That model is likely overkill to charge ~50%...sounds like you really only need a small top up (20% or so) to get you back home under power:
This one would almost certainly get you what you need to get home under power:

I suspect this would get you 15-20% increase in charge over what you pulled in from your commute with.
if you wanted to go with one of the hefty jackery ones, this one would likely get you 60% from 0 or more charge into the battery of the rev (67k mah):

no need to spend 425 USD.
PS: this one is crazy cheap and would likely charge you to at least 60% from 0 (great reviews to boot) - at 64.8k mah slightly less mah than Jackery hefty one, but nearly identical spec wise, and much cheaper:

I may even give that a go for the price!
Source: I own this one and it charges my rev from 50% to about 95% (42k mah, while the two bigger guys above are around ~65k mah):

I can't recommend the one that I own...had some issues with it.
Thanks for the feedback.
I was thinking something more like this...
Amazon.com Portable Generator
I am no electrician, so I’m not super familiar with the conversions and such.
Seems to me priority one would be to put a functioning engine in there, not go buying solar stuff! :)
An old Blazer shouldn't be hard to work on, relatively speaking, so wild ass guess time, a thousand buck in labor time and then you need the engine; a used one isn't much. But since you can buy a new shitbox van from the 90s for similar money... maybe not worth it, unless you've really built that out and would rather not do that again.
The car battery will drain quite rapidly if it's not being charged by an alternator. And as soon as it hits less than 100% charge, it will start sulfating. The lower the charge, the worse the sulfation. Trying to use it as a power source without filling it up daily from an alternator (ie the running engine) will kill the battery in days or weeks (on the outside).
https://www.amazon.com/dp/B06ZXYVG4G or https://www.amazon.com/dp/B075SSMR6K or something like that would no doubt work to keep you powered. Take it to work and plug it in somewhere discreetly in the morning. There are smaller units that are a bit less. Lithium packs are very different from lead-acid starter batteries.
i use something like this

​
they have different capacities which drive the price , i also have the solar charger setup
Get something like this, or build one.

Possibly its big brother
This is the heater
Here's the solar panel I'm looking at.
