1. A fastener driver comprising:
a housing including a handle having a trigger that is adjacent a grip of the handle;
a motor positioned within the housing;
an air compressor including a compressor cylinder and a compressor piston movable within the compressor cylinder in a reciprocating manner to compress air within the compressor cylinder;
a drive cylinder in selective fluid communication with the compressor cylinder;
a drive piston slidably disposed in the drive cylinder, the drive piston having a drive blade attached thereto; and
a drive train converting torque from the motor to a linear force applied to the compressor piston, causing the compressor piston to move in the reciprocating manner, the drive train including a drive shaft that is transverse to the drive cylinder,
wherein at least a portion of the drive train extends through the handle of the housing.
