Could use a power-only cable? Or are they no longer a thing with usb-c and PD handshakes?

- reaperman 3y agoId imagine this would prevent charging using voltages over 5V?
- Kirby64 3y agoThe standard usb data pins are not used to negotiate the power profiles. The pins used for negotiating power profiles should be much safer, with fewer venues for exploit. Maybe not impossible in all cases, but it’s trivial to design a system that could not be exploited via the power negotiation pins.
