I don’t know how I feel pumping 240 W through these flimsy wires. I know it’s probably alright, but still… it doesn’t look like it’s meant to take 40 amps.
I recently ordered several 240W PD USB-C cables and you should rest assured, they are chonkier
Thanks for the info!
I think if a device follows the standard, the 240 W mode should use 48 V * 5 A - still more than you'd use with normal USB cables, but less insane than 12 V * 20 A
I was guesstimating 40A × 5V. Your numbers sound reasonable!
If the cable is USB-IF certified you can trust it.
It's only 5 amps, not 40. Magic of increased voltage.
