Doorbell power transformer 24V 500MA, AC230-240V to AC24V ring doorbell adapter, compatible with visual doorbell and thermostat (with 8M extension cable)

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

Bought to reduce the battery consumption rate of my Blink Doorbell, connected up no problem - couple of hints for others using Blink - in the app select 'Mount with wiring' and follow the instructions, when selecting the type of doorbell, select 'Analogue', and allow it to do the chime test and finally it will measure the voltage and current to check it is supplying the doorbell with the right voltage. It is important not to select 'Digital' chime as this step doesn't do a voltage or current measure and your doorbell won't run off the external power.You can verify the Doorbell is running from external power as it will show 'External Power Status' and 'Good'.

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.

Easy to fit

I ordered this doorbell transformer for my camera doorbell so I wouldn't have to charge it manually. The item arrived quickly and was well packaged. My electrician installed it and it was straight forward. It worked fine for just over two months and now no longer charges my doorbell. I tested the doorbell and it charges fine when you manually charge it via USB cable so I can only conclude that this transformer is bad quality. I have to say it's rather disappointing and conveniently falls outside the return period. A waste of money and I would definitely NOT recommend!I hope you found this review helpful.

Not needed as the Ring Doorbell I bought it for is utterly useless

100% Happy with the item and good value for the money

Did the job works fine nice long cable

El transformador es para UK pues no para EU, que tonto.entonces estábamos obligatorio de buscar una enchufa de cambiarlo. Que mal, nunca mas voy a comprar cosas en Amazon.
