I find that cigarette lighter outlets can barely even deliver 100 watts. It's such a poor quality connection, and that leads to significant resistance, and even at a 2-3 amps (24-36 watts) for extended periods (an hour or more), it can get pretty warm. And typically, cigarette lighter circuits are fuse protected at 120 or 180 watts, so drawing any more than that, if the outlet doesn't melt by then, the fuse would blow.

This all makes sense because these outlets were never designed with the intent of delivering power. They were designed to generate lots of heat to light cigarettes, and they are very good at that!
