150 watts. Says it in link. If 150 watts isn't enough buy one with larger capacity. Much cheaper then solar panels of similar wattage. Much easier and reliable as well.
Volts times AMPs equal Watts if we are talking D/C 12v dc times 20 amps dc equals 24 watts.
If your inverter people are talking 150 watts, that would take much more than the Lighter could carry.
The specs on the product are misleading, not very useful. Jim
You are using a inverter to change 12 to 14.8 volt d/c to 120 volt a/c, so you can use a battery charger to change it back to 12 to 14.8 volt d/c. Round and round we go.

K.I.S.S. keep it simple stupid.
Since you're going to be driving a lot that is what you should take advantage of. I assume you already have a battery tender or charger that you use at home right?
Why not get an inverter ? Something like this is cheap
https://www.amazon.com/gp/aw/d/B01KT26D ... s=inverter . Charge battery while your driving using inverter and battery tender.
I think that would be easiest and least expensive option.
If you do go solar at some point make sure panels are waterproof so you can leave them out even if it rains.
So as I mentioned above, these outlets are fused typically at 10 Amps (some trucks are higher). Chargers are quite inefficient - I would be surprised if they're better than 50% - and inverters are around 60%, so the net would be roughly 3 amps before popping a fuse. I think the OP is talking about a larger AGM, maybe up to 100 amps, where you would be able to put in 10 or even 20 amps while driving - that certainly can't happen through a cigarette socket with an inverter and charger.
For example, a BatteryTender+ says it input is 0.325 at 120 volts, or 39 watts to put out a charge of 1.25 amps at 14 volts or 17.5 watts, implies under 50% efficiency.

if you or anyone else has any learning disabilities let me know so I can accommodate you just ignore me.
Fixed that for you.
Again seriously you should seek some help, the stress you obviously experience isn't helping your health.

I guess what we really need to know then is what charger he has right and capacity of battery right? He has a ton of drive time so efficiency isn't necessarily an issue correct?

Fixed that for you.
Again I don't understand? That's not what I meant. It seems I'm not being clear and certain people can't understand what I am saying. If that's the case I want to actually help people.
Let me clarify. If anyone has a learning disability or medical condition which makes it difficult to understand things I say please private message me and I will genuinely take the time to help you.
For you palerider you may want to consider talking to someone about your anger issues.
Perhaps you should consider that it's YOU that is the problem. Same with your slinging accusations of "bully" at anybody that doesn't agree with you.
You're
projecting your deficiencies on others.
Take your own advice, and get help.

Your formula is correct but your math is wrong.

When did I say it was simplest lol? Direct current to direct current is obviously most efficient and simplest. Efficiency is not key in this specific situation. My suggestion is also simple and opens up more possibilities for powering other items.
Nice try though lol

Again I'm confused as to what you're getting at? Are you saying that using an inverter is not simple? Simplest was never part of this conversation until you used that term which I never claimed my idea was.
What is your suggestion for the original poster for his situation?

Oops, Duh, Multiplied sideways, forgot the zero
I play with volts and amps, not so many in watts, mostly low voltage d/c. Keep me honest!

Others have attempted to explain it to you. I certainly won't presume to believe I can get through to you where they can't.
