DC-DC chargers have their place - anywhere the standard regulator/alternator cannot provide the correct voltage or needs extra protection from overload. Typically, this translates to anywhere the starter and camper/house batteries are very different chemistries. (Generally, flooded, sealed, and absorbed glass matt batteries all qualify as the same.)
But remember, the DC-DC charger cannot "make" current - it is still getting it from the vehicle's alternator. In fact, a DC-DC charger typically gives up amps to get volts.
These devices are just tools, not magic.
Lawyerly weasel words added because there are ALWAYS exceptions out there.
But really, this stuff is not hard to follow at the consumer level.

Very few LI chemistries are suitable.
LFP is the main one.

As I've come to learn, that can be a big deal.
Better to spend a little more for one that can, if one can.

Not sure if you are referring to the RENOGY dc to DC chargers. The one I have has DIP switches to set the setpoints.....
Yes, giving just a limited set of canned profiles to choose from, as is the norm.
I'm talking about **user custom** adjustment, so if I want my GEL bank to get 13.3V at Float but 14.2V for Absorb/CV
Or adjust my LFP Absorb up from 13.8 to 14.1V
like that. . .
