Re: Car Charger
+1, when buying a USB charger for devices like these, it's generally best to get the highest amperage output you can, for futureproofing reasons. You can use a 2.1a charger and plug anything into it and get a proper charge rate. My phone draws 1a, and it will draw 1a no matter if it's plugged into a 1a charger or a 2.1 charger. One thing to watch for, though, is often a charger rated for 2.1a can only put out that much, so if it has 2 ports, and you plug in the N7 and another device, something's not going to get charged at the full rate.

(This was actually a minor annoyance on a recent road trip - my phone's nav would stay fully lit when plugged in, but dim the screen when not charging. Once it was fully charged, it quit charging, and the screen dimmed, and I kept having to tap the screen to see what to do next.)
