KIWI design K4 Boost Comfort battery strap 2.5h
Product description
This battery head strap extends play sessions by adding up to three hours of runtime, improving balance and comfort for longer VR sessions with the Meta/Oculus Quest 3. It combines a rear-mounted battery with thickened padding and a quick-adjust dial so the headset feels more stable during gaming and media playback 🎮.
Key Points
The strap aims to reduce facial pressure and neck strain by moving weight towards the back and enlarging rear support. A 52-degree damping hinge simplifies putting the headset on and taking it off, and the quick adjustment dial helps achieve a consistent fit for different head sizes. The integrated battery is designed to deliver additional playtime, according to the manufacturer, so you can finish longer experiences without frequent interruptions.
Safety features include high-quality battery cells and multiple layers of circuit protection such as NTC and UL certificated components. Materials and circuitry have been tested in TUV laboratories for durability and safe operation. Do consider that the recommended 45W adapter is not included, so charging accessories will need to be sourced separately 🔋.

Usage Recommendations
If you expect extended VR sessions carry a compatible fast charger to take advantage of the 2.5 hour full recharge time and the faster 65% in 60 minutes benchmark ⏱️. Charge cycles and actual extension of playtime will vary with usage patterns, applications running and headset settings. Note that while the strap adds comfort and battery backup, it also increases the overall size of the headset so check clearance for storage or transport. 🛡️.
