Bought a used air compressor to put in my box truck ( to change blades, air up tires, etc.) Works good & is small enough not to get in the way ( the same size as what trim guys use on new home construction). Just wondering if any of u guys use a different source of power for this set up. Of course I can run extension cords out to the house, but I know you can buy a plug for the cigarette lighter that converts to a 120 volt plug in. I'd like to use it out in the field if necessay without running cords out everywhere. Any ideas.??
