While we are on the topic of charging....
An area of debate amongst the world of passionate Kindle owners is, Will the USB cable charge your Kindle?
I am firmly in the camp that believes no it will not. I have heard of two people who went on trips with only the USB, their Kindle, and laptop, thinking the USB would charge their Kindle, like it does for the iPhone. Within 24 hours in both cases the Kindle was dead as a doornail.
Some people have tried to convince me that the USB does, in fact, provide a trickle charge. They tell me that: 1) computer needs to be on; 2) Kindle needs to be off; and 3) it must be allowed to charge for 20 hours. (Do they really expect me to be Kindle-less for 20 hours? LOL). I actually haven't tried this scenario to see if it is true. I sort of wonder what does computer "on" mean? Are sleep mode or hibernate okay?
Moral of the story: if you go on a trip, take the charger. Do not rely on the USB! That would be my advice.
