How long is the life of the unit if it were fully charged and left unused in the car boot for say 3 years ?

FULLY CHARGED USER LIFE SAYS 3 MONTHS IN MANUAL

What’s the difference between gt4000 and gt4000s or are they the same?

Dear customer, the GT4000S has no built-in pre-heating function while the GT4000 has.

My electric (EV) has a second 12v battery which starts the car, can i use this if it becomes flat?

THE ONLY PROVISO WOULD BE OVERVOLTAGE PROTECTION WHICH I AM SURE IT WILL HAVE , SO YES YOU COULD USE IT FOR THAT , YOUR CAR USER MANUAL SHOULD COVER THIS ISSUE.

I have a 12v tyre inflator and other 12v equipment. Is there a 12v output?

No but has a USB. I've got a USB to 12v female. Just plug your 12v into that.
