Upgrade for Nest doorbell.
My old transformer was too weak to run Nest doorbell. This does the trick! Easy install. Just hook up wires the same way as existing transformer. Thats it. Boom – Nest doorbell works perfectly.

Worked Great with Ring Doorbell
The first transformer I bought didn’t work with my Ring 2 Doorbell (I hardwired the doorbell) but this one worked out of the box and fixed my issues!

Exactly What We Needed
This item was used to provide power to our Ring Gen 2 Camera Doorbell. With the additional resistor, worked great. No more having to charge the Ring once a week.

30VA makes a difference
This larger power, 30VA, was required to make our Ecobee doorbell work. We tried both Arlo and Ecobee using our existing 10VA transformer and neither would charge. Both vendor specs say 10VA is sufficient. When 10VA didnât work for Arlo, we tried Ecobee. Still did not work. I triple, quadruple checked all wiring and measurements were good. Got lucky and noticed Ecobee spec on Amazon says 16VA is needed. Checked vendor site and it said 10VA. Tried this 30VA and everything works great, chimer and camera doorbell.

Use to better power house chime and a Ring Door Bell Pro
When I installed the RIng DoorBell Pro at my daughter’s house I also replaced the house door mechanical chime with one (another mechanical one) on the Ring Compatibility list (many of which have different brand names but are made by Heath-Zenith and are low cost). The chime only cost me like $20 at Lowes. The old chime, even before the Ring Doorbell Pro barely rang. The old transformer was 16v 15 amp. The new chime rang fine and the Health of the Doorbell was fine. However I wanted a better transformer to avoid issues. This new one is 16V 30 amp. I bought another one for my house to replace a little 10 A one. The old one used the metal box as the ground, this new one has a plastic nut to attach it and a separate ground wire. So I used a short green grounding wire from Home Depot (Lowes sells ones that have a poorly designed screw that does not cut into box hole) to screw it into a hole in the box, cut off the other end and stripped it and connected it to the green ground wire on the transformer. The new House Door bell chime much louder with this transformer and seemed to happen faster. The chime itself requires a 10 amp transformer, so I have plenty for the RIng Doorbell Pro and the Chime. The transformer was super well packed and looks like a quality product. I also like the way the transformer has a cover over the transformer plates shielding it. The price was great too! It is UL approved and well documented. It has a internal thermal fuse (115 degrees)on the low voltage end. At night and when someone rings the bell more power is needed and this transformer is just the thing you want to avoid issues. Be aware, the electrical box where you old transformer is could have more than one live circuit running in it, so shutting off the power to the doorbell may leave a hot line inside yet. So know what you are doing. One tip is that you should cut the insulation to about 3/4-1″ on the three transformer wires BEFORE you install it to provide enough room to wrap it around the wires and not totally depend on the plastic wire nuts to hold it. And remember you are talking about 120 V circuit here, so know what you are doing and shut off all breakers for all lines in the box and test there is no power inside before starting. FYI I have a circuit breaker box tracer and wireless power tester to aid me. If you don’t know what you are doing get someone who does.

Just what I needed
I have a 40-year-old house with an antiquated low power transformer that is not compatible with most hard-wired video doorbells. This was easy to install and powers my new Ring Pro 2 doorbell. Also, like all of these units, it is made in China. However, the brand is UL approved. Some brands that may be a few bucks less, are not.

Correct transformer for newer video doorbells
I had to upgrade to this transformer for the newer nest video doorbell. The older nest hello doorbells you can use 12v and it works but the newer nest doorbell requires 16v even though Google claims 12v. The chime will not ring inside the house and you get intermittent video drop off until you upgrade to this transformer.
