Again mate in commercial garage has li-on starter pack ,
size of a paperback , just shy of 200 quid, on his second
unit and third set of leads on warranty...

What I'd guessed.

The majority will be bought as a 'just in case' and perhaps even
as presents. So they might well be able to replace the few that
are actually used more than a couple of times under warranty.

Like most things, if it sounds too good to be true, it likely is.

I'd say a pair of jump leads are better value as a 'just in case'.

But you're ignoring the fact that these are sold as power banks
for charging any number of whatnots. You might struggle to
cover all their functions with just a pair of jump leads.

The OP only asked about their use for jump starting.

And the discussion had moved on to discussing them in general.

As regards other uses, I find a lead acid jump start
pack with built in tyre compressor very useful.

There is a lot to be said for doing that with Li-on instead now.

And does double up for the very rare
occasion I need a portable power supply.

So would a Li-on one which would do the car starting much better.

Can't really think of where a much smaller one would
be a killer reason to pay out that much more money for.

I can. When moving around without a car one of them
would be handy for keeping the smartphone charged
if you use it to listen to podcasts or read ebooks in the
sort of situation where mains power is hard to find.

Leaves you lead acid based one for dead portability wise.

Except for specialised stuff like model aircraft and so on.

Nothing specialised about smartphones anymore.
