BOJACK Doorbell Transformer 16V 30VA AC Power Supply Thermostat 16 Volt 30VA Power Adapter Compatible with Ring Video Doorbell Hardwired Door Chime Transformer

I purchased a Doorbell camera, and could not get the chime to work with my existing transformer. I took a look at my transformer and it is only a 10VAC transformer. Works fine for conventional doorbell chime. I was curious if the 10 VAC was low for the camera. The camera works fine on the 10VAC transformer, but the chimes did not work.For kicks, decided to buy this transformer to see if it would make a difference. Sure enough...installed this transformer, and the chimes immediately started working with the mechanical chime adapter.The open circuit voltage on my original transformer was 16VAC, while this one is approximately 19.5 VAC (measured with a good Fluke DMM). As far as the transformer itself, it was perfect, three wires (black, white, green), mounting nut was provided. Seems well made, rivet is correctly pressed, laminated plates all look aligned, ground wire is installed between the body and the core. All good. installation took 10 minutes. An interesting observation is that they used Philips instead of slotted screws, but that's not a dealbreaker.

This is exactly what I needed to enable my doorbell camera to work properly. The original transformer that was installed in my house was, I think, only 12v. The lower voltage of the old one kept giving me connection problems and wouldn’t ring properly. I kept having to reset the doorbell camera. Now that my brother-in-law installed it, my doorbell and its camera work perfectly.

Perfect upgrade to the original door bell transformer. Now my wired Ring door bell pro works perfectly.

After I installed a new Wyze V2 doorbell camera, my doorbell chime would no longer work. The transformer that powered the doorbell was an older 16v 10va unit. I replaced the older unit with this 16v 30va transformer and everything works perfectly now. It is easy to install if you are a do it yourself person and comfortable working with electrical wiring. Shipping was fast and the price was right.

worked as designed on my furnace system

This solved the problem where my Google doorbell would ring outside but not actuate the indoor mechanical chime box. Thanks!

Like I said, it rings my bell. Its a good solid transformer and has enough output to handle the job.I recommend for replacement when needed or new systems.

This transformer only worked for 5 minutes then quit working. I bought it for my ring doorbells (I'm a master electrician so I know how to hook it up properly), because it has more voltamps than my original one. It was to good to be true for the price. Piece of junk.
