What's the minimal power adapter that will charge the laptop?

My question is about what the charging circuit needs to function. I assume the internal battery is either 7.2V or 10.8V nominal (2S or 3S LiPO) and a 20W charger typ only outputs 9V max so regardless of wattage it may not be a high enough voltage to charge the cells (even in 2S they need 8.4V if they’re std LiPO).

Ah. If I recall, the Framework-13 will actually charge from 5v! As long as it’s USB PD, it will charge while off. 5, 9, 12, 15, 20v. Some early units did have a bug with 15v, but other voltages still worked for those units.

@TvE

I’m also wondering whether PD is required or whether IQ works too. Why is this not simply listed in the specs? Or am I just not seeing it?

PD is required.
What’s IQ? I don’t really recognize it. Some Anker chargers have branding similar to IQ, I think. But’s that’s just a marketing term, not a standard.
