Power Delivery, just another protocol like Quick Charge. It's not impossible that if your charger supports QC, it might not have the specific QC that Quest 2 has. There's a bunch of different versions, and protocols, out there for high wattage charging and not every device/port supports the same ones. It's stupid and you only notice how stupid the situation is when you get niche devices like Quest 2. Companies should be forced to list charging protocols supported by their devices like food packages are forced to have nutrition labels. But since it's only a niche problem few people notice, it won't get the attention needed.
