower voltage and mistake the low voltage draw the doorbell cameras use to operate as a trigger to ring nonstop.

The fix, in my opinion, is to put a resistor or small relay at the bell "hot" wire and not at the transformer. So it only lets current flow to the bell when the full 24v is activated when someone pushes the actual doorbell button.

Bought to use with eufy doorbell cam which requries 16-24VAC. The existing transformer in my house was from 1970 and only provided 8VAC. It was located in the basement near the breaker box, along the joint between ceiling and wall. If you buy a doorbell cam such as ring, eufy, nest hello, etc - make sure your transformer can provide at least 16VAC in order for the doorbell to work properly. The presentation was a bit lacking, it was thrown into a cardboard box with no wrapping but other than that I have no complaints.

Cheap and quality product. Used it to install with a relay to control my millivolt heating system. Once installed on a junction box, I ran a red wire from one terminal to the Rh port on the Nest then the white wire from the Nest to the control side of the relay then back to the other terminal on the transformer.

My red and white boiler wires are connected to the opposite end of the relay and are controlled whenever the Nest completes the 24v circuit. Works nicely without the potential of the 24v and millivolt circuits coming in contact with each other all while keeping the Nest charged.
