I wonder what temperature this thing hits. I have an even smaller 65 W GAN charger[0] that gets pretty toasty under load. I can't really see Apple wanting to ship a toasty charger, though.

Hot but not too hot

60C is still more than enough to burn you. Just, not the instant you touch it.

Toastyness is regulated by law for anyone sticking to the law.

Many devices are made larger simply to have more surface area to spread the heat over to stay within the law.

Chargers that get to hot then thermal cut off (out of action for an hour) are so annoying.

I remember the old macbook pro chargers, they and the cable would get so hot it melted the insulation of the cable (over time). Not to mention the self-desoldering GPU’s inside the actual laptops.

I don't think it was heat melting the insulation, blame the TPE used reacting. Anyways thread from the last time Apple charger stuff was discussed: https://news.ycombinator.com/item?id=28054090

Ah thats interesting! The self desoldering gpu’s was also an issue with compliance, switching from leaded to lead free solder iirc.

I had 2 cables that melted like this. I eventually bought the newer version with a different insulator. Used with the same charger and same laptop, but no melting.

Wow, that's really small. Only 43 cm3 (without the plug) for the EU version. I own an a Anker Nano II 65W GaN Charger and that's already small with 64 cm3. I can imagine that Rolling Square one getting even hotter with that low amount of material, and thus cooling.
