When you are parked you are using your parking or spring brakes. You don't need air pressure in your tanks until you want to move. When you push in your "brake release" button on your dash you apply air to over come the springs and release the brakes. If you loose air pressure (somewhere between 20 and 40# varies from unit to unit) your dash button will pop back out and set your spring/parking brake.
Most truck stops sell a 50' air hose with a tire chuck on one end and a trailer glad-hand on the other. Trucker lifts the air supply line to the trailer and hook the hose on to it. Then they can use the trucks compressor to air up a tire or operate some air tools. As long as your connection is properly installed in the system you will not hurt anything.
