Title: QuickerTek iPad Charge Monitor

Check it (http://www.engadget.com/2010/05/12/quickertek-ipad-charge-monitor-tests-your-usb-ports-output-pote/).  It works with more than just iPads, and it seems pretty useful.  You can see if your Model M is going to tank your system.

See. That (http://www.engadget.com/2010/04/03/apple-ipad-charging-woes-usb-hubs-non-macs-and-weak-ports-not/)'s what happens when you don't use gold-plated USB connectors, Apple!

I have the USB toaster, too. Have you opened the box yet?

That's hilarious.  "Personal Debris Removal Systems."  Awesome.

Okay, USB power charging is the stupidest thing ever invented. If I'm not mistaken, the CPU has to cycle the voltage needed through itself and then to the USB port.

There are things called "outlets".

I strongly advise that nobody attempt to plug USB devices directly into wall outlets.

Yup, incredibly mistaken... Why on earth would the voltage need to go through the CPU?

I love USB charging. One little 1A wall wart, a resistor and a Female USB port, and 70% of my rechargeable products are good to go. I am also going the extra mile, and replace 2 of my single sockets with combined mains/USB sockets.

The CPU is like a pump that sends electricity around the motherboard, amirite?

Then again, the Greeks thought that the brain pumped around coolant for the heart or something like that.

Are you thinking of how the host questions the USB device to see how much power it needs, then decides whether or not to enable power?

Well, USB ports can power stuff when the system is off (in some cases anyway).

Whenever I plug in a USB device into most computers, they emit this weird high pitched ring. It's annoying. Only does it when the device is first plugged in.
