if you read the product details you'll see pretty much no bank will claim it can charge the headset when in use, it will only decrease the rate it discharges
there are some cases where it can charge during use by doing what I said and not doing much with a quick charge capable bank hooked into it but I wouldn't rely on it
just ensure you always have your quest and bank fully charged before you decide to play and it'll last a pretty long time
