The hair clipper includes a first and second fan that blows air over the motor to cool the motor so that the hair clipper does not get hot to the touch. The hair clipper also includes an ergonomically designed case that helps the barber or hair stylist hold, grip and easily maneuver the hair clipper. The hair clipper also includes a power cord with a power converter in the plug end of the power cord.
