I keep my Kindle charger plugged into the wall all the time, and just plug the end of the cable into my Kindle as required. The rest of the time the cable just lies around behind the night stand.

So, imagine my surprise when I pulled it out, blew the dust bunnies off of it, and... voila!

I didn't think that a five-volt 0.85A output could make that much heat.

What do you suppose happened here?
