Need help - power pack advice

[HammerheadFistpunch]

Hey guys. Been a while. So I need help finding something. I've wanted a power pack like a goal zero for some time. Partly as a backup, partly because when I use the GX camping I would like to use it as a second battery system to run the fridge. When we tow the trailer the fridge stays in the GX and while the group 24 agm does okay, if we don't drive the car everyday it gets pretty deep into discharge. I would love to have something that I can use as a buffer, plus having something I can use to supplement the trailer power such as running AC without the generator, and if I get a solar panel, ideally use it to charge the house battery as well. So I am looking for a device but there are SO many and SO many crap models. Looking for some help if you've been out there looking. Must have

regulated DC output of at least 10 amps. Preferably with a cig or Anderson connection instead of a barrel plug
AC output of at least 250 watts.
Minimum 250 Wh capacity.
MUST be able to charge from both AC and DC 12V sources
MUST be able to charge and use its outputs simultaneously.
MUST not shutdown automatically
Built-in solar controller with universally accepted solar input (no proprietary crap)
Les than $500 for unit, solar panel and all charging cables required to work as described.

Would like

sine wave output
500 wh or more
USB-C PD 3.0

Lastly, It can't be crap. I don't want to spend a fortune, I don't mind buying off amazon...mostly...but it can't be a piece of junk.

Thoughts?

@hammerheadfistpunch I'm thinking you're going to need to build one. Off the rack with all that functionality would be a crapshoot.

So one of these, with your own batteries and solar controller? Just a thought, as I've been contemplating one of these as well with my own battery bank. (edit - not sine wave....booo)

Jackery 500 is $500 and does what you want.

@adamftw I was looking at those just now. I don't know if I trust that brand, but its caught my eye. The product and product marketing has a lot of "designed in America!*"

*but made very cheaply in China along with the same thing with 20 other brand names glued to it.

@hammerheadfistpunch all that shit is made in china, stuff like it is only as good as their warranty and customer service. this brand has good reviews all over the place.

[HammerheadFistpunch]

@adamftw good to know. Its on the top of my list so far

@thomas-donohue My trailer has something similar. It would be cool to have that built-in, but I need something portable. Though I have looked at doing this myself in various ways. The trick is charging.
