USB-C - So this new spec says it will support 100w of power.

 

Then lets bring in the aftermarket companies that love to create cheap cables. 

 

How will we stem the actual fires that will ensue without actual enforcement of incorrectly constructed cables.

 

Is there any way to deal with this and the world of imported low quality or even US based junk cables?

 

I assume this will be a problem we will see - but I can hope not..

 

Does anyone know if insurance will cover a 2K laptop that catches your house on fire if you purchase a cable that does not meet spec and burns up?

 

Maybe I worry too much - We already deal with this in data cables, but they do not carry this much power. All I know is I really would like to see USB-C in just about everything.

I never want to see USB-C at all!  I'd much rather have separate ports for everything then have to  use an external break out box everytime to connect anything.  To answer your question, you home owner's insurance should cover the fire damage.

I don't think that fires would be an issue. If the wire was small enough, and the device was pulling enough amps to actually create enough heat to start a fire, then the voltage drop across the cable would be enormous, and therefore, the device wouldn't run.

 

Not to mention that the insulation usually melts before it catches on fire (I know this from experience). And if the insulation melts, then the wires short, and the host turns off power to that port to prevent overcurrent.

I HATE the one stop solution. It is just like wireless home routers, Your modem, switch, and access point all built into one box, no thanks. the more I see tech move in this direction the more I look for ways of making things modular. This is right up there with the conversation rased earlier about everything being glued together.

Well, at leas there's the stipulation as before that the cable or it's packaging can't bear the USB3 logo unless it actually meets the specs, so if it's got a logo you should be fine. UNLESS the mfr +/or seller are liars. Then you're on your own.

 

I'd trust Amazon Basics, Monoprice, and other widely-recognized discount brands, but I'm not ordering from some guy with an ebay store who ships them direct from China.

Simple solution. Instead of buying your cables based on lowest price, instead buy them from a reputable supplier.

For example, if you buy your usb cable from Amazon certified to work with a kindle fire, it is going to be able to handle 2.1 amps. Amazon has a vested interest in making sure of that.
