Ring Doorbell Transformer Compatibility

Hey Folks

So I had a Ring Pro Doorbell for the last 3 years but it packed in so ended up binning it and replacing with a Eufy 2k Battery powered doorbell. The ring was hardwired using the transformer they provide. So I basically did a straight swap with the Eufy and connected the wires up to it. It was charging fine etc but today I’ve noticed my doorbell is off due to low battery, 15 days after installing. Does the voltage output need changing at the transformer, or is it the same?

Thanks in advance
