Looking at get a holding tank from AliExpress. I was wondering if anyone has gotten one from them and if the DOT date code was current within that year ordered? Also are these a good tank to get. Here’s is the link to what I’m looking at.
Transfer/Holding PCP Tank Question for Newbie

I don't know the specific answers to your questions, but the label on the tank you linked to does not look like a DOT label, but maybe a CE label. If you plan to have it filled by an air source, and not fill it yourself, you most likely will have problems. If filling yourself you should have no issues.
Tanks with a DOT cert label typically sell for a premium over CE cert label tanks - even thought are almost certainly the same tank. Usually you'll see it called out as a DOT tank in the heading or description, and it will be priced higher accordingly. I don't see any such tanks in their store there, but you can see what I am referring to if you check out Acecare's line of tanks there: https://www.aliexpress.com/store/1101157152/search?SearchText=

It would take a lot of work to fill with one of those, as you'd have to keep stopping to let the pump rest and cool down. Those are not made for filling tanks, even smaller ones. Doing so might just kill it off pretty quickly. That said, if you wanted to fill it enough to shoot tethered, say to maybe 2500 psi so that you could just plug in your gun and shoot a lot, it might work out. But filling to 300 bar would be very tough.
The CS4 is made for filling tanks and can run for up to 5 hours continuously, so that would be a better option.
In truth, it does not matter how long it takes to fill a tank if the compressor is robust enough to do it on its own. I run with a 10 year old Shoebox Max and it is a slow but steady beast. I recently filled up a new 9L tank from empty with it, and it took it a little under 13 hours total, which I did over two days. But I just turned it on on a timer for ~4 hours at a time and it did its thing while I did other stuff. Now that it is full, top offs are much quicker. One of the efficiency metrics I calculate on my guns tunes is the number of pellets I can shoot for every minute of runtime of the Shoebox - most of them are in the 7-8 shot per minute range, so a full 500 count tin of pellets only takes about an hour of run time to fully replenish the tank. I find I run it about 45 minutes every week or so. I've got about 300 hours of run time on it and it shows no sign of slowing down. I believe slow and steady is the way to go with these - most of these low cost compressors run too fast for their own good . . . but the Shoebox (and apparently the CS4) are designed and sized to not cook themselves and can thus just do their thing on their own.
