I bought one of these from ThinkGeek: ThinkGeek :: Coffee Cup Power Inverter But I haven't used it yet. I see that the outlet on the Prius C has a 15 A fuse and they say not to use appliances that will draw more than 10 A (so 12 V at 10 W = 120 W). This device can deliver max 200 W continuous AC power (up to 400 W peak). So I guess this thing has the potential to blow a fuse. Am I probably okay as long as I don't draw too much power?
