Been toying with the idea of getting one of these battery pack jumper
thingies like this one on the Bay of Fleas: http://tinyurl.com/hzczdkp

Any preferred brands? Does that one look like a good one? Are they
worthwhile or just a 'toy' that doesn't work particularly well?

They are incorrectly described as a 'starter'. If you tried to use it as
such the wires would melt.

I have one of these:

https://www.amazon.co.uk/DBPOWER-165.../dp/B00YDZR3ZI

and it has started a diesel 2.0l VW Touran with a dead battery (lights
on, no crank action left).

I was surprised... It seems to hold its charge well too.

I can't comment on any particular one, but my stepson, an ex VW master tech
and AA patrol, got one from eBay. When he saw it 'in the flesh' he didn't
think it would start a car, but when the battery on his Transit was failing,
it started that three times in one day, re-charging it after the second use.

He has subsequently used it on other cars, and unless the non-starting
vehicle's battery was completely dead (as in won't turn on the interior
light) then it has worked every time.

I have a couple of Floureon brand (not a typo) and they seem fine. The
"bricks" which also do USB and laptop power up to 19 volt use lithium
batteries. I would steer clear of the 12 volt only type with a handle,
these use (small, low quality) lead acid batteries, at least in the
cheaper versions.

My Floureons look virtually identical to this. My main thought on the
one you linked to was that it was at the bottom end of the price range,
but seemed to claim unreasonably high capacity. So personally, I would
go with something "branded", also Amazon's no quibble replacement of
anything faulty is better and easier than eBay's. Now I come to think
about it, one of mine suffered an obvious switch failure in the first
month (lost its positive "click"), but sorted easily by Amazon.

My 1.8 diesel Connect wouldnt start so borrowed my mates RoyPow charger and it started it no problem. So I bought one, nice and compact to store under seat.

Nope, havent tried enough to be able to say that.

Yep.

No, they do work very well indeed.

They all seem to lie about capacity. For example this one:
https://www.amazon.co.uk/DBPOWER-800...dp/B013UBRZUS/
is 8000mAh. They can't possibly have a DC-DC converter in there for
300A starting current, so the cells must be in series up to at least 12V.
That means you'd think it would be 12V x 8000mAh = 96Wh, but the seller says
lower down it's 30Wh.

8000mAh x 3.7V cell voltage = 29.6Wh so they're just adding up the capacity
of the lithium cells, which isn't how watts, amps and volts work.

Why not just buy the battery for $50?

Because, at post-Brexit prices, $50 is GBP40.49 (+VAT+import fee). The
Amazon pack is GBP29.99, and for that you get a charging circuit, battery
manager and leads as well.

I have bought floureon replacement battery packs for dyson mini hoovers
and they have worked just fine for the last two years.

Well, all I can say is I mentioned one earlier that has been
consistently good in my use and IIRC the reviews were excellent.

"Mixed reviews" on Amazon is a red flag to me - it usually means:

1) The manufacturing quality is inconsistent;

2) Some users do not really *use* the product to its claimed limits.

Agreed and that's why I just took a chance on an 18V 3Ah NiMH battery for my
Makita combi. I'd had it for a couple of weeks or so when there was an
e-mail from Ebay re. a review.
The battery charged well, has plenty of torque and has done some work, but
not enough to be equivalent to 1 of the original 1.4Ah NiCads, so I don't
yet know. When it's managed to go through a couple more recharges and use
I'll post back here on how it's doing.

Are you suggesting that you would disconnect the main vehicle battery, and
try to start and run from the jumper pack?

If so, I would strongly discourage that idea - it's not what these starter
packs are for, and could cause you all kinds of expensive pain.

If you want to test the pack's ability to start a car with a discharged
battery (which is what they are designed to do), then just leave the lights
on until the battery voltage is below the threshold for cranking.

Are you sure? Plenty of YouTube videos of folk doing precisely this with

a cold engine.

Until it starts and the alternator surges the voltage through the roof
without the damping effect of a lead battery.

Don't believe that one has 51 Amp-hours for a minute. But they do work,
you just have to follow the instructions. Some of us in uk.d-i-y

It probably is 51Ahr.
It will have a 3.7V 51Ahr battery in it probably at the 10hr rate.
That is not the same as a 51Ahr 12V car battery.

On reflection, you could be right. Of course the figure is only
meaningful if you state explicitly the voltage at which these amps are
delivered.

My similar sized Floureon T3 only claims 18 amp-hours (no voltage stated).
