Can you use on stop start batteries

Check your manual, it is not advised for many stop/start vehicles!

It comes supplied with a double ended cigarette lighter plug to plug. How is that supposed to be used? To charge the car or the pack?

No ...it’s intended for use for any accessory you have such as a electric tyre inflator pump or an external light and can be used to charge your mobile phone when you’re away from the house and car ..and many other uses.

Can start 4lt petrol?

Yes - I’ve a 4.2 V8 petrol XK , never a problem ….unless you’ve a completely dead battery then leave unit connected for a few minutes before turning the key

Dimensions of the JS500 model by itself. I can only see package dimensions.

Approx dimensions Height 37cm Width 30.5cm Depth 12.5cm. Only minor drawback is that’s it’s quite heavy!
