How much harm from using Quest 3 while charging? The right charger and cable as possible solution?

TL:DR; How much will Quest 3 battery be impacted after how long, by charging the headset while it's being used, and could a laptop PD brick charger remove the battery strain? If the laptop PD charger removes the strain on headset's battery, how much more wattage than headset and charging dock requires is still fine?

 

Because it kinda sucks to needa wait 2 hours between each session, and since my old Quest 2 seems to be doing fine even after always having used a 15-20W phone charger connected to Elite strap with battery whilst using the headset (ofc only when battery got low), I've looked for possibilities to charge the Quest 3 headset too whilst using it (going for BOBOVR S3 Pro Super strap, while charging its power supply, but this post is about generally just charging the headset while using it).

I came across a post from DownunderGrumpy, where he talks about using a USB-C laptop power brick, as he says such chargers are designed for charging the battery and delivering power to the headset simultationsly, thus the battery stays happy as being charged while having to deliver power to headset strains it. The only issue however, is that one of the "quick answers" when searching for articles about charging the headset while using it, says to simple don't, as charging the headset while it's being used can eventually harm the battery.

And so, my question is how much the Quest 3's battery will be affected after how long when charging the headset while its under normal use or heavy load (ofc only once battery level gets low), for normal usage time a day, and if using a laptop PD charger compatible with other types of devices too would remove the strain on headset's battery? Another question in case the laptop charger does remove the battery strain; how much more wattage than the headset and charging dock requires is fine? Thinking of going for a Universal Notebook 65W PD brick power supply by Hama, or a simple 45W PD universal wall-charger also by Hama if 65W is too much, and it doesn't actually matter whether the charger form is like normal phone chargers, or like normal laptop chargers with transformer being its own part (brick form).

 

Looking forward for people's suggestions/answers!

Unfortunately, that article isn't what I'm looking for, as that knowledge is nearly common sense.

My concern is more whether a laptop/phone/universal charger from a 3rd party company could be compatible with the headset (like, if certain output volts and amps would make it compatible).

Just that I've read 2 threads by now that all say there's no issue with using such chargers, as long as they're designed for PD or something, and I'm personally planning to use the Quest 3 headset while charging it with the BOBOVR S3 Pro Super strap (B100 battery). The only issue is I'm not sure whether the headset will be harmed by the battery, since the battery's output volts and amps don't match what's listed in the headset's input specifications, or if the headset's battery will just be strained from it, and so if it could be harmed over time then how long it would take before the damage actually affects anything. Even if you can't find an answer to that question, I'd appreciate an answer to whether a 3rd party PD charger with matching volts and amps would be compatible and not cause harm.

It may only be of limited help to you, but I use a Quest 3 512gb with the official Elite Strap With Battery.

The ESWB is designed to limit charge to 70% when not attached to the headset or when being worn, (when not being worn, or being charged when turned off and connected to the headset, it'll charge to 100%).

From my understanding, the 3rd party batteries operate in the same way as a standard battery pack, which wouldn't have this safety feature as the official option uses custom firmware.

The headset will attempt to take the majority of the charge from an ESWB before the headset battery, however 3rd party batteries tend to operate in a kind of relay, (that is, the headset uses the battery, the strap is charging the battery, and the cable is charging the strap).

When turned off, an ESWB will charge the headset and periodically turn on to check for updates as the headset detects it as charging, the way to stop this is to unplug the cable after it's been turned off and before being turned in.

You may find it beneficial to contact Bobo support too.

Sorry for the longwinded response, and I hope it's not too confusing and at least answers some of your questions, (if you've not purchased the strap yet and aren't totally dismissive of the ESWB, it's something I'd recommend as an owner).

I've also added a picture of the ESWB attached to my Quest 3 512gb, should it be of use.

I could dream forever, and never stop. I could think of life and beauty, the stars that fade in the sky. The hearts of lovers, the dreams of dreamers.
