Yes, it is possible to leave the eufyCam 3 permanently connected to the power supply, although this requires some consideration.

- The camera can be powered via the USB Type-C port on the back with a power adapter and USB-C cable, which enables permanent charging.
- However, it should be noted that the camera is normally designed for battery operation and the integrated solar panel provides a self-sufficient power supply. A permanent connection to a power supply unit cannot be harmful as long as the settings in the Eufy app are adjusted accordingly.

It is advisable to check the settings in the app and ensure that the camera is configured correctly to ensure a permanent power supply.
