But this is important. Sort of.
I'm charging my Kindle right now. But I'm scared that it will die before our plane ride back (it usually lasts at least a month, but I usually don't use it as much as I'll probably use it on vacation, SO JUST IN CASE). I don't have a wall charger for it, but my cell phone charger's plug in has the adapter for a USB cord. Does that mean I can plug my Kindle's USB charger into the wall plug in thinger for my cell phone and plug it into the wall, or will it explode?

Everything the light touches is my kingdom.
