The usage time in video mode is 2.5H, in JBL speaker mode, it's 18H. Please note that the screen brightness will be reduced in battery mode to prolong usage time. You can adjust the brightness in setting if you needed. *************** Maintaining high brightness may result in a slightly lower duration than 2.5 hours. 3.Watch Netflix on T2? Due to copyright restrictions, most projectors, including T2, can't directly mirror streaming services. Use HDMI or USB instead. We'll launch an exclusive T2 TV Dongle on July 25 (sold separately), with details updated on the product page. Meanwhile, consider other affordable TV sticks for a seamless viewing experience. 4.T2 Include Remote Batteries? Starting with the second shipment, we added two AAA batteries. For owners of the first batch of T2 projectors, reach out to us to obtain them! 5.T2 Usable Outdoors Daytime? Although the T2 weighs 2.4 kg (about 1.8x the length and 1.5x the width of an iPhone)compared to similar devices in its price range, this is due to its high-capacity battery and uncompromised brightness. This makes it an excellent choice for camping and outdoor movie watching. However, due to brightness limitations, it may not perform as well in daylight or brightly lit environments as it does at night or in darker settings. Please choose based on your specific needs and usage scenarios. 6.About Auto Focus & Keystone? Auto-focus and auto-keystone work best when the projector is within 15° of the wall. Greater angles may affect performance. Use electric focus and 4P keystone correction for large deviations. Attention：Ensure the focus receiver at the bottom is not obstructed to maintain auto-focus. 7.About Auto Obstacle Avoidance? Before using the auto obstacle avoidance feature, make sure the auto keystone and auto focus functions are turned on. Obstacle avoidance may not be possible when there are white or other light-colored objects in the target screen.If you have any questions, please let us know immediately. 8.Regarding the Power-On Issue? Due to long transportation, the battery may have lost some charge and might not show as fully charged when you turn on the projector for the first time. This is normal and workable. Try holding the power button on the projector panel for 5 seconds to turn it on. 9.About Screen Alignment? When using screen alignment, please note the following: 1)Before using the screen alignment function, make sure that the automatic keystone correction and auto focus functions are turned on. 2)The screen with a white background should have a black or other clear border3)The projected image needs to be larger than the screen area before the screen is adapted.4)When using this function, please do not block the center of the screen.
