Doorbell Transformer 24V 40VA AC Power Supply Thermostat Power Adapter Hardwired Door Chime Transformer

Punched to replace low pwr transformer for Ring Doorbell.Easy installation and performs perfectly.

Great price, heat and voltage output are within acceptable levels. Durable product, standard size and great for primary power for devices that use batteries

Ours at work died after years of operation... Found this and it meets all the specs from the old one I had to remount it slightly different but in my case it is no deal breaker.. It has worked 24/7 and has not failed.. Installed in under 30 minutes.. Does not get very warm and it does not make ant humming noise, Only time will tell how long it will hold outI recommend if you need a buzzer doorbell power transformer

The transformer is fine and price is reasonable but the instructions show a different unit so that could be a problem for some folks and that is really inexcusable so deducting one star.

It took me a while to install up in attic, I move slower at 75. Had transformer installed for a week now and it works great. Ordering wat easy and it took 4 days to get them (I live in the middle of nowhere). Great transaction. Hope it lasts forever!

It doesn't work from the beginning.

Great product👍🏻

I am using this to replace a 16 volt transformer to power a Reolink Video Doorbell. It appears to be working and continually powers the doorbell. I wish I had bought the Reolink battery version WiFi doorbell but this non-battery version is working flawlessly with this transformer.
