> Power negotiation applies to USB-A Nope it doesn't.
Which is why there's more fires with usb-a

> Voltage can't go up arbitrarily, but voltage can safely be increased to ~48V or so in most applications. After 48V, humans start to get shocked / hurt, so that's probably the reasonable limit. Car batteries in ICE cars are nominally 12v. Grab both terminals and tell me it doesn't hurt.
When I was a kid, we had this massive high-voltage transformer that produced about 2,000 volts, at some sick amperage. We used it to make jacob's ladders. That was fun. Until I touched the two bars. I woke up on the other side of the room, smelling burning... me . That wasn't fun...

It should be impossible for any set of non-damaged, non-defective, spec-compliant set of USB-C cables and peripherals to cause fires. The specifications are very carefully designed to prevent any combination of cables and devices from causing damage.
> It should be impossible for any set of non-damaged, non-defective, spec-compliant set of USB-C cables and peripherals to cause fires. That is a fairly significant list of conditions. As an example, I have encountered significant heating in a damaged power cable on the original power supply of a laptop from a reputable vendor. It's easy to argue the owner should immediately replace the damaged power supply, yet many…
Why are comments here always so deliberately vague? I'd like to know which manufacturer. It seems like an important detail.

Then it's either not genuine Apple or it's not Thunderbolt. This is what an Apple Thunderbolt cable looks like: https://www.apple.com/shop/product/MD862LL/A/apple-thunderbo...
That's not a USB-C cable. The discussion is about USB-C cables capable of thunderbolt. Not the older, dedicated thunderbolt cables. Correct link: https://www.apple.com/shop/product/MQ4H2AM/A/thunderbolt-3-u...
What a mess…

For the record, the M1's GPU performance doesn't even start to compete with the 2021 laptop market, much less the 2014 one. GPUs have always been the biggest power draw in these laptops, and it's honestly no surprise that Apple can cut their power consumption down to 10w when their GPU is as pathetic as it is.
I don't think this is accurate. [0] and [1] have 3DMark Ice Storm Unlimited Graphics benchmark tested on both the M1 and the 4800U in the Lenovo Yoga Slim-7-14ARE and the M1's GPU stomps the Vega 8 R4000. It outscores even the Ryzen 5000 series iGPU. I've seen no evidence that the M1's GPU is anything but best in class for integrated graphics.

I have already enough talk with my family to explain which charger and cable goes to which phone. Even more humiliating is them looking at me as if I was complete idiot after me suggesting to them that the selection of cable itself may be cause of their problems. They had some physics at school and from their point of view the cable is just a bunch of copper and it should absolutely make no difference for how fast th…
> They had some physics at school and from their point of view the cable is just a bunch of copper and it should absolutely make no difference for how fast their phone charges. Even if it is just a bunch of copper, there is thin and long copper and thick and short copper. I had a cheap, long micro-USB cable that was too thin to deliver 2A at 5V, my phone couldn't charge correctly. Using the Ohm's law, I could calcula…
At least as long as the cable doesn't catch fire from the resulting power dissipation...
