And even if it isn't charged, you just need a standard micro USB cable, not anything proprietary. I can use the same cable (including the car charger!) for my phone and for my Kindle and for a number of other little peripheral devices.

That, and the only time I've ever had my Kindle go dead on me was when I accidentally left the WiFi on and used it constantly for like three weeks.
