Doorbell Transformer 24V500MA, Visual Doorbell AC Power Adapter, Suitable for Most Versions of Ring Doorbell and Thermostat (8M extension cable white)

The power supplied charges the doorbell nicely. easy to install.

Works well with Eufy S330 doorbell. Powers the Eufy doorbell, the original push door button and the original external chime.Other reviewers are right, there is a small hum from the transformer.Otherwise seems okay

This is the second one of these I’ve had now after accidentally cutting through the first one when opening the garage door. The length of the cable is great as it allows us to feed it through to outside and keep it tidy along the edges of our garage. Installation is simple, just screw the 2 attachments onto the back of your ring doorbell using the screws already on the doorbell and then plug it in. This will only trickle charge however so give your ring doorbell a good charge before hand and this will just prevent the battery going down rather than to charge it up. The only issue I’ve found with this one is the noise, it has a slightly annoying humming/buzzing sound coming from it which my old one didn’t have, luckily for us it’s in the garage so we don’t hear it from the house, otherwise I would send it back. I’m guessing this must be a faulty one given that my old one of the same brand didn’t make this noise, albeit I have read other reviews from people who have mentioned the same.

Best buy an electrician wanted £200 to wire my door bell up I got this had it a few mths before leaving a review had no issues at all very easy to use and door bell never dies brilliant

Started making burning spell after an hour of use and eventually broke down. Poor build quality and inadequate power supply to the ring battery. It did not work with Ring video door bell and while it is easy to install, it did not last.

Done a lot of online research for a mains adapter that didn't make a humming sound and this one is the best

When I purchased this transformer, it was because I didn't have a doorbell installed.So, when I bought the doorbell, I also purchased the transformer.All I needed was the transformer to plug directly into a power outlet. This setup allowed me to avoid hiring a specialist, who would have likely charged extra for the installation.Connecting the doorbell was straightforward. I installed it outside, ran the wire through a small hole in the wall, and connected the wires directly to the power outlet. It really is that simple—there’s nothing complicated about the installation.The instructions provided are very easy to follow, making it accessible for anyone to do it themselves.However, extra caution is necessary when connecting to the power source. If you're unsure, it's advisable to consult an electrician. This recommendation is also included in the instructions for those who may need professional assistance.Cable length quilt good, to connect directly to power saves me from recharging. Power converted to the level the cam needed, good quality build

ok so it doesn't work , but thats apprently because you need a special Risistor in the circuit to make it work. and also to make it safe!!Ive ordered a risistor and will let you know if it works
