I have installed the Eufy E340 Video doorbell, hard wired to a transformer that also powers the security alarm. The transformer outputs DC20 V 1.5A.
The problem I am having is the doorbell does not charge the battery once it drops to around 80%. I have been charging the battery using the USB cable which is too inconvenient. I have raised a ticket with Eufy, who passed me onto their Australian support, who have not even responded with a resolution for the problem. Would appreciate any advice from members that have had the same problem. Thanks in advance.
Hi ! electrician here I tend to agree with JD164 probably a power issue. I know they says the door bell camera has a voltage range. with out me looking up probably 8-20 volts but most residential alarm systems are feed with a 24 volt transformer so that could be the issue maybe overcharging protection. My DB camera uses the original 16 volt from the house chime and it also rings the house unit. I have never had any issues and it definitely charges. Good luck with the replacement Eufy is good with that I had a problem with a camera and they had Amazon send a new camera and it came the next day.
Thanks for your response to my issue. Attached is a picture of the back of the doorbell power specs.
I have let the battery drop below 80%, 50% and 5% before charging via USC cable. The power indicator does not switch on.
I have tried following up with Anker/Eufy, they seem to have closed the case and do not want anything to do with resolving the problem.
Thanks in advance

Okay, the doorbell says it can operate with a wired voltage of 8 to 24 volts alternating current (AC).
You need to find out what type of current your transformer supplies /it’s output.
Is it DC direct current or AC alternating current. The doorbell requires alternating current AC.
Are you able to visibly see the specs written on transformer?
If you do have alternating current AC, then it may just be an issue with the transformer unable to supply enough VA Volt Amp to charge the battery.
