[TQ] New USB Specification Promises 100W Of Power. - Page 8

post #71 of 85
Anyway, I see the AWG 24 wire acting like a very long fuse if they use just 5v. They have to use 12v, and at least AWG 12 or AWG 14 wires to have little drop of voltage. It has to be short circuit protected and more.

Personally, I think we should use USB 3.0, and they should develop a standard that can use power from our computer to power directly our gadgets with 5V and 12V. A dedicate standard with a three-wire cable adequate for the amperage running through it. The three-pin connector should only fit one way into the device and into the case's front panel. And there should be splitters of that, so we can power our router, external DVD reader, etc...

I love the universal power/charging/data storage all from one USB Port, cannot wait for this to be real, seriously. Phones & Tablets that could be charged through USB would be awesome too, plug in phone to your desktop to charge it.

They are moving in the correct direction, great!

anyway, I think that it is pretty cool but some of that stuff is dumb, like a usb powered laptop? Why would you want a USB powered laptop? You have to have a computer to run another one, that is pretty dumb when you can just put it into the wall.

Some people just have better access to a USB port to charge something.

Like me. I live in a condo and although there are wall sockets everywhere, they're never where I need them, especially with the layout of the furniture and placement requirement of these furniture due to space constraint. The only way to get to them is to buy 12 feet extension cords that only seem to come in either bright ORANGE or white.

If it's an extra feature, why not? Never say dumb in an IT world. biggrin.gif

I am charging my Blackberry through a USB port right now and I can do the same thing with my n95, if it had a battery in lol

Your PSU uses 18AWG wires to carry up to 8A/+12V several feet with little heating up or voltage drop.

12 or 14 AWG is unnecessary.

Instead of having a USB port that carries 100W of power, why not just plug the darn thing into the wall?

I had read somewhere that USB3 was including a 12v wire in it in addition to the original 5v. Is this not the case? Is there only 5v in USB3? I thought one of the advantages of USB3 was supposed to be that external devices like HDDs that require 12v would be able to power off of the USB, rather than having a separate power source to supply the 12v. Perhaps I was mistaken and they were referring to USB4???
