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.

Well, the issue is USB-PD:

- 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.
