Customers say
Customers find the doorbell power adapter easy to install and appreciate its more than adequate length. The functionality receives mixed feedback – while some say it works great with Ring doorbells, others report it stopped working completely after two months. Moreover, the battery life and voltage performance are problematic, with customers reporting the battery level dropping and no voltage at the connector end. The power adapter’s value for money is also mixed, with several customers finding it not worth the cost.
