USB Type-C to Become More Secure with Authentication Standard

Seems like a response to reality to me. There’s a pretty obvious liability issue to these complex magic plugs that can deliver significant power.

It’s one of those things that makes USB-C really dumb. Any negligent Chinese manufacturer can drop a cable on Amazon that is a hazard.

In solving all problems, USB-C is a problem.

How is that any different from AC->USB adapters before USB-C?

My understanding is that different cables have different capabilities.

I find a wonky cable a higher risk than shitty charging equipment, especially as it may work fine for low power needs.

Before, power according to spec was 2.5 W, with common chargers going up to 10 W or so. USB-PD specifies up to 100 W.

Faulty usb chargers can put line voltage on the charging end anyway, regardless of the spec.

Or, Power over Ethernet. 48 volts at up to ~75 watts.
