Maxdot Doorbell Transformer 24V 40VA Compatible with Ring Doorbell

I recently installed the Maxdot Doorbell Transformer 24V 40VA to power my Ring Wired Video Doorbell, and I couldn’t be more satisfied with my choice. This transformer is not only compatible but also provides a stable 24V output, ensuring that my doorbell functions flawlessly. The installation process was straightforward, thanks to the clear instructions included in the package. I appreciated that all the necessary components were provided, which made setup a breeze even for someone who isn’t particularly handy. Within minutes, I had it connected and ready to go. One of the standout features of this transformer is its UL certification, which gives me peace of mind knowing that it meets safety standards. It operates quietly and efficiently, with no overheating issues so far, which is a huge plus for a device like this. Additionally, the build quality feels robust, and the sleek design allows it to blend in seamlessly with my home’s electrical setup. It’s been working perfectly, providing a reliable power source for my doorbell without any interruptions. Overall, I highly recommend the Maxdot Doorbell Transformer for anyone looking for a dependable and easy-to-install solution for their wired doorbell. It’s an excellent investment that delivers on performance and safety!

Previous transformer was a 16v 10 VAC unit that came with my new home build. I had a Google Nest doorbell cam installed from day one and from the onset, it never quite worked 100% (i.e. - doorbell button had to be pushed and held for a good second or two to ring). Fast forward several years the Nest died and I replaced it with another brand. Right off the bat the unit was having issues working and would freeze up. After diagnosing and trying to eliminate the issues, I came across that the original home transformer may not be up to the task. Giving this unit a try so far has been positive as the doorbell has no issues and appears to be keeping the supplementary battery up to charge (one of the issues before).

I originally had the Nutone C905 Transformer paired with the BK125LWH-1 16VAC Chime. When I upgraded my standard doorbell to the Google Nest Doorbell (Wired, 2nd Gen), the existing chime stopped working correctly—it just made a humming noise. I discovered that the Nutone transformer only supplied 16V, while the Nest doorbell requires a transformer with a voltage between 16V and 24V. To resolve this issue, I replaced the old transformer with a new one. However, I also learned that the chime must be compatible. So, I purchased the Newhouse Hardware CHM24V 24-Volt Wired Doorbell Chime. Now, everything works perfectly—the doorbell rings clearly with both front and rear tones, and there are no issues at all. Helpful Tip: Before replacing the transformer, take a picture of the existing setup, especially the wiring. It makes the installation much easier. And always remember to turn off the power to the transformer, chime, and doorbell before starting any work.

Bought this 11/2021 to power a single Nest Hello doorbell. It worked OK (I say OK because it always had a slight hum from day 1) until it finally crapped out 7/2022. I originally bought this specific brand and model because of the good reviews and because I was considering powering an additional Nest Hello doorbell at the back door, but it doesn't seem like this one has what it takes to handle even 1 for the long haul. Edit: I contacted the seller and inquired about warranty service due to having issues 7 months after purchase and they offered to send me a new one with no questions asked. Good customer service is worth a lot in my book because even the best products will fail from time to time, so I've upgraded my rating to 4 stars. I'll monitor the new one for a period of time and if it doesn't have a hum and continues putting out consistent VAC, I'll consider upgrading my rating to 5 stars because 1 faulty unit shouldn't represent the product as a whole when the seller jumps at the opportunity to make it right.

Used for our Ring doorbell, now we can spy on people outside lol

Works great. If you have anything working as a doorbell that has a camera or other modern power hungry features,, you'll want to upgrade to this in your house. The vast majority of homes have a far less powerful one that will not supply enough voltage for modern doorbell cameras, etc to work optimally. Standard transformers are around 10-14 volts or less for a basic old school doorbell. Modern camera doorbells need a minimum of 16V, and most manufacturers recommend 24V.

The screw/blade terminals on this unit are defective in design, not just manufacturing. Most of this you can see in the product photo itself: 1) Look at the product photo. Notice the screw heads on the terminals are too small to properly hold down even spade connectors that well, much less bare wire. What you can’t see is that the gauge of the screw shaft is also very thick so there’s not much space under that screw head. 2) Notice the blade terminals are perfectly smooth. They’re not supposed to be super smooth, they’re supposed to have some ridges or dimples to help them hold a blade connector. 3) you can’t tell from the photo, but the tolerances on the threaded screw terminal holes are very poor. The screws were already loose when I got the thing and then I found that one screw couldn’t be tightened at all, it would just turn and turn as though it were stripped. But I suspect the holes were just very poorly tapped because the item did not look used. This is just another one of these third-world products where a critical but cheapest and easiest to get right part is cheaped-out on in an effort to save 1¢, ruining the whole thing. In this case, lots of expensive copper and manufacturing effort has gone to waste because someone couldn’t be bothered to do a proper job with the least expensive critical path component of the whole thing. This is a really stupid way to save money because you lose $10 trying to save 1¢. The design and manufacturing decisions for this product are bad and the VAR did not properly evaluate the white label product they are branding before making a deal with the manufacturer.

Works really well with a eufy doorbell. Very heavy. Use with a metal plate or box. Being UL listed sold me on it versus a lot of cheaper options.

The 16v 30va transformer didn't have enough power for two doorbell video cam. It's good enough for one video doorbell cam but not two. The video was freezing or losing connection or not connected at all. It wasn't a streaming problem because the internet is on a 5G network. I called up Ring and they suggested to boost the power by switching to 24v 40va. I ordered a more powerful Maxdot 24v 40va transformer and installed it. It worked flawlessly and problem solved.

Funciona bien, aunque tengo muy poco tiempo con el como para valorar la duración, pero por ahora esta funcionando perfectamente

Had to upgrade my previous transformer to this since it was dropping connecting to the ring door bell.. Once done Never has the power dropped .. Easy to install ... I had tried everything before this to try and keep my video door bell hooked on to power supply but nothing worked .. Problem was solved once we upgraded to this .. Definitely Recommend ..

Sirve para Doorbell2 revisen las dimensiones, es pesado y grande

Got this to replace a 10V transformer so that a Ring Pro Video Doorbell could be installed. If you are comfortable doing basic electrical work, it is fairly easy to install. Just make sure to turn the power off to the doorbell circuit beforehand. The unit was heavier than expected so need to make sure it is supported well. The doorbell has been working great so far with no issues.
