Extended Playtime with Enhanced Battery: Enjoy up to 3 extra hours of gaming with KIWI design battery pack. Play longer without worrying about power running out—designed for maximum performance, tailored to your needs. (Tips: Battery life is affected by the usage environment and usage mode. It is recommended to avoid long-term high-power applications.)
Dual Fast Charging: Charge both your K4 Boost and Quest 3S/3 at twice the speed. Fully recharge in just 2.5 hours with a 45W adapter (not included). Get 65% charge in 60 minutes for 2.5 hours of playtime.(Both HMD & K4 Boost)
Tighten the Headstrap for a Secure Fit: The lightweight battery pack largely reduces the weight on your head by balancing the front and rear of the head strap. Simply turn the rear knob or pull the adjustment VR accessories to snugly fit the virtual reality headset to your head, so you can enjoy gaming without worrying about discomfort.
Comfortable & Balanced Design: The enlarged rear support and thickened padding reduce facial pressure, while a balanced weight design eases strain on your head and neck. Fine-tune the wearing angle up or down to find the perfect position that balances the front and rear weight, ensuring a more comfortable fit.
Safe, Reliable, and Easy to Use: Built with high-quality materials and multiple safety features, including NTC and UL certifications. It’s easy to wear with quick-adjust dials and a 52-degree damping hinge, making it simple to share with family and friends.
