The Meta Quest Elite Strap with Battery is designed for Meta Quest 3 and Meta Quest 3S users who want to spend more time in virtual reality without frequent interruptions. By integrating a 2,330 mAh battery pack into the headstrap, it provides approximately 2 hours of additional playtime, allowing you to dive deeper into your favorite experiences. A convenient feature of this system is that you can charge both the headset and the strap battery at the same time using a single cable. Constructed from a blend of plastic, fabric for the top strap, and silicone for the rear support, the strap weighs 331 g and measures 241 mm by 173.1 mm by 101.5 mm. You can easily customize the fit using the rear adjustment dial, which helps balance the weight of the headset for a more comfortable feel during extended sessions.
