Interesting idea, I suspect it isn't possible with the existing connector. You either need to increase the voltage or the current.

The new 240W spec is 5A and 50V. Assuming 5A is the thermal limit of the connector and that can't change, to get 1500W you'd need 300V, which is probably higher than the connector can support in terms of conductor spacing.

300V DC is also quite dangerous, 48v/50v is already up there.

Maybe you can get there if the device doesn’t actually require a steady stream of 1500W. For example, induction stovetops often work with cycling their coils. Couple the idea of a charge pump, a whole bank of capacitors and Tesla’s trick of running cables over spec by constantly monitoring temperature and making on-the-fly adjustments, and you might get somewhere.

You may be able to run cables 50-100% over spec for a short time. But not 1000%. Thought experiment (don't try at home!): Take a random USB cable and short circuit a car battery. It will start burning within seconds.

50 V in the USB-C connector ?

What can go wrong ?

[minedwiz]

In power-over-ethernet setups, you can have up to 57VDC at the consuming device: https://en.wikipedia.org/wiki/Power_over_Ethernet#Standard_i...

50V is pretty much the limit that is still considered safe for humans to get in direct contact with.

Mmm yes 50 V over pins that are half a millimetre apart. I see no problem with this. No problem at all.
