I've got one.

OK ...

But it doesn't give maximum starting amps - only so called
maximum amps.

Yes, some of the cheaper ones (especially) are a bit vague that way.

And that figure doesn't relate to the amps my starter takes,
as that is less -

Ok.

yet it wouldn't spin the engine.

And was sold as a jump starter pack?

But I bought it as a power pack for other things, so not wasted.

But it came with jumper cable type crock clips etc?

He'd need a reasonably meaty one for the Rover. The other thing to check
is that the croc clips are making good contact. I had mine out for the
petrol topper the other day and nothing much happened, then I jiggled
the croc clips and away it went.
