No battery-operated air pumps (35 to 50 psi) there?

I made my own potato gun, I attach a small battery air pump instead using a pneumatic pump each time. I have an air compressor, but is bulky and heavy to use constantly. I'm looking for a small battery operated air pump – not insignificant for aquariums.

The YES size and volume of the compressor, depends on how many cubic feet per minute CFM who needs that pressure? I hope this answers your question
