I'm not concerned about the running time but more about the potential

the lappy wants 4.62 amps there could be a problem.

Why it's just run at 3.5amps which it is rated at, unless it's a bit crap then there might be problems.
It will just charge a little slower I suppose.

Well not necessarily if the load it too great, it depends how the source
behaves. ie goes into constant current and drops the voltage, tries to
deliver the current and damages itself, or uses foldback current
limiting as many SMPSU do and turns itself off or right down until the
load impedance increases.
HOWEVER.....

I've subsequently found that the dell will only charge from a legit dell
power supply which has a chip in it that identifies the charger capacity
and the laptop alters the charging regime accordingly. No ID chip = no
charge delivered.
So the issue goes away!
The lappy itself draws around 20-30w according to how hard it is
working, display brightness etc.
