DC to DC substitute?

How would you rapidly charge a wet cell battery between stops?
120v power port is in the truck bed and would like to avoid running a dedicated DC to DC charger this year.
Power requirements are 60ah rv marine battery. Main goal is to keep Dometic electric cooler and Maxx aor fan running for as long as possible in rhe summer.
Thoughts?

Are you asking how to charge a battery from 120v? The answer is a regular battery charger.
The rest of the time, the answer is a simple cheap voltage sensitive split-charge relay.
DCDC are only necessary for fancy batteries like LifePo etc., if you stick to lead acid you don't need fancy stuff.

Thats where im headed but the tongue box doesnt have a lot of space. For the solar charge controller dc to dc and more batteries. The m24 size box is all that comes with the intech flyer explore. Not alot of area for bus bars and stuff right now. Im trying to determine what power demands are then build a good system around solar panels and a LiFePO4.
Any ideas are appreciated

Remember that lithium has twice the effective capacity of lead acid since you can fully discharge it. So one 100Ah lithium has about the capacity of two 100Ah lead acids, and charges FAR faster.

There's a very good chance that the inverter that you have in your vehicle is absolute trash because it's modified sine wave and will not charge anything like a power station.

You could buy something like a NOCO Genius 10 battery charger and run it off your bed outlet. The most you’ll be able to charge this way is 10 amps but lead acid batteries can’t really take more than that anyway. So it won’t be fast.

Just buy a lifepo4 power station dude
