That sounds odd to me. USB3 is going to allow up to 900mA instead of USB2s 500mA, but I didn't think the voltage was being upped like that. In fact, according to Wikipedia, the minimum voltage is actually going down to 4v
http://en.wikipedia.org/wiki/Usb#USB_3.0 got a link to where it says 12 or 24V? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of maccrawj Sent: 31 December 2008 09:40 To: [email protected] Subject: [H] USB w/ 12V/24V power? Was casually looking into a single, multi-amp, 5V/12V power supply to eliminate all my wall-warts when I stumbled upon this, wondering if anyone had some insight into it? There's a newer USB plug/cable standard that supplies 12V or 24V along with data so you don't need power bricks for each external device? Reminds me of PoE for networking devices. Interesting idea, not exactly what I was looking for.
