Head strap with 5300maH battery KIWI design K4 Boost for Meta Quest 3/3s

The KIWI design K4 Boost's 5300 mAh battery provides up to 3 additional hours of playtime on the Meta Quest 3/3s - ideal for virtual reality fans who want to get the most out of each session. Thanks to its balanced design, the strap reduces pressure on the face, increasing comfort and allowing for prolonged use without fatigue.

The DualBoost system allows simultaneous charging of the battery and Meta Quest 3/3s. Using a 45W adapter, charging is twice as fast as with standard solutions. As a result, a full charge takes just 2.5 hours. With a maximum output power of 25W, the battery provides stable charging, allowing longer gaming sessions without interruptions.

The K4 Boost strap is designed to distribute weight evenly on the head, reducing pressure on the face. A knob allows for quick adjustment, making the accessory a perfect fit for different head sizes, ensuring comfort even when lying down. The hinge allows the product to tilt 52°, allowing for easy donning and doffing. Soft cushions on the back gently support the head, increasing stability.

The product meets strict safety standards, offering more than 10 levels of protection, such as protection against overcharging, overcurrent, overheating and overvoltage. It is made of flame-resistant UL 94 V-0 material, guaranteeing safe use even during intensive sessions. The high level of quality is confirmed by relevant certifications.
