Eufy E340 Doorbell UK - how to power it via mains

Hi all, since my current Eufy battery powered doorbell camera battery is getting worst I decided to get a wired camera doorbell E340. After buying it only realised that it is a nightmare to find a powering unit for it. A lot of suggestions I find are either din rails (which is not suitable) or have less power (MAs) or have noise complaints or US (110v) versions. I don’t have an existing doorbell, so the wiring or the adapter has to be all new.
What are your suggestions? Please help. Thank you.

Didnt get any responses here. And the help with this issue is very minimal everywhere for UK customers. Dont know why Eufy can’t provide apt accessories for people to buy.
I went ahead and bought below.

Have been using it for a week now. No noise. Doesnt heat up. Charges the doorbell at the moment. Only time will tell how effective this is.

Just thought of updating this so it will help someone having the same issue.

Hi
I was going to buy a transformer for my E340 but I did see some bad reviews, so I just bought another battery and swap it over when the other one is low.
