How H4 Boost Achieves a Balanced Lightweight Design
In designing a battery head strap, the balance between battery life and weight has always been a main concern for users. Through optimizing the design of battery and structure, the KIWI design H4 Boost strikes an ideal balance between battery life and weight. This article will explore how the H4 Boost improves user comfort while ensuring ample battery life.
Balancing Battery Life and Weight: The Need for Weight Reduction
In daily VR use, most users find 2-3 hours of battery life sufficient. Traditional battery straps tend to use high-capacity batteries to extend battery life, often achieving 4 hours or more. However, this comes with a trade-off: significant added weight. With a 400g VR headset combined with a 500g battery strap, users experience increased neck strain and discomfort.
To address this issue, KIWI design’s R&D team conducted market research and lab testing, finding that a lightweight design can significantly enhance comfort and reduce neck strain during extended wear.
Weight Reduction: Battery and Material Optimization
-
Battery Choice: Efficient Lithium Cobalt Oxide Battery
-
The H4 Boost uses a 5300mAh lithium cobalt oxide battery. Though it provides slightly less battery life(3 hours) compared to the standard 10,000mAh battery, its high energy density reduces the overall weight of the head strap by about 100g.
-
Lithium cobalt oxide batteries are not only lighter but also offer higher conversion efficiency, allowing the battery to deliver effective runtime without adding extra weight to the user’s head.
-
-
Material Choice: Lightweight and Durable Structural Materials
-
KIWI design incorporated high-strength, lightweight materials in the H4 Boost’s frame to ensure stability and durability.
-
A hollow and ventilated structure reduces overall weight while enhancing breathability, making the head strap comfortable for long sessions.

Advantages of 3-Hour Battery Life: Meet Actual User Needs
The 3-hour battery life is tailored to match VR users’ typical usage patterns. For most users, a 3-hour session aligns closely with daily gaming durations, making the H4 Boost’s battery life more than sufficient. At the same time, its lightweight design improves comfort during wear.
Additionally, the H4 Boost features DualFast Charging (DFC) technology, dramatically increasing charging efficiency. During short breaks, users can quickly recharge, further enhancing the experience.
How H4 Boost Achieves Reasonable Weight Reduction: Multiple Considerations and Balance
-
Balancing Weight and Health
-
A lightweight design makes extended wear more comfortable and helps reduce long-term strain on the neck. The H4 Boost’s weight reduction is carefully engineered to support user health.
-
-
Balancing Battery Life and Comfort
-
The 5300mAh battery was chosen as an optimal balance between battery life and comfort. Unlike heavier batteries, the H4 Boost provides sufficient battery life for most use cases without compromising wearability.
-
-
Balancing Fast Charging and Efficient Battery Life
-
With DFC fast-charging technology, users can quickly recharge the device within a short time. This innovation minimizes the need for a larger, heavier battery, achieving efficient weight reduction.
-
Conclusion: Reasonable Weight Reduction for an Enhanced VR Experience
Through precise weight reduction, the H4 Boost achieves an ideal balance between 3 hours of battery life and lightweight comfort. This design not only enhances wearability but also improves overall user enjoyment. Moving forward, KIWI design will continue to explore innovations in lightweight, ergonomic VR solutions, bringing users a smarter, more user-friendly VR experience.
