The unit for $23.99 only provides reading for R12, R22, R502.
R12 and R22 were used in old-school ac for home and auto.
R502 is also older refrigerators.
Newer window unit use R410a
Present cars use R134a
As of 2021 and future cars will start using R123yf
So the point being most of those dials beside psi are useless unless you are still using old-school ac system.
Another point being with the new standard for auto Freon there will be more sales coming in near future. Make sure the unit you purchase, at least, shows R134a readings.

none of these look to have a charging port purge/burp point

You can use a gauge set check the pressure, but that does not tell you very much with R-410a. R-410a is a blended refrigerant with several components that have different vapor pressures, so you cannot tell the level of fill by measuring the high side/low side pressure, like you used to with R-22. R-410a systems are filled by fully evacuating them with a vacuum pump, then filling by weight, with the can oriented to fill with liquid refrigerant, instead of with gas phase like you used to do with R-22.
R-410a has moderately high global warming potential, and will be illegal to manufacture new air conditioners that use it soon. (Jan 1 2024.) The replacement is R-466a.

The manufacture of new R-12 Freon was banned back in 1996, but anything made before that date is still legal to sell, including both stockpiled new refrigerant, and stuff that is reclaimed from broken ACs and recycled. 25 years later, you can still buy R-12, but it's getting expensive - about 3 years ago, 30 lb of reclaimed R12 was around $600, now it's $1500.
A 25 lb bottle of R-410a is around $300. A mini-split generally uses 3-6 lbs of refrigerant depending on the size of the unit, and the length of the lines in the house.
You need an EPA 608 Type 1 certification number to buy bulk refrigerant, but you can do an online course for that pretty cheap. Technically, you may need to have a Type 2 certification to work on a mini-split if it contains more than 5lb of refrigerant, but I doubt anyone is checking. Here's a pretty good article on troubleshooting and refilling mini-splits...

the reason i went for it was because google said freon should be there forever. no need to refill unless theres something really wrong with the system. damn. cost me 5 grands just for listening to google.

Most units will start leaking at some point. There is no way around it. I would tell customers it isn't worth replacing the system unless it is over 10 years old. Under that it makes more sense to just top it off depending on how bad the leak it.
You can buy 410a on ebay. It's not crazy expensive today. Who knows what the future holds but higher prices. Buy today or pay more later.
You can also find it on facebook marketplace.

is it usual if it was filled 100% just last year and now its only 25% left?
