I'm sure many people have done this, but I'll share my experience. I actually posted this in a different thread the other day. To make a long story short: I had a relatively cheap plug-in charger. Something shorted out inside of it and it got hot enough to melt shell, and I could smell it. I was lucky that nothing was plugged in to it, and that I was in the car when it happened. I used to leave them plugged in even when I wasn't in the car, but I can't trust them anymore. In all honestly I probably just got a defective unit, but it was enough to scare me away. YMMV
