an actuator on the battery compartment for adjusting the regulated pressure of air supplied from the outlet port; and

a switch on the battery compartment for turning the compressor unit on and off.

2. The portable air compressor of claim 1 , further comprising a plurality of elastomeric mounts coupling the compressor unit to the frame, such that during operation of the compressor unit, vibration from the compressor unit to the frame is inhibited.

3. The portable air compressor of claim 1 , further comprising a flexible compressed air line fluidly coupling the compressor unit to the air tank, the flexible compressed air line arranged between the compressor unit and the battery compartment.

4. The portable air compressor of claim 1 , wherein the opening is defined on a first wall of the battery compartment, the battery compartment having a second wall that is opposite the first wall and in facing relationship with the air tank.

5. The portable air compressor of claim 4 , wherein the outlet port is defined on a third wall that is in between the first and second walls.

6. The portable air compressor of claim 5 , wherein the tank gauge is arranged on a fourth wall of the battery compartment that is different from the first, second and third walls of the battery compartment.

7. The portable air compressor of claim 6 , wherein the actuator is arranged on the fourth wall of the battery compartment.

8. The portable air compressor of claim 7 , further comprising a pressure relief valve protruding from the third wall of the battery compartment.

9. The portable air compressor of claim 7 , wherein the switch is arranged on a fifth wall of the battery compartment that is between the first and fourth walls of the battery compartment.

10. The portable air compressor of claim 9 , further comprising a handle coupled to the air tank.

11. A portable air compressor comprising:

a frame;

a compressor unit coupled to the frame;

an air tank for storing compressed air generated by the compressor unit, the air tank coupled to the frame;
