Ring Doorbell 2 - wont charge

I purchased 2 of the Ring Doorbell 2, i have them mounted and purchased 2 differnt AC adapters for these units. I cannot get either one to charge properly, have mounted and demounted 4 times now and tried 2 different adapters from Amazon that others are having success with. Proper voltage from both units beins supplied.

Hey @cdennste. We do not have any certified power supplies to help keep the Doorbell charged, like the Plug-In Adapter that we have for the Doorbell Pro. If you are using a 3rd party adapter to see if it can help charge your device, this may be why it is not working.
