FYI,

Charging via the wall adapter is faster because the current is higher through the wall charger. A USB port on a computer runs 0.5 A while the wall one runs 0.8 A (or possibly higher). The Kindle is designed to handle 0.8 A of current, so it works well (the voltage doesn't matter here). It does make a siginificant difference in the charging time. I find that via the wall charger, my K3 charges in less than 2 hours while it takes closer to 4 hours on my computer.
