Its the yellow one.
Im thinking of buying a double adapter for the 12v cigarette lighter type plug, and having one going from my mount to the power source, and another going from the power source to an inverter, such as this one

or this one

depending on what my laptop requires (electronics were never my forte')
Iv got a couple of questions for all you electronic wizards out there.
Firstly, will it work??
Which inverter would be most appropriate?
But mainly, will the 900 amp jump starter have enough juice to power a laptop and a mount all night??
If not, any other suggestions?
Any thoughts appreciated
Cheers

Matt, have you thought of just getting extra standard batteries for your lappy. I use a Toshiba Tecra, I have the original battery it came with (4 amp hr) + I also bought an additional 12 amp/hr battery.
When both are fully charged & I use the lappy on my pre-set observing settings, (everything set for maximum battery life) I get a good 6+ hrs of lappy use. The only issue I have is having to shutdown & re-boot when changing batteries.
I mainly use powered sites so it's not a big issue for me, but I'm thinking of getting another standby battery for near future unpowered site visits.
