Mix and match

I'm heading to southern California for a few days -- two days for work and two days chilling with my brother. I'm taking some of my photo gear down with me as I'm expecting to get out and shoot a bit with Pete.So here's the charger for my camera battery:The thing is I don't want to take down yet another power cord. I could use a 12V car plug, but that gets me in a worse spot that I can't charge without a car handy. (And don't get me started on taking a 12V power supply...)The 12V is a plain barrel plug and the mains AC seems familiar. Hmmm...Ah-hah!I'm already bringing the iPad charger... so there you go. A bit of tom-foolery later I have a wall-mount charger with no extra equipment!  :-D
