Adjustable Head Strap & Battery for Meta Quest 3/3S with Recharge Battery Pack 2x8000mAh

【Dual HOT-Swap Battery Pack】Equipped with two 8000mAh batteries that you can easily swap while gaming, giving your Quest 3 over 4 extra hours of gameplay. Stay immersed in the VR world without interruptions.
【Cycle Power Supply System】The charging dock can charge two batteries simultaneously, allowing you to charge one while using the other. Swap them out and keep your Quest 3 powered up without any interruptions.
【Adjustable Support Arms】The two side arms not only adjust the wearing angle by 180°, but can also be lengthened or shortened through the rear knob. This allows for easy and secure fitting for adults, children, and those wearing glasses.
【High-Density Memory Foam Strap】The top load-bearing strap is made of high-density memory foam, providing a better fit to the contours of the head and evenly distributing and balancing the pressure from the front and back.
【Ergonomic Design】The head strap with the battery pack has a comparable weight to Quest 3, achieving improved front-to-back balance and significantly reducing facial pressure, resulting in a more comfortable gaming experience.
