Quote - "I always carry some conventional jump leads, as a belt and braces approach, so could if necessary extend the negative lead of the power bank using one of those."
If I buy a powerbank looks like i will need to consider buying a short jump lead set and graft on an extension from that to keep package compact.
Only looking at this because of battery tales on Forum and fact I will be leaving car for a few weeks over festive period in a northern airport car park. Would rather not be caught out!

The negative is only 10 cm long, the positive 20cm long. 10awg wire is rated at 30 amp continuous but can probably take a lot more amps for a few seconds before burning out.
These power banks make the claim they can start a conventional ICE engine with a starter motor. Thats a lot of amps. It would need to start in a couple of seconds I think or would burn out. It might only be possible if the main battery still has enough charge to supply most of the amps.
But I think I read somewhere that hybrids only need about 30 amps to power up their 12volt systems. And only needs this much because it needs to power a heavy duty switch to bring the HV battery into use. (which actually does the heavy lifting of starting the ICE. )
So for a mk4 Jazz the powerbank would never need to provide 200+ amps to crank the engine. Just 30 amps or so for a couple of seconds . I think it would work, although I have never needed to put it to the test. Has anyone on here ever used a small power bank to power up a mk4 with a flat 12v battery?
I'd be interested to hear the thoughts of experts.

« Last post by Lord Voltermore on Today at 08:19:00 AM »Good point. The universally recommended method of jump starting is to connect to a good earth/ground point , remote from the battery to minimise the chance of a spark igniting any explosive gases from the battery.
My little cheap and cheerful power bank comes with very short jump leads, spanning only about 30 cm (12") in total. Long enough to connect directly to the Jazz battery terminals ,(and most but possibly not all, larger batteries. ) Or alternatively the red lead to the battery and the black lead directly to a nearby bolt on the engine block . But either way all connections would be made very near the battery.
In my ignorant and reckless youth I often jump started directly to the battery terminals, and lived to tell the tale. And that was in the days of topping up cells.
Is there still a risk of explosive gases from a sealed ,maintenance free battery? Or is the recommended procedure just to be on the safe side for any type.
I always carry some conventional jump leads, as a belt and braces approach, so could if necessary extend the negative lead of the power bank using one of those.
