My DGX Sparks are the first and only devices I have with 200W USB-C PD. Low power by AI workstation standards, but intolerable in a laptop.

Intolerable? Why?

Battery life

The comment I'm replying to appears to be talking about power DELIVERY, not consumption. Why would extra power-delivery capacity be intolerable?

The DGX Spark doesn't have a battery. If it comes with 200W delivery (actually 240W), it's because it plans on consuming close to that amount.

Although I'm kinda surprised the DGX Spark used USB-C at all for power instead of just like a DC jack or whatever. But whatever.

Thanks for the info. The use of the term "delivery" doesn't seem to make sense in this context, but OK.

Your lap cooking. They generate enough to noticeably heat a room.
