Great little charger. I have three complaints: 1. It's the yellow color that makes it stand out in my car where it's plugged into the cigarette lighter. 2. It has a fan on the back, which means I don't have to put it upright on a car seat so I can see the charge level through the window. 3. The power cord is a bit short to reach the center armrest where I placed the Battery Tender charger (until I blew it up by starting the engine with the Battery Tender charger attached).
