I have a 2000 WH portable power station that has a LiFePO4 battery. It is more than adequate for my needs. It has an AC input and a solar panel power input. How do I use a DC-DC charger to charge the battery?

Most likely you don't/can't, this has been covered on the forum plenty.
You'll likely end up adding wiring for an inverter installed in the van to mimic the "ac input you would normally use to fast charge" and plug your ac charger into that...
plenty of people around here have purchased large power stations and ask the same exact question.

Google "200wh power station" and the only option out there seems to be Bluetti AC200P 
And according to the manual it has all the adaptors to charge from cigarette lighter, or directly from a 12V battery. The current is limited to 8A. No DC-DC controller necessary

You have to to boost the voltage up to get those solar generators to accept more power because they're all limited to like 8-10 amps. I have an ecoflow delta 2 and figure it's not worth any effort to DC charge it because it'll only take 500 watts through DC but it'll take 1200 through AC. It's not worth getting a 12 to 48v boost converter to do a dc to dc charge unless you have another reason you want 48v power, and the only reason you'd want to boost to 48 is if you're running a starlink. IMO at that point you might as well wire up a whole standard battery setup.
I have no knowledge of this particular brand, but this is what you'd need to install to do dc to dc charging through a solar generator:

RV8R-this should be the US version. Not sure where the paperwork that I got is at and I am not sure how much I even received.

So @sands
These AIO units are easy ,,, just buy them & wire your van to them, but I am guessing now you see the biggest issue with them ,,, Charging them up from the Van.
The other biggest con in some of them is “they self consume” their battery power to the tune if 33% per day.
Much of the self consumption is the interior inverter or other electronics. It varies from AIO to AIO.
Then there is on many of these AIO the “repairability” of them. If something craps out after warranty can you repair it or is it bricked ?
We had a change in how we use our van, so I simply added a DC2DC charger ,, Problem solved. That is what you get with a DIY individual component system.
The last thing, is the efficiency factor. I charge with 12vdc & use 12vdc. With your AIO, you will PM Van 12vdc ~ 120vac ~ super charger to battery ~ 120vac or 12vdc ,,, 4 power or energy transformations.

Yes, it is a bit confusing but it seems there's just an ac input and a dc input, that can accept up to 48v from solar panels or some other dc source.
The manual is not too bad, I've seen worse.

I have a bluetti AC200P. I charge it exclusively from solar and it has worked perfectly for my style of travel. I don't regret buying the all in one system one bit. I would do it again. However, next time I would buy the bluettie ac200max as it has more charging inputs. I still may add the inverter to charge from the alternator at some point. But after a 6 week trip to AK and a 2 week trip to Maine and several rounds of living in the van while building a house it really has proven itself worthy. I even run a 12 volt electric blanket off of it for heat if needed.
I have 525 watts of solar on the roof. 3 175 watt panels wired in series I believe.

Has anyone used an ARK PAC to charge your batteries? If so how have you found it works? Google ArkPak 730 Portable Power Source | Ark Corp US
I don't need a lot of electricity but do need some. Thoughts? A van builder in my area used this for his last build.
