I wish my Xbox Series S would work on USB-C. Some guy modded his with a buck convertor[0] and I wish there was an easier way in 2026.
- 12 V × 5 A = 60 W
- 20 V × 5 A = 100 W
- 28 V × 5 A = 140 W
Meanwhile, that Xbox roughly needs 12 V at 7.5 A (let's say 90 W, but the internal supply is 165W) . So there is just no easy way to do it with USB-PD. Technically, you can make/buy some sort of USB-PD bench power supply to do this, but I'm unaware of anything on the market right now. One that I use (DPS-150) is limited to 5A output.
You're better off buying some chunky power bank (like Anker Solix) that has your regular wall plug outlets.
Doesn't help that many market their power adapters as such, but when you look deeper, it's something like 2x75W + 3x50W + 4x10W.
