Eco Mode is designed to protect the projector from sudden power outages. Due to the different models and protocols of power banks, we can’t guarantee that all power banks can consistently supply power to our machine. Therefore, we have an Eco Mode, which limits the screen brightness to 40% .It does not limit the volume.For increasing the using time,it's recommended to set the volume no more than 50% under ECO mode.
Users can manually turn off Eco Mode by going to "All Setting" -- "Display&Sound" -- "Picture" -- "Brightness Mode" -- "Eco Mode".
