Try doing series connection.
The adapters aren't cheap.
Jackery isn't 5.5mm x 2.1 mm
Your right my Golabs is 5.5 x 2.1 ( I had to locate a SAE to 5.5x2.1 for my setup)
the Jackery is 8mm still an easy adapter to find

Is there a good forum or subreddit to learn about panels and applications people could recommend?

Yeah it's easy to get a bunch of money tied up in solar
I have been shopping for 100ah Lifepo4 battery's and to really get everything I would like
for off grid would be just under $4k

1200 watt panels (200x6)
600ah Lifepo4 battery (200x3)
Solar controller with Bluetooth
2000/3000w pure sign wave inverter
plus all the hardware, cables, ect

Still that's nothing compared to whole house solar from a contractor ($20k to 38k Embarrassment )

Not a forum, but lots of reviews and information: https://www.youtube.com/c/WillProwse

Outstanding! Thank you as I have been in the process of learning how to be more self sufficient.

How easy is it to use this for emergencies?

Can I just plug a power bank into it?
You need to get a charge controller, otherwise you seriously risk damaging things.

I have 5 similar quality 100w 12v panels. they work as they say they will.

that said, if i was getting into it now... unless i wanted a super small system that i know i wouldnt want to expand... i would get a higher V output panel. they are cheaper per watt. and now that the mppt charge controllers are so affordable, there is no advantage to low V panels. just a thought.

These are great panels, I have 3 of them in Mono and Poly. They both work great and are well made

These are labeled monocrystalline but photos sure appear to be polycrystalline panels. Google the differences and you will see these do not resemble monocrystalline cell panels. Maybe a website labeling error? Just a heads up if you are really wanting monocrystalline efficiency. Poly will take up more surface area as well for same wattage.
Same, was my first thought

Like those found on residential roofs [e.g. 60, 70 cells]?

not necessarily. like any solar panel that isnt 12v. renogy makes a 320w panel that is 24v. basically if you go up in voltage, the price/wat usually dropps. it also is great for line loss because a higher voltage means less line loss if you have a longer distance between the panel and the controller.

have the same question.
Not really. Hqst actually distributes decent panels,
Like renogy, but a 100 watt panel for a portable jackery? Nah, too difficult to move around. That's more like a panel you use with an RV. I use a 30 watt hqst, that's very portable to carry by hand.
