In the event of an unexpected power outage, DJI Dock 2 can operate independently for over five hours using its built-in backup battery,* allowing ample time for the aircraft to return and land safely. However, after a power outage, certain functions, such as aircraft charging, air conditioning, dock cover heating, and wind speed gauge heating, are not supported by DJI Dock 2. We advise you to address any malfunctions promptly. *The duration is measured with a fully charged backup battery in a 25°C (77°F) environment.
