24V 40VA Thermostat and Doorbell Transformer, All Versions of Ring Doorbell

I purchased the EPLZON 24V 40VA Transformer primarily for a non-doorbell application: powering my whole-house humidifier. Even though it's marketed heavily toward Ring and thermostat systems, it performed flawlessly for my HVAC accessory needs. The installation was straightforward, and the unit immediately supplied the necessary 24V power. It has been running continuously for weeks, maintaining a steady output with absolutely no operational issues or excessive heat. This 40VA rating provides plenty of headroom for various low-voltage devices. If you need a dependable, high-quality replacement or new installation transformer for any compatible 24V system—whether it’s a smart doorbell, thermostat, or a humidifier like mine—this EPLZON model delivers reliable, consistent performance. Highly recommended for its versatility and flawless function!

Works perfect

Excellent product, used it to replace old doorbell transformer for a smart doorbell.

I returned it as I did not need it. Doorbell chime did not feed off of doorbell. Both are wireless.

Needed to mount a Ring camera doorbell on the outside gate of our house. This transformers was perfect for power devices like these which would ordinarily run off of the power from a door bell circuit.

Works great with my Lorex video doorbell.

Died within a couple hours and when I first hooked it up, was already below voltage...21v. Looking through all these transformers, a lot of people have been returning them. I'm going to see if ring has an official one because these seem to be garbage.

Purchased this to increase power to my Ring doorbell Pro. Even though my house is only two years old the16V transformer was inadequate. In the Ring app, it said my power output was level 2. Just enough to keep it powered, but not adequate to make my doorbell chime work when the button was pushed. I also know that the old transformer was very hot when I took it off meaning it was being overworked. Now since I installed this new one, I’m at level one power output, and my doorbell chime works loud and clear. Actually better than it did before. The only negative thing I have to say about this product, the mount on the transformer was bent pretty badly. But I used the wiring port to screw it to a face plate instead so I didn’t need the four screw mount. Great product, easy to install size is typical for a transformer like this. Definitely Ring compatible and I recommend it..

Encontré difícil dar con un proveedor en quien confiar, al menos este aparato llegó funcionando, había comprado otros pero no funcionaron.
