Battery Usage Time Information

NOTE: 

• When the projector is in use, a 5V/2A power adapter is required to fully recharge the projector.
• When the projector is in use, using the USB A port to power other devices, e.g. wireless dongle, may prevent the projector battery from being fully recharged.
• When the projector is in use with a low battery status, using the USB A port (2.5W), even if the power adapter is plugged in, the projector may turn off or restart automatically. If this occurs it is suggested to remove the USB A connected device and let the battery fully charge.
