Electric grooming device

An electric grooming appliance comprising:

• a housing;
• a hair cutting device supported by the housing and including at least one moveable blade configured to cut hair;
• an electric motor contained in the housing, wherein the electric motor is configured to drive the at least one moveable blade when the electric motor receives an amperage draw from a power supply;
• a sensor configured to detect the amperage draw of the electric motor from the power supply;
• and
• a controller contained in the housing and configured to receive information from the sensor, wherein the controller is configured to compare the amperage draw to a threshold amperage, wherein if the amperage draw is greater than the threshold amperage the controller is configured to adjust a power output of the power supply, and wherein the controller is configured to receive a plurality of samples of the amperage draw detected at a first sampling frequency by the sensor and determine at least one of an average amperage draw and a maximum amperage draw.
