Being lightweight is our core proposal, the key to the OPPO Pad Air's exquisite appearance and comfortable in-hand feel, as well as one of the core OPPO elements. OPPO Pad Air guarantees full-day continuous usage for work, entertainment, and online classes with a 7100mAh big battery. The user can connect the tablet to OPPO earphones via Bluetooth to enjoy 3D surround sound (the video needs to support Dolby sound effects/Dolby Atmos). Dynamic sound effects can be generated based on the video content, creating more authentic 3D surround sound. Looking at LCD screens for a long time may cause eye fatigue. Some eye diseases may also arise over time, such as retinitis and decreased color discrimination. Screens that have obtained the TÜV Rheinland Eye Comfort Certification can reduce eye fatigue and provide a more comfortable visual experience.
