Anyone got any experience with them, or can recommend one?
Only for a 1.3 petrol engine plus general use as a mobile supply.
I did see the video someone posted, in here from memory.
Amazing what it would start car engine wise given how small it was.
Not that much bigger than a fat pack of cigarettes from memory.
My guess is it will only work where the car battery is only slightly
too low to start the car. Willing to bet it wouldn't work with no car
battery in place, or totally flat. So rather like most jump start
packs.
You might be surprised. Okay, this clip is an ad but there are plenty
reviews of similar devices starting V8 engines with NO battery (other
than
the jump starter obviously).

Wonder how many cycles of this it would survive? Was the engine cold or
hot? How long is the warranty?
Be nice to hear from someone who owns one.
Those were my thoughts exactly, which is why I posted. However I ordered
one yesterday so I will let you know. Instructions typically say run for
no more than 4 seconds with 30 second recovery time to cool down.
Having seen these sorts of packs in use in model aircraft, where
flattening them in less than a minute at 60 times capacity in Ah
currents are delivered, Id say its entirely possible that a 10AH
battery, which is not much bigger than a pack of fags, is fully capable
of ONE start.,
Packs tend to last about 100 flights under that sort of abuse.
You want 3s 10,000 maH 30C or better pack
e.g this pack for under 20 quid, should be able to deliver 180A for a
minute..
