Quest 2 runs off battery WHILE PLUGGED IN
-
@AWmk1 it does charge while on the USB 3.0 cable, just not enough to keep it a net positive. If you unplug it for Airlink or Quest2 games you will see the battery go down faster in my experience
I use an active charging cable that you plug in your USB-C wall wart cable into the USB 3.0 cable you have connected between the PC and Quest2. Even this let’s the battery get down to 78% or so before the next charging evens out. I haven’t experienced what the other user is reporting with his USB 3.0 actually holding a charge, probably my ports aren’t high enough wattage, but I’ve been using the cable for the last few updates:

@Snake122 thank you - that charger seems like a safer bet than the pcie card

To maintain a charge, you need a PCIE card that has additional SATA power at the board. Or something like a thunderbird card that offers more power than a standard USB bus.

This is what I have…works fine. And will charge past current state while playing. Or you can go with the corded option. All depends on what you want.

My LINK Cable (not Oculus branded, but cheaper KUJECT cable) charges fine. I also switched to a powered hub which slightly decreases the connection speed, but charges much better. Worked fine for over a year. Recently, I have been getting some random disconnects which I think might be due my Link Cable being a little flaky (rolled over it in the office chair one too many times, methinks!)
I switched to AIRLINK, BUT I keep the LINK CABLE plugged in. (I did have to drop my Bandwidth setting for AIRLINK TO WORK) I see pretty much NO DIFFERENCE in the quality or frame rate (DCS or BMS) and the cable still keeps my headset charged!
Of course if you are going to be tethered anyway, you might as well use the wired LINK, but my headset disconnection issues disappeared and everything works fine.
It is a Win Win situation (for me at least).
Just putting it out there…
P.S. Of course the cable doesn’t keep the headset 100% charged, but after a 2 hour VR session, it only drops to about 70-75% which is damn good! Especially with AIRLINK which sucks up a lot more juice. By contrast, using the Headset in standalone mode watching Netflix or something, after 2 hours it is down to 40-50% or less.

If you want to go semi wireless if you are getting good Airlink connection, I recommend one of of the much better than stock aftermarket halo headbands that then have a spot to attach your own battery charger or ones even built in. That’s what I do when I roomscale games too Airlink or native Quest games.

@Snake122 Actually I have this updated strap which DOES allow connection of a BatteryPack:

Just haven’t gotten around to purchasing a suitable battery.

@Rainmaker have you checked the link bandwidth with this pcie card? For me the quest now charges while linked, BUT it’s lower bandwidth than Link with my mobo bandwidth:
-
@Recluse What’d your Link bandwidth read while using the KUJECT USB vs plugged into the motherboard usb-c?
-
I own a Quest 2 and what I do is keep my Quest fully charged and have it plugged into a 20k mAH powerbank while using it.
If you keep it hooked up to a powerbank while its at full charge your Quest won’t get boiling hot from charging itself and you will have a battery life of atleast 8hrs (if your VR sessions are somehow longer than this…lol)
The obvious downside is that this is only viable if you use your Quest via Airlink.

This is what I’ve been doing - BOBOVR sells this very reasonable kit
It’s honestly a must have if you have lived with the stock headstrap, trust me it’s worth it.On top of which, purchasing the charging pad means that I can basically run the quest 2 for as long as I want, especially if i time myself and replace before the quest 2’s internal battery starts being drained. A single battery effectively doubles the 2.5 hours to 5 hours but with a second battery you can effectively keep going for as long as you want provided you replace the batteries before the headset dies.
Now, of course as mentioned you need to rely on Airlink or Virtual Desktop. If you end up looking into this, you can pick up a router for as little as 30-40 dollars referencing the BD guide found here
IF you use your quest 2 for literally anything else, this is very worth it.

@Rainmaker I tried this very same PCIE card and had horrible problems - audio while in VR was in and out, there was some stutter. Bandwidth was reduced by 1Ghz compared to the USB-C link on my motherboard. But true, this card DID provide a charge. Now I just need to return it and by a card that has more bandwidth I suppose.

Hmm. Interesting. That’s a bummer. Sucks you had issues with it. I haven’t had those problems with mine. A lot of hardware variables too though. I did have a heck of a time upgrading firmware on mine as my newer PC didn’t recognize it at all when I first installed. I ended up having to scrap an old system together on top of a desk to flash it. The dude that was trying to help me out from Vantec was pretty awesome though. Spent a few days emailing back and forth and he was doing what he could.

The Kuject charger is perfect - maintains/ builds a charge in my quest 2 as advertised, and I get the same USB bandwidth as the USB-C on the back of my motherboard. Even got 0.1 Gbps faster in this test. And the connection isn’t flimsy at the motherboard compared to the USB-C.
The performance HUD in the oculus debug tool shows no difference in Link connection speeds between the Kuject and the regular Oculus Link cable. -
Yep, agreed! The Kuject one I linked earlier seems to be one of the better in all the chaff of miscellaneous generic cables. It’s better than my first charging port cable like this.
-
My USB3 port is not enough to power my Q3. I use a special HDMI cable with additional power, that keeps it charged while flying. I can easily push 3h, perhaps 4.
-
Something that might help extend your play sessions is to reduce the screen brightness of the quest by a notch or two.
I did this by accident and prefer it for longer play sessions as my eyes don’t feel as knackered after a long session. Also reduces battery drain.
