My new Ring doorbell required 16-24 volts (our older Ring doorbell only required 10v) so went with this transformer thinking it looks a little heavier duty than others on Amazon, and least it has a brand name I have heard of, but I know that is not necessarily meaningful. So far so good on it working, I did test the output voltage out with my multimeter and it showed 19v from the unit. In the Ring app it shows the doorbell receiving 17 to 18 volts. I also left the wiring hooked up to my 45 year old vintage Nutone door chime and so far the extra 7 or so volts supplied with this transformer has not affected its operation, still chimes as usual. I kind of doubt these old chimes are too picky on voltage.

Arlo wired doorbell was acting up, only working on and off, and not ringing the mechanical bell as advertised. It felt power related, but I had a hard time finding issues- eventually I found out that the doorbell was wired at 16v as it should be, but that it dropped to 14 across the Arlo terminals.I had to search for the doorbell transformer, but once I found it, I saw that it was only rated for 10VA I bought this one as a replacement and it showed up next day as promised.The installation only took 5 minutes or so and the Arlo has been solid ever since. The doorbell works again and is twice as loud as it was before.

Replaced my transformer due to a Ring doorbell that kept shutting itself off.

TLDR;Good quality transformer for wired doorbell camera and address light.Slightly largerMuch better heat management. Barely warm compared to the too hot to touch cheaper one I got prior to this upgrade.Has a safety feature that shuts off if there is a fire hazard. Spend the money on this for peace of mind.Details:Unit itself is quality. It is made in china to Broan Nutone specs which is a US company. You would be hard pressed to find anything made in the US nowThis works with blink doorbell camera and to power my address light. Has sufficient juice and does not overheat. My old one which came with a house built in 2000 was a 16v 10va. It could not provide sufficient power to support a ring, blink, nest, arlo, eufy, Wyze doorbell camera.Bought a cheap unknown brand replacement with 16v 30va specifications but it got too hot to the touch. Normal to be hot. Some say 100 degrees is normal. Some say up to 120 degrees is normal operating temp. I can tell you it got way too hot and I was not comfortable sticking with it.Winded up paying double the price for this Broan Nutone unit and it is a significant improvement. No longer hot. Barely even warm. Size is bigger and I imagine it’s a better heat sink. So I guess size does matter.Minor notesBox came damaged and fins bent. Didn’t have to use them but bent them back using pliers for aesthetics.

Update: Three years after purchasing the second doorbell transformer (so yay, it lasted longer than the first time at least), my ring suddenly died. I thought it was the Ring's fault. It was old. Time for a new one. I got the top of the line Ring Pro, and 2.5 months later? What should happen? Same exact thing - doorbell completely stops working. Zero response. Ring is sending me another, but the tech noted that the same exact thing had happened to two Rings, which would indicate a very likely transformer problem - that it's erroring out and occasionally sending bigger jolts of power than it should. So after killing two rings, this thing is officially going in the trash and I'll be getting another brand.I got this doorbell transformer initially a year and a half ago. Needed something with enough power to power a RIng Pro Doorbell. This did great. For a year and a half. Out of the blue, it fried. Not working at all. So I had to rebuy. Maybe I should have gotten a different one, as 1.5 years seems really short for a doorbell transformer. But I'm hoping this one will last longer than the first.

I bought this so that I could install a Ring Video Doorbell Pro on both the front and rear doors of our home. I have had no problem at all with it providing power to both. I'm not using the mechanical chime originally installed in the home so I can't speak to whether the transformer output is enough to also supply this, but I get the impression that Ring has compensated for this in the power modules included with each doorbell.

I have three chimes in my home and when they installed it they had only used the original 10 A transformer and the chimes had never worked correctly. Replacing the transformed completely solved all the problems.

This is a good transformer. It comes in a brown NuTone box and has a one year warranty.There is a small instruction guide for installations (1 bell, 2 bells, etc.).The transformer wires are in a threaded cylinder shaftess than 1” long. You insert this into a punch out on your juction box so you have no exposed wires. You then connect the common, load and ground (white, black, and green) to the corresponding wires in your junction box.If you are replacing a transformer you may first need to find the transformer unless it is by your panel. They tend to be in a straight lime from your doorbell (straigh line, shortest distance between points and all), so look in the attic, crawlspace, or basement in a straight line into the house from the doorbell, and near another power source like an outlet. Mine is in my crawlspace.You may find, as I did, that my ancient transformer was over-tightened onto the junction box. I ended up pulling off the box (POWER OFF! Or at least wires capped of you are a pro). This allowed me to turn the transformer unit and easily unscrew it.My only installation issue: this unit was slightly deeper than my junction box, and once I inserted it into the punch out hole it rested on the joist before the junction box. I just added some wood behind the junction box so both transformer and box are secure/nailed in to the joist.Installation itself is like 5-10 minutes. I spent more time finding my transformer and fussing with the old one’s “frozen” mount than I did the install.This one works great. Its 16v-30a. If you have a Ring Pro, you need this. Don’t get a 16v-10a or anything less than 16v-30a.If you have a long run to the doorbell (more than 60 feet from the transformer) use a 24v-40a with a Ring.I tried to get away with my old transformer for my Ring Pro and I did for a while then it died. Even before it died sometimes it would not fully ring my mechanical chime or drop WiFi connection with a low voltage message.

The output power under load, i.e. ringing, drops so that the system crashes and need to reboot after every ring. This is a wired system with a mechanical chime. The transformer is being returned.
