Primitive connectors like USB-A and Micro USB are not offtopic, but may elicit a smug sense of superiority.

Magnetic cable just catched on fire while being tester under nominal load (www.youtube.com)

Let me know what you think, but this cable straight up melted and catched on fire after being put up to its nominal power.

It's weird, it says 100W on the connector and 240W on the chip that is digitally read via the tester. Someone really cheaped out.

Possibly a case of faulty chips that were supposed to be able to handle 240w, failed QA and got binned and slapped in a 100w cable thinking it's fine and users would just know.

Yeah that would be my guess as well.

But honestly who is pumping 240w through a magnetic connector in the first place?!? My MacBook Pro only has a 96w power supply. I mean are you charging a bike with that thing?

usb-c epr supports up to 240w. its still fairly limited on what devices will use that value, but for example, a framework 16 laptop with the 7700s dgpu option can easily pull 180w over usb-c.

no one has practically implemented magnetic cables with the new EPR standard yet though.

I'm really curious to see this!
