KIWI design K3 Boost Battery Head Strap Compatible with Meta Quest 3/Quest 3S, 6400 mAh Battery Pack Head Strap Accessories, Fast Charging & Reduce Face Stress

When I purchased this headstrap and battery combo I was looking to improve on the original Quest 3 comfort. I looked around online for a decent headstrap and kept finding people were getting better results when a battery pack was helping distribute the weight from the overly front heavy HMD. I saw that this product by Kiwi had lots of good reviews and for the price, decided to give them a chance. I must say, I don't regret it at all! It in fact has been a great little addition to the Quest 3. I'm writing this review over 1 year after purchase, and I can't stress I am very pleased with it. Fits great for me, makes the HMD better balanced which improves stability. Not to mention it was at a great price when compared to Meta's version. The head strap has a padded area that helps with improving fit and comfort, as well as at the back of the head. Over a year now with it and it still providing extended times. I'm not a heavy user though and never took the time to track how much additional time it gives, but it is much more than the standard headset provides. I know that much because I've been in situations where I learned the hard way about the Quest 3 desire to stay on despite shutting it down which left me only the HMD's internal battery to use. That, did not last long the times I've used it as such. So I was surprised on several occasions when I picked up my Quest 3 and saw the HMD was running on its own internal battery. The Kiwi battery was discharged. I found it weird because I left it fully charged over night before unplugging the Kiwi battery from the wall charger. Little did I know that what happened was that the HMD after being shutdown, continues to operate a state of charge indicater, while it remains plugged to a power source. That is, because the battery was plugged to the HMD (the Quest 3), the HMD considered it a regular charger and continued to run the face sensors and battery SoC sensors. If you activated the sensor by using a cover on the lenses you would even activate the display. My thoughts are that the designers realized they have no external way of showing SoC of the battery on the Quest 3. So they decided it would just turn on the screen to show you the SoC of the battery. The point is, because the battery was plugged into the HMD the HMD did not fully shutdown draining the battery. Once I found out about that I began unplugging the battery from the HMD when I was done. Which pretty much solved that issue instantly. That is by far not a problem from this product but rather a behavior of the Quest itself. Now, again, I'm not the most verse individual with the Quest 3 but I know a thing or two, so I'm almost ashamed to admit I didn't really learn thoroughly my Quest 3. It took me forever to learn about the facial interface and how it can be adjusted for things like wearing glasses. I had a period of use with this headstrap and battery where I still felt as if the weight was heavy on my face. Almost like I wasn't getting even distribution. I felt the pressure most on my nose. I adjusted the distance between the eyes several times to see if I was just pinching it. Well, when I finally found out about the facial interface adjustments I immediately felt the results. No more pinched nose and the weight seemed to lift off my face. Before, using the original straps, the headset felt when loose like it would slide down my face and when tightened it felt like it would pop off over my head. With this, the headstrap feels well placed on my head and doesn't feel like it would either fall or pop off. I highly recommend it for anyone with a Quest 3 (I can't speak for any other Quest, I only own the 3).

This thing is way more comfortable than the factory strap. The battery at least doubles Quest 3 play length. Charging the battery while it’s plugged into the headset is awkward. Can charge all night and both are still charging in the morning so I just plug each in directly. Had it for maybe a year? And it is durable and easy to clean. Very well balanced with the headset. Overall 9/10. Works great, charging doesn’t passthrough well.

I am writing this review to shed some light on products such as the battery head straps for the quest headsets. A lot of people have a misconception on how these headset batteries work so I am here to shed some light on that. These battery packs IN NO WAY CHARGE YOUR HEADSET WHILE YOU PLAY! THEY INFACT EXTEND BATTERY LIFE FOR ABOUT 3-5 HOURS DEPENDING ON HOW DEMANDING YOUR GAME IS. The Kiwi head strap is absolutely great, I am able to play my quest headset for about 5-6 hours gameplay IN ALL compared to the 1.5 hours gameplay without the battery strap. Granted every battery head strap I’ve owned takes a while to charge this one has my other batteries beat when it comes to recharge 30 mins it charges one column light so on all it might take you 1-2 hours to get a decent amount of charge. How it works is that while you are playing the strap battery is getting used up before the main battery. WITH THE EXCEPTION THAT THE MAIN BATTERY MIGHT GET DRAINED ABOUT 10% AND THE MAIN BATTERY WILL KICK ON AT 90% ONCE THE HEADSTRAP BATTERY DIES. I get about 2-3 hours EXTENDED SO 5-6 HOURS game play before the head strap dies on population one. And about 2 hours extra playtime when playing Real VR Fishing SO IN ALL 4-5 HOURSE GAMEPLAY. Yes it takes a while to recharge. If your playing your headset for over 10 hours touch some grass for once in your life. I play my headset everyday and I do sometimes hop back in before the battery is recharged. But over all for how much this Head Strap is and the quality of the battery and comfort I 100% recommend this head strap and it’s 100% worth the investment. P.S the amount of power you need to run vr is massive so the battery time this Kiwi Head Strap battery takes to charge is average for it is larger than a portable battery you would use for your phone. Happy gaming!

