I recently built a budget Power Tank/CO2 tank to air up my tires while out in the trail. I decided to compare how fast this new set up airs up my tires vs my Smittybilt 2781 air compressor. I know there's more way to set up the CO2 tank but this is the way I made mine work.https://youtu.be/SJ0pgVHh4yMhttps://youtu.be/SJ0pgVHh4yM
