How is that possible?
240 watts thru a USB C cable?
I routinely charge my laptop at about 60 watts (measured). I charge my power drill battery, etc...
All USB C.
As we know, the wires inside are 33 - 30 awg.

Surprise me!!!

All USB-C cables must be able to carry a minimum of 3 A current (at 5 V, for 15 W) but some can carry 5 A current (at 20 V, for 100 W).

(from Google) And, that would be minimum capability. Makes the "hand shake" when plugging in more complicated than 100mA or 500mA at 5V of "old" USB. More special ICs that (maybe) a hobyist can't find.

Cheers,

Well, I believe that it works!
I once had over 200 amps flowing through a length of #22 AWg. It worked well for about 0.0001 seconds!
Yes indeed, it did pass the 200 Amp benchmark!


You think you know a lot, then you learn more, and realize you knew nothing!

That reminds me of the old Amplifier Power Wars, and PMPO, where a 5W amp could be rated for 500W.

I wasn't familiar but found a good table on Wikipedia, it says quite a lot on this topic in the second half of the page.

Evidently there is a 240W configuration in Type C called USB 3.1, it is still 5A but requires 48V so would only be good for charging larger devices like laptops in that configuration. A charger (not labeled USB 3.1) with high power rating is more likely referring to the sum of all ports.
