    Hi iLegends! We would love to provide more information on the amount W needed on the device. Which you can use the Elite Strap we sale in our official store or official cable. You can find this information in our official Meta Quest website under specs! We hope this information was helpful. Please don't hesitate to reach out to us if you have further questions or concerns.

    I would be surpised if the quest 3 used anything above 9V because that is what their wall adapter has. Also, I think the highest amps you can get for 9V is 3A (27W), but that was from a quick google search. There is another thread floating around where someone measured the power draw of the headset under different conditions, and I don't recall it even getting to 27W. I'll add a link if I can find it.

    The battery that came with my bobovr m3 is actually a quest 2 battery and only delivers 5V at 2.6A (acording to the label on the back). I find that the quest 3 is at about 88% when the BOBOVR battery is depleted.

    The only battery I've tried that was actually able to charge the headset while playing was large ROMOSS Sense 8+ that has 9V/2A. The first time I used it (when I first got the headset), the USB connector got quite warm. Since then it hasn't, so I'm wondering if firmware changes may have changed things since I first started testing. Honestly, even the 5V/2.6A battery on the BOBOVR is good enough for me, and its magnetic and very easy to hot swap (although I personally only have 1 battery for it). Note I have seen posts about people saying their BOBOVR makes a buzzing noise. You may want to look into that. I have not experienced it.

    Can a 3rd party battery hurt the device? Who knows? That is a risk anyone who plugs in a 3rd party device has to take. I can tell you that I used 3rd party batteries for years on the quest 2, and have tried 5 different batteries on the quest 3. I can't tell you there is no risk, just that it is a risk that I personally chose to accept.

      The link you provided does not appear to contain the information you claimed it does. It does say that the included charger is 18W. That's not the question. Further into the Q&As there is a response that says

      Q: How many watts can this device charge at? Is it capable at charging faster than the 18w charger it comes with?

      A: We recommend sticking with the included 18w charging cable. The headset is specifically tested and rated for that cable, and it is the best option to reduce any potential issues that could arise using an unsupported cable."
       
      Again, that answer doesn't even pretend to answer the actual question directly. The actual question is important.
       
      My Quest 3, using the official link cable hooked up to my PC, appears to charge at 22 Watts by default and I think I've seen it go as high as 27W. We need the real answer to the question, please, not a shrug off onto the inadequate official statements already available, because the followup question is: given that capable PCs can and will by default charge it at higher than 18W, using only official hardware, is that safe? Exactly how high is safe? How should we address the problem as users if it's charging faster than what you declare to be "officially safe" (which, if the answer is "18W," is happening with a significant number of users, and thus needs to be addressed)? This is, again, just a reformation of the original, simple question that we're not getting answered here or in the link you posted, so I'll ask it one more time: what is the maximum charging wattage for the headset?

      Can we please get a simple, accurate answer, given the potential safety issue here? Personally I'd take a "yes 22W/27W is safe" or "no 22/27W is not safe," and I'd deal with my own situation from there, but this question clearly deserves a real, generally applicable answer, if only for everyone else's safety.

        I think the general consensus is that heat is bad when it comes to batteries, so in general I would personally conclude that you probably are hastening the decline of your battery by charging it more quickly and making it hotter. But I am not a scientist, just someone who uses google and draws conclusions...

        The real question I would ask myself is "what am I gaining by delivering 27W to the quest 3 over delivering 18W"? If I don't have a pratical need for it, why do it? The question of whether delivering more current will harm the quest 3 battery and by how much is really moot if I personally have no reason to deliver more current to it in the first place.
