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

Arrived quickly, easy to connect and works as expected. Great to not have to keep taking the doorbell off to recharge it. No instructions but easy to fit, wires can be connected either way round.

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.

Buying this power adapter has been such a time saver and stress free purchase because it removes so much of the anxiety of the battery running out then having to charge it during the day etc. I did have drill a hole through my front wall to feed the cable through but it was well worth it. The adapter does make some coil noise however it doesn’t bother me because it is in the front room where no one usually is. Great compatibility since it uses generic power cables for doorbells and it is a trickle charge so bear that in mind. It doesn’t keep the battery fully topped up. However you doorbell won’t ever die on you again

Hi, this does not work on a eufy e340 door bell.. initially it will work but then you will notice the bell has switched off because the battery is not charging then you will get a not compatiable warning and it wont allow you to set the recording times. Avoid ive tried 4 different brands 24v 500ma ac 16v then another 24v then finally another 16v. The adaptor itself becomes really hot. Avoid

I already had this model fitted but damaged the wire on it, but the new one just like the last is silent and reliable.

Works well for Ring doorbell. Easy to install.

Easy enough to install and works ok with my Eufy 2k video doorbell. BUT the transformer is so noisy!! I read in the product description that the manufacturer had worked to eliminate any noise. Have I got an old one??
