You're joking? It's all said in the thread.
I especially like the comment that devices DRAW power. It doesn't get PUSHED!!!
Not really, it is just quite confusing.
Is there an iPod that consumes 10watts? (If yes, i guess that answers my question haha)
Like stated before, Watts=Voltage*Amperage.
All gadgets that you can charge (having a battery) need a certain wattage. If you have a gadget that doesn't need the full 10W, it'll only draw whatever it needs.
Let's say you have an mp3 player (I don't know the wattage of my iPod) which needs 5W. If it has a voltage of 5V, then the amperage drawn is 1A (1A*5W=5W).
So, yes, I charge my iPod on the iPad charger (because the iPod didn't come with one), even though the charger for iPad has more W.
And drawing means the device will pull the amperage it needs. If it needs less than the charger can provide, then it just draws that. Usually, if you have a gadget that needs more, it'll pull whatever it gets and takes longer to charge.
The iPad needs too much for a regular non-powered usb-port. As it would take too long to charge, Apple supposedly has prevented the iPad from charging via such a port (that's what I've read).
I hope things got a little clearer.
