TechRadar tested the Kiwi Design K4 Boost Battery Strap, evaluating its price, design, and performance to determine if it’s a must-buy. From a design standpoint, this battery-operated headband may not be as striking as Kiwi Design’s H4 Boost Halo Battery Strap, but it still fulfills a lot of requirements.

Design and Fit: Comfort Meets Practicality

Compared to the standard fabric strap that would have come with your VR headset, the cushioning and adjustable plastic provide a secure yet comfortable fit, and its 5,300mAh battery capacity effectively doubles the power life of your Meta Quest 3 or Quest 3S.

Value for Money: Affordable and Accessible

The best part is that it only costs $69.99, £57, or $113. Because of this, it’s a reasonably priced option that’s ideal for new or casual Meta Quest players who want something useful but aren’t ready to spend a lot of money on expensive upgrades.

Typically, it costs $69.99, £57, or $113 and is usually lowered during sales events like Prime and Black Friday. The Kiwi design K4 Boost Battery Strap costs $69.99, £57, or AU$ 113 when purchased from Kiwi Design’s official shop or Amazon, though both stores sometimes offer discounts.

When compared to the competitors, the K4 Battery Strap performs admirably in terms of design, with only a few minor drawbacks. Check the latest VR testing video for more design information. 

Choice of Buy

For users of Meta Quest 3 on a tight budget who want to prolong their play sessions, the Kiwi Design K4 Boost Battery Strap is an excellent option. It essentially doubles the power life of the headset, which makes it perfect for extended VR and MR experiences. 

However, because this strap adds a lot of weight, it might not fit your Quest 3 the best if it already feels too heavy. Additionally, in comparison to more expensive choices, its flexibility may be inadequate for individuals looking for a luxury experience. However, if weight isn’t an issue, this strap is among the greatest reasonably priced accessories out there.
