Newhouse Hardware 16V 30VA Door Bell Transformer Compatible with Ring Video Doorbell Pro 30TR, for Wired Chimes

I bought this after I installed a ring doorbell to increase the charging capacity. I have had it for about 6 months and it has performed well. Was very crowded easy to install.

This review is for "Newhouse Hardware 24V 40VA Door Bell Transformer Compatible with Ring Video Doorbell Pro 40TR, Wired Chimes". We've had this installed for a couple of months now. It's been working great with our eufy E340 doorbell. It keeps the doorbell battery charged at all times. eufy recommends power supplies with minimum 16-24VAC and 30VA. Used a volt meter to check and this one certainly meets these specs.

“I just love having a doorbell!” — said no dog owner ever. After enjoying six months of peace and quiet (our old transformer died), we’re officially back to reality. On the bright side, this transformer worked perfectly and brought our doorbell back to life with no issues. Installation was straightforward, and it’s been working reliably so far. If you’re replacing a dead transformer, this did exactly what it was supposed to do. My dogs may not approve, but I do.

Works well for powering a Google Nest Doorbell Camera. The old transformer was only putting out 15.5v. I decided to go 24v and this for the bill nicely.

This Newhouse 24V 40VA doorbell transformer is an absolute powerhouse. I recently decided to try the Ring Wired Pro 3 doorbells, and knew that my existing transformer wasn't going to be able to come close. I had ordered another one from Amazon first, and promptly returned it when I saw zero UL or ETL markings on it. This Newhouse transformer was my next try, and I'm glad I chose them. Affordable, powerful, and easy to install. It fit in the exact same location attached to my main panel box as my old transformer, had easy pigtail wiring to work with which was robust, and the device is powerful enough to run both 4k Ring Pro 3 4k doorbells and both their dependent chimes without any sign of struggle. Exactly what a foundational electric component for your house should be - built solidly and UL certified, quiet, fits right where it belongs, and delivers on what you bought it for. If you are planning to go with multiple Ring wired doorbells, and you have existing wiring and a transformer that isn't up to snuff, this is a great buy. No need to get Ring's power injector - because this will do everything you need in the same simple seamless way that Ring and your home's existing wiring were designed to interoperate.

First off, transformer worked out of the box after I installed it. I purchased this in April 2020. It's still working after a more than a week. (I was afraid that it would have issues reading other reviews, but this transformer seems to be performing perfectly. I will update this review if it breaks down, but if I don't, that means it's still running) Backstory: I was excited to install my Nest Hello doorbell camera. I even checked before I bought it, that my transformer was sufficient to power it. After I installed it, the doorbell worked! But something was wrong, I realized my Nutone mechanical chime wasn't working. Are the wires in the way of the mechanism? No. After research, I found out that my existing 16v 10a transformer was not enough to power my mechanical doorbell. Unofficial "fixes" included taking off the limiter (not recommended) or getting a 24V transformer. After searching for solutions, the consensus that the safest solution was to get a transformer with a higher VA rating. I originally wanted to purchase the Nutone 16v 30va transformer but it would take longer and shipping wasn't free (also a lot of the pictures showed dented transformers) so I bought this. Review: Cosmetically, it looked just like my old transformer just bigger. Wires were slightly thinner but still pretty solid. I've read about transformers getting too hot while in operation. This got warm but nothing out of the norm. I know looks isn't everything, but it is a factor for me. Functionality. It gets the job done. After installing it, time for the moment of truth. Pressed the doorbell and now it's a LOUD Ding! AND Dong! I've heard some solutions only get a Ding without the Dong. Before getting this I wasn't sure if installing the transformer is worth the hassle. I thought maybe I don't need the mechanical doorbell. After installing it, I'm glad I did. 1. Mechanical doorbells are a nice physical real sound and not simulated electronic sound. Just sounds classy. It is distinguishable from other noises or sounds in the house. 2. No delay. Once pressed the door bell rings and everyone in the house can hear it. 3. The reason why the mechanical doorbell didn't work before is because there was a voltage drop, when the doorbell was pressed. I figured that can't be good for the doorbell camera in the long term. With a new transformer, I can have a peace of mind knowing there is proper voltage going to the doorbell camera. If you have a 16v 10va transformer, I highly recommend upgrading it to a 16v 30va transformer like this.

stays warm but not hot, fair price, very quiet, and had for over a year

The transformer works as expected however did not fix the mechanical door chime issue that I am having. May be a totally different issue at this point.
