Volvo v70 diesel 2008 air compressor connecting question

[Suzi326]

My estate car has to drive over grotty tracks in the country and invariable the odd flat tyre. Now I have wasted my money buying the portable jump starters with a compressor included but they break. I have just bought a Ring 12 volt heavy duty air compresssor RAC900 but because my battery is in the boot and most times it's laden up is there some way I can connect it to a point in the engine to make the compressor work? Or do I send it back?