I tried a couple of others, sent them back and finally got this one. It adds a solid 2+ hrs of gameplay using 80% brightness AND AR passthrough on the Quest 3, and over 3hrs of gameplay with 50% brightness and no AR passthrough. (Tested on Synthriders). The quality is excellent, it's not too heavy, even the packaging was of surprisingly good quality. From the moment I opened the box I had a feeling this was a much better item than the others I'd used. It is comfortable, doesn't fall off during vigorous gameplay, and is adjustable using the strap on a tightening wheel on the back for quick tightening and release. It came pre-charged at around 70%, which all lithium batteries should. A few other brands I bought came empty or less than 10%, which indicates poor battery quality or poor storage. I would definitely recommend this add on for the quest 3.

Ich war auf der Suche nach einer Möglichkeit, mein VR-Erlebnis mit dem Meta Quest 3 zu verbessern, und der KIWI design Elite Strap mit Akku 6400mAh hat alle meine Erwartungen übertroffen. Dieses Zubehör ist ein wahrer Gamechanger für lange Spiel-Sessions, da die eingebauten Batterien in Industriequalität die Spielzeit tatsächlich um 2-4 Stunden – je nach Belastung – verlängern. Es ist beeindruckend, wie viel länger ich jetzt in die virtuelle Realität eintauchen kann, ohne mir Sorgen um die Akkulaufzeit machen zu müssen. Neben der verlängerten Spielzeit bietet der KIWI Elite Strap einen luxuriösen Tragekomfort, der seinesgleichen sucht. Die weichen, dicken Polster auf der Ober- und Rückseite zusammen mit dem perfekt ausbalancierten Akkupack und dem ergonomischen Design sorgen dafür, dass ich auch in längeren Sessions keinen unangenehmen Druck auf meinem Kopf spüre. Die Polsterung aus Formgedächtnis-Schaumstoff ist nicht nur extrem bequem, sondern auch sehr leicht zu reinigen – ein echter Pluspunkt für mich. Der vergrößerte Kopfbügel passt sich zudem problemlos an verschiedenste Kopfgrößen an und erleichtert das Tragen des Helms über längere Zeiträume erheblich. Dass der KIWI Elite Strap zudem mit einer zertifizierten, sicheren und langlebigen 6400mAh Batterie ausgestattet ist und der Gurt umweltfreundlich und robust gestaltet wurde, gibt mir zusätzliches Vertrauen in dieses Produkt. Es ist klar, dass bei diesem Elite Strap sowohl Sicherheit als auch Komfort großgeschrieben werden. Es mag zwar nicht mit dem vertikalen RGB-Ladeständer kompatibel sein, aber dies tut der hervorragenden Gesamtleistung keinen Abbruch. Fünf Sterne und eine uneingeschränkte Empfehlung für jeden Meta Quest 3-Besitzer!

Ce module pour casque VR est vraiment sympa il rajoute de l'autonomie et du confort!!!

メガネをかけて利用する私に取って、標準のゴムのヘッドストラップに比べて、装着時の負担減はかなり大きいです。 耳部分が跳ね上げられるようになっているので、メガネをかけてゴーグルを合わせた後に頭の部分を下ろすというやり方で、格段に装着時のストレスが軽減しました。 また、装着している時の快適性も抜群で、バランスがよく、ゴーグルのずり下がりがないのでよりVRの世界に没頭できます。 さらにバッテリーまで内蔵しているので、連続での使用可能時間が体感ですが3倍以上になったように思います。 これからも長くMeta Quest 3/3Sを愛用しようと考えている方には断然導入をおすすめします。 ※注意点 後頭部にバッテリーがある構造上、寝転がってYoutubeを見る等には適していません。寝転がって利用したい時には標準のヘッドストラップに付け替える必要があるのはひと手間かかります。

Battery lights remain on after 4-5 charging sessions (same as other users are having here) and it never charges Meta again. Do not waste your money on this.
