I'm power/electricity dumb
I'm looking to buy an inverter that I would plug into the cigarette lighter adapter, that allows me to use certain electrical components while driving without using the generator.
I see tons of inverters and they are rated by watts. I'm trying to determine the right size I need to power the different items I have.
Now is when I get dumb. What's the right "math" that I need to analyze to understand the size inverter I need? Do I simply need to understand the amps a component continually uses? And if so, again...what's the right math that converts the amps used for 120v into a 12v/X watts inverter?
Does my question even make sense? Lol
