Key Features

  • 20W Super-Fast Charging: We focuses on innovation in VR charging technology. The S3 Duo supports 20W fast charging for the Meta Quest 3 and Quest 3S, addressing concerns about battery life and long charging times. (According to our testing, the S3 Duo charges the Quest 3 from 0% to 100% in 2.5 hours, and the Quest 3S in 2 hours, whereas other 10W/12W battery straps take 3.5 to 4 hours to fully charge).
  • Magnetic Charging Dock: The swappable charging system offers VR gamers the most convenient and efficient charging solution, the magnetic charging dock supports 30W fast charging (up to 15W per battery pack) and stores the battery packs, say goodbye to tangled cables and low battery anxiety. The 8000mAh battery pack effectively extends your gaming time, providing an additional 125% battery life for the Quest 3 and 150% for the Quest 3S.
  • Compatibility and Safety: S3 Duo is compatible both with Quest 3 and Quest 3S. We’ve optimized the charging system to enhance compatibility with the Quest 3/3S. The battery pack supports overheating, overvoltage, and overcurrent protection, along with 4 LED indicators for battery status. Providing users with a convenient, fast, and safe gaming experience.
  • Durable and Slip-Resistant Knob: S3 Duo features a stepless adjustment knob for precise fitting. Made from high-toughness, durable material, the knob ensures long-term use without slipping or malfunctioning.
  • Exceptional Comfort and Balance: The S3 Duo features soft memory foam padding, and the back pad is made of high-toughness soft silicone, fitting various head shapes. The head strap balances the weight of the device and battery pack, reducing pressure on the face and neck, and enhancing comfort and gaming experience.
