help needed reg a air compressor for a bot

 I am in need of a air pump/compressor which can produce abt 30 psi pressure (in a chamber not more than 150 cubic cm) in a relatively short time (say 20 seconds). I searched over the net for the same, my priorities are 

* small size

*low power consumption

*cost

[I have short listed campbell hausfeld rp1200 12v dc inflator]

(can any one suggest a better one if available)

 

Also,

how can i modify a device running by a car cigarette lighter into a 12v lead acid run device???

[ i mean, how can i get rid of the adapter and connect the device directly to the battery terminals]

if possible also give me details about the power and current ratings of the campbell hausfeld rp1200 12v dc inflator.

 

THANKING YOU IN ADVANCE.......

You can just cut the adaptor off, and solder/crimp some lugs that match your battery terminals onto the bare wire.

I couldn't find any power/current ratings for the compressor, but I found a reviewer that blew a couple of 10A fuses running it, and had to move up to a 15A fuse.
