1. A powered fastener driver comprising:
a housing defining a cylinder support portion, a drive unit support portion, and a handle portion that is spaced apart from the drive unit support portion, the handle portion defining a handle axis;
a cylinder within the cylinder support portion;
a piston movable within the cylinder from a top-dead-center (TDC) position to a driven or bottom-dead-center (BDC) position;
a driver blade attached to the piston for movement therewith along a driving axis from the TDC position toward the BDC position for driving a fastener into a workpiece;
a lifter engageable with the driver blade to move the piston and driver blade, in unison, from the BDC position toward the TDC position; and
a drive unit supported by the drive unit support portion and operably coupled to the lifter, the drive unit including a motor having an output shaft that extends along a motor axis, the motor being positioned below the handle portion,
wherein the handle axis and the motor axis intersect the driving axis.
