Kiwi design H4 Boost Halo Battery Strap: One-minute review
At $99.99 / £82.00 / AU$161 this Kiwi design H4 Boost Halo Battery strap is not cheap. But if you use your VR headset frequently it could be a worthwhile upgrade to your Meta Quest 3 or Meta Quest 3S – it’s already become my favorite Quest 3 accessory.
The built-in battery – the main reason to buy this strap – boasts a 5,300mAh capacity, which is a little more than the battery life of either the Quest 3 or Quest 3S. This doubles your VR and MR sessions, an advantage anyone who has ever had to cut a session far too short because their battery ran out will appreciate.
Beyond direct utility, the battery strap helps improve your Quest setup’s comfort to some degree as it serves as a counterweight to the headset proper and includes front and back padding. With its adjustable hard plastic mechanism, the strap will also remain comfortably attached to your head providing a more stable fit than the strap you get with your Meta Quest 3.
The only downside is that the strap weighs 446g, which is about 60g shy of what the Quest headsets weigh on their own. So while the battery is useful, a non-battery-equipped head strap like the H4 Halo Comfort (which is otherwise identical to the H4 Boost Halo) could be a better pick if you find your headset is heavy enough as it is.
Kiwi design H4 Boost Halo Battery Strap: Price
- Normally costs $99.99 / £82.00 / AU$161
- Regularly on sale for less
At $99.99 / £82.00 / AU$161 this Kiwi design H4 Boost Halo Battery strap is not cheap. But if you use your VR headset frequently this cost could be worthwhile as the strap effectively doubles how long you can use your Quest 3 for between charges.
What’s more, Kiwi design’s accessories are frequently on sale on Amazon and its store. We’ve seen it drop as much as 40% during sales so it’s worth waiting for a discount unless you’re desperate for a Quest 3 upgrade.

Kiwi design H4 Boost Halo Battery Strap: Design
- Comfy and secure Meta Quets 3 or 3S headstrap
- Doubles your Quest headset's battery life
The Kiwi design H4 Boost Battery Halo head strap can easily replace the base head strap included with your Meta Quest 3 or Meta Quest 3S – just unclip and unloop the original, and attach the H4 in its place – and it’s a near-total upgrade.
First, the hard plastic strap is adjustable and has cushioning on the back and front of your head which combine to create a more secure and comfy setup than the basic Quest head strap. Second, and more importantly, it comes equipped with a battery that increases how long you can use your Quest 3 between charges and can be easily connected to your headset via a built-in USB-C cable.
The battery – which is housed at the back of the head strap and serves as a counterweight to the headset proper, improving comfort – boasts a 5,300mAh capacity.
This is just over the battery capacity of both the Quest 3S (4,324 mAh) and Quest 3 (4,879 mAh) so your headset’s battery life will more than double; if you got 2 hours of usage out of your Quest you’ll now get 4 hours.
Best of all, with your headset hooked up to the battery pack you can use a USB-C cable to charge the pack and headset simultaneously, and fairly quickly, too. Kiwi design promises that a 45W charger can restore 60% charge to your headset and 65% to the strap in an hour.
In my experience, the setup does recharge fairly speedily, and the extended battery is more than enough to game for a whole evening without needing to take a break for my headset to recharge – which is a frustration I’ve dealt with in the past.
The only notable downside is that at 446g this head strap is just 60g lighter than either the Quest 3 or Quest 3S on their own, doubling your setup’s weight as well as its battery life. If you already find your headset is too heavy as is then adding this strap could be a bad idea.
However, during my testing, I never had trouble wearing the H4 Boost Halo Battery strap for an extended play session, so I expect many VR users won’t struggle too much with it either.
- Design score: 5/5
Should you buy the Kiwi design H4 Boost Halo Battery Strap?
Buy it if…
You wish your headset could go the distance
If two hours of battery life per charge is never enough, then this battery strap will go a long way to solving your Meta Quest 3 or Meta Quest 3S woes.
You want comfort
If the regular Quest 3 head strap isn’t comfy or secure enough for you then you’ll appreciate the cushioning and adjustable design of the Kiwi design H4 Boost Halo Battery Strap.
Don’t buy it if…
You use your headset infrequently
The H4 Boost Halo Battery Strap is excellent, but it’s not good value if you use your VR headset infrequently. If you’re new to VR wait and see how often you use it before upgrading to this head strap.
You find your headset too heavy already
This strap effectively doubles the weight of your Quest 3 setup. The battery acts as a counterweight to keep it from feeling too uncomfortable, but it’s something to consider if headset weight is already an issue for you.
How I tested the Kiwi design H4 Boost Halo Battery Strap
To put this strap through its paces I used it for a few weeks with my Meta Quest 3 and made sure to swap back to the base strap every so often to get a sense of the advantages and disadvantages of each design. I also compared it to the Razer head strap and the K4 Battery strap from Kiwi to judge its effectiveness against other third-party headsets.
