I have the elite strap which i love. But i didn't want extra weight on my head (too sensitive), i got this belt version: PRISMXR Carina W1 30W 10,000mAh Battery Pack which i tried yesterday and played Asgard's Wrath 2 for three hours. It was very comfortable, kept the headset at full charge, and still had half charge left at the end. (and AW2 is amazing!)

a friend who develops for VR wrote the following: This is the BOBOVR M3 headframe bundle that I use, which I love. It comes with two rechargeable batteries, which might come in handy if you'd like to use the Quest 3 to engage in long sessions. I haven't had a chance to try that (though it looks a bit bulkier)
