Framework 16 power supply, 65 watt? (sh.itjust.works)

Hi there, I've been wanting a framework for awhile now, just haven't pulled the trigger yet. I was perusing the website today, comparing the price and performance of different configurations, when I realized that the 16 needs a 100w power adapter, 180w if you've got the graphics card.

This is a dumb question, because obviously it would charge fine with the lid closed and idling or turned off. Or I could just upgrade my power adapters. But I have a lot of 65w USB C PD chargers in my house and cars, and I was wondering if anyone has tried using them, and if so how effective is it?

Like, 180w is a lot of power. If I'm just working on spreadsheets or something, I'm imagining it would charge just fine? Under a heavier load I would probably start to slip backwards? Where's the line? Movie watching? Light gaming?

Just food for discussion I guess, I still haven't pulled the trigger haha.

Thanks!

On Linux at least low enough power chargers will get rejected and won't do anything. Idk what the cutoff is but USB a phone chargers won't work.

Hmmm, well USB PD is pretty universal and I imagine that's what framework uses?

18w is pretty low, I agree and I wouldn't expect that to work. But the 13 inch framework uses a 65w power supply so it certainly seems in the realm of possibility. To me anyway.

I'd love to know if anyone has tried it

I can't talk about the Framework specifically, but my laptop will also reject lower power chargers (65W) when the battery is low, or the power draw is too high (i.e. when the laptop wants to draw more power than can be supplied).

Interesting, so perhaps it could be an issue. I'd be curious to find out!
