Should be ok as the name plate shows it having a voltage range 110-240 and 50/60hz I.e dual voltage/freq. Moving from USA to uk I’ve had to scrap about 50% of my electrical goods because some were 110 only but the dual stuff is fine. I think ring have 1 sku for the chime and just change out the removable plug pin piece (the photo in my original post). But that removable part doesn’t appear to be available as a spare part unfortunately. Ring guy told me just to be an adapter from amazon. Thanks anyway
