Not a Taco Question but I bet someone can help...

If the charger you got has a usb c charging I’d recommend doing a high output charger with that. If it has dual charging, a fixed solar panel plus usb c would be a good combo. The 110 will be slow to charge.

I ran a wire from battery into cab to power an inverter then to a usb c. Combined this with a 50w panel. Both charge a little 200 watt generator that I keep in truck at all times.

 

****First your solar panels need to be parallel or series ready. Some solar panels are not & its a waste of your $$$$***

Here's my setup - Frig/Battery/Panels/Hardware

My frig has been on for over a year & its great for my beer!!
On my trips, the battery will last all day on an 8 hour road trip in hot ass summer -full freezer too. My trips back from the coast involve lots of seafood coming back in that freezer. You can plug it into your battery while you drive, but I just threw the frig in the bed of my truck & plugged it in while driving the truck. That battery can only take UP TO 80 watts input from solar panels - it won't charge any faster than that! In my living room, the frig & battery will last well over 30 hours on.

Check this guy out - He helped me a lot.

I think you may want to use a deep cycle battery instead of the stock battery.

Lithium Ion batteries are also worth a look.

 

To calculate the required amp hours (Ah) for a 12V refrigerator with a 60 watt draw for 12 hours, you can use the formula: Ah = (Watt-hours) / (Voltage).

First, calculate the total Watt-hours: 60 watts * 12 hours = 720 Watt-hours

Next, divide the total Watt-hours by the voltage: 720 Watt-hours / 12V = 60 Ah

So, you would need a minimum of 60 Ah capacity battery to run the refrigerator for 12 hours on battery.
