Yesterday I bought one of these little 85W inverters. See here

When I got home I wondered if it would really work or would just overload the unit. How many watts to laptops typically use. The power adapter says 19.7 volts and 3.9 amps so i guess thats 76.83 watts which is pretty close to the max. Has anyone used these things successfully with their laptop?
