If the connector is ripped out wouldn't it not charge at all?
Is it fixable relatively easily? I see the main impediment being the laptops are more 'sealed' and not supposed to be opened up unlike desktop pcs. I haven't tried with this one or looked so it may be possible. Not familiar with opening laptops, having been used to desktops.
I wonder if it might crack the plastic or something to open it. Not a great problem since it was a cheap device and don't mind bodging a patch over it after if I could get the charge functioning again as in this state it is very close to unusable.
Once open what would be the process of diagnosing and then fixing the issue? As earlier stated the wire and connector side seem fine, having checked again today, It seems the laptop connector side is the problem.
You will have to locate same connector on aliexpress and solder it in place. That's the only solution. :-//That is only “the only solution” if the jack itself is damaged, which we don’t know to be the case or not. If it’s just broken solder joints, then no new jack is needed. And if the PCB itself is damaged, then replacing the jack won’t fix the problem, either.
If you don't know how to diagnose broken solder joints/connectors, I suggest you go and find someone who can help you or mentor you - e.g. a local hackerspace/makerspace, repair cafe, etc. Trying to repair a laptop full of fragile components, glue, etc. as your first project is a good way to turn a simple repair into an unfixable disaster, esp. if you don't have the skills or equipment required.
A lot of (most?) laptop DC barrel jacks are not two-conductor, but are three: ground, V+, and 1-Wire communication.
“The latest” laptops? USB-C charging has been widespread for charging for over a decade now, actually. It’s only the most power-hungry models that couldn’t be powered by USB-C until the recent 240W upgrade to USB PD.

All the ones I have repaired were just + & - , using a "dumb" charger, so there was no communication, nor was there any provision for an extra contact on the barrel.
I have had a number of laptops, with the current one only a few years old, & they all used barrel jacks.
My son's & daughter's new laptops use USB "C".

I actually am not charging it with AC to DC via mains but I actually made my own connection direct to my van's leisure battery and it only uses +/-. It actually took me ages to figure out, with many suggestions to finally narrow it down to this one, that I had to use a voltage regulator to make it charge at a consistent 12v as my leisure battery fluctuates from 11-14

And you did not consider it necessary to mention that before? Hmpf.
Did you double-check by trying to charge the notebook via its standard wall-wart supply?
How much current can your voltage regulator provide? Replacement power supplies for that Jumper EZpad 6 Pro seem to offer 12V, 3A. If that's what you are comparing to, can your voltage regulator provide the same current?
Also, are you sure the voltage regulator still gives you 12V if the input from the van battery is below 12V (or just a tad above)? There are "buck/boost" converters which can do that, but many simple buck or linear converters cannot.
