That factor of 10 took me a minute. It assumes an inverter running at 100% efficiency. Since power in equals power out if the efficiency is 100%

12V.x 60A.= 120 V. X 6 A.

If you plan on using an inverter you might want to consider a generator.

Notice that the tv operating off 120v uses more than the 12v television. This probably due to the inefficient use of the inverter. Most tv's are 12v and use an adapter to plug into 120v. If you bypass the conversion of 12v to 120v back to 12 you use less energy.
