Compatible With Quest 2: The gravity balance and distributed design is adopted, so that the gravity of the product is evenly distributed in different positions of the head, reducing facial pressure. The design is adjustable with 5 different nodes, which can be freely adjusted to the most comfortable state to adapt to different sizes of head shapes Power supply is more convenient: The battery pack adopts a magnetic quick-release design, and the battery can be detached and charged, which does not affect the use of VR host. Two battery packs are hot-swappable for unlimited battery life (the second battery pack needs to be purchased separately); Reducing the weight of the head battery: We designed a dedicated battery pack B2 for the VR host, which weighs only 140g, which can balance the front and rear weights. Compared with the traditional power bank, the burden on the head is significantly reduced; Double the battery life: The battery capacity of a single battery pack is 5200mah, which can fully charge the Quest2 once, adding about 2-4 hours (APP depends) of VR time, and there is also a USB-C interface. Can power other accessories like BOBOVR F2. Hassle-free Warranty: For any pre-sale or after-sales issues, an 18-month hassle-free warranty is guaranteed to feel free to contact us.
