this is the unit I got off Amazon , it pumps up in about 2 mins tops from zero. I would say its under 15lbs and its quiet . I set it up with a regulator so in the off season I can drop the air pressure to 45psi and blow the water system out and antifreeze charge the lines knowing its not diluted. I would say its 10" side 20" long and 16 tall. I check it at full pressure it ran at 14 amps peak (at 12 volts DC) so I made up a 8' long jumper cable set up with a clip on cables to make it portable (RV , truck or loan out) . I think its about 1.5 gallon tank also. after 10mins of running it wasn't really hot either.
