KIWI design K4 Boost Battery Head Strap for Meta Quest 3/3S

Overview

The KIWI Design K4 Boost Battery Head Strap (KW-QS02B) is a purpose-built upgrade for Meta Quest 3 and Meta Quest 3S owners who refuse to let a dying battery cut their VR session short. As an officially Made for Meta accessory, it integrates seamlessly with your headset — delivering an extra 2.5 to 3 hours of playtime from its 5,300 mAh (20.4 Wh) built-in battery, all while improving balance and reducing the pressure your face bears during extended wear.

Whether you're deep in a VR fitness routine, an immersive game, or a social experience, the K4 Boost keeps you in the action — and back to full charge faster than you'd expect thanks to its intelligent DualBoost charging system.

Key Features

• 5,300 mAh Built-In Battery: Adds approximately 2.5–3 hours of additional playtime to your Meta Quest 3 or 3S on a single charge.
• DualBoost Fast Charging: With a 45W adapter, the strap and headset recharge simultaneously — both fully topped up in around 2.5 hours, with up to 25W delivered directly to the headset.
• Ergonomic Rear Counterweight Design: The rear battery placement acts as a natural counterbalance, shifting weight off your face and reducing pressure fatigue during long sessions.
• Thicker Cushion Padding: Enhanced facial padding provides a softer, more comfortable seal compared to the stock Quest 3 strap.
• 52-Degree Damped Flip Hinge: Flip the headset up away from your face in one smooth motion without removing the strap — perfect for quick real-world check-ins.
• Quick-Adjust Dial: Dial in your ideal fit instantly with a precision rear-adjustment wheel, accommodating a wide range of head sizes.
• Certified Safety Standards: The battery and charging system meet UL, EN, and FCC requirements, so you can charge with confidence.
• Made for Meta: Officially certified for Meta Quest 3 and Meta Quest 3S, ensuring reliable compatibility and performance.

Who It's For

The KIWI Design K4 Boost is ideal for dedicated Meta Quest 3 and 3S users who regularly hit the stock battery's limits — gamers, VR fitness enthusiasts, developers, or anyone who spends meaningful time in virtual reality. It's equally valuable for anyone who finds the default head strap uncomfortable over time, as the ergonomic rear support and improved padding make a noticeable difference even before accounting for the extended battery life. If you want a single upgrade that tackles both comfort and endurance, the K4 Boost is it.
