Yeah, but what wire size is on the cigarette lighter outlet?
As an example a microwave can pull 1500 watts.
Amps = watts divided by volts. 1500/12=125 amps!
You will NEVER find a cigarette lighter outlet - anywhere - that will carry 125 amps.
You need a MINIMUM of 8 gauge wire, probably 6 gauge.
Look at the wire chart below.
And the other two images are good memory aids.
I use both in my electronics classes and my ham radio licensing classes.
The image of the Volts-Ohms-Amps is a parody of the old analogy of
volts=water pressure, amps is the water flow, and ohms is the
resistance caused by a too-small pipe.
To use the clock face look at the center section for your target value (like Watts).
There are three ways to get Watts - one is to multiply Volts times Amps.
A second is to multiply the resistance by the square of the current.
A third is to divide the square of the voltage by the resistance.
