24V 40VA Doorbell Transformer - Heavy-Duty Copper Core for Ring Pro/2 & Nest Hello, Easy Install Hardwired Power Supply, Thermostat/Chime Compatible

I bought this VIIVria transformer after my Ring Video Doorbell kept showing low power errors and randomly disconnecting. Swapping out my old transformer with this one completely fixed the problem.I’m not an electrician by any means, but installation was pretty straightforward. Once it was wired in, my Ring booted up right away and has been working perfectly ever since—no more warnings, no lag, no issues.It provides plenty of power (24V, 40VA), and it's been totally stable. No buzzing, no overheating—just solid, reliable performance. The build quality seems good too. It feels like something that’s going to last.If your smart doorbell isn’t getting enough juice, this is honestly an easy and affordable fix. I’m really glad I went with this one.

Replaced a 5V transformer to allow the Eufy wired doorbell to work. Easy install and works well.

Works well so far. No problem installing but use electrician if not familiar with wiring principles. Works with my 40 year-old door doorbell chime. Specs indicate support for Ring and Google video door bells and chime specs per the research I did.

The transformer worked great until it didnt. It died after four months of use. Would not recommend.

I installed this so I didn't have to charge my nest battery door bell. It was easy to install. time will tell how long it will last.

Functionality:Easy installation and great for Ring doorbells.

Description of this item correct. Easy to wire. Arrived on schedule. It's working fine.

This was a replacement for my multi-zone boiler. It came with everything needed for a professional install. The transformer can be mounted in a steel box with a 1/2 knockout hole or it has the option to mount it with the included 4 bolt pad. I chose a metal box with a cover that had a 1/2 knockout and simply installed the transformer to the plate and tightened with included nut which made for a great tool free install. They really should provide a pic of the optional mount on back side. Wiring is of decent quality a gauge and should provide many years of service. My system uses zone motors to control heat and it handles the load with ease. If you are looking to use this for doorbell solution it would handle the task easily. his was less than half the cost of the same rated unit at the big box stores and greater mounting options. With Amazons fast shipping I never left the house and saved time and fuel running to the stores. Would definitely recommend this transformer for any needs requiring the rated specs.
