USB PD 1.0 is irredenta in 2025. 2.0 is basically irrevent outside of old device still on sale.
If the charger does 60 watts or greater it’s going to be 20v. https://www.renesas.com/sites/default/files/media/images/normative-voltage-source-pdp-rating.png
Everything made in the past like 4 years is 3.0. Ideally you shouldn’t buy anything that isn’t PPS (programmable power supply) because it makes charging a LOT more efficient.
But good luck finding a 12v adapter, they’re very hit or miss on supporting it since 12v is optional now and not a lot of things support it.
And they suck trying to use them for an FPS.
