Kiwi Design announced they will be releasing an alternative to the official Quest 2’s Elite Battery strap. There are loads of third-party accessories in the VR scene, but KIWI’s accessories are known as some of the best.
While the battery will not be hot-swappable — like the BOBOVR M2 — there is something to be said about the elegance of the design. Kiwi claims it will be using a 6400mah battery from Ampirus that will add 4-5 hours to your current Quest 2’s approximate 3-hour play time.

If you don’t have the patience to wait, and you’re looking for a battery strap right this second, check out the Aubika Elite Strap. It has a 5000mah battery — which is still loads of extra playtime. It has great reviews on Amazon.
You can also grab the Aubika Battery with a case for a reasonable price if you’re looking to protect your Quest 2 on the go.
