Is it safe to use my electric outlet in my car for an electric pressure washer?

Most of the built-in automobile inverters I'm familiar with have a given maximum capacity rated at "100 watts". Why they rated them in watts , I don't know. This means you can use a 100 watt light bulb plugged into that connection. I've seen hair dryers, electric shavers, and computers plugged into these. I have seen some laptop computer draw too much current for charging from these auto 110v. outlet's too work. I don't have my charts handy at this moment but you, or someone, may can do the conversion from watts to amps for this. BUT, I'm dead sure you cannot use an electric pressure washer from your auto's 110v. electrical outlet. The motor on your pressure washer will draw too many amps for this. On the other hand-I have seen one situation where a customer bought a 5000 watt inverter and wondered why his battery kept going dead. The truck's charging system could not keep up with it's own electrical needs and his added load. My 2¢ worth, David
