Abstract The utility model discloses an electric heater with a power self-adapting function. The electric heater comprises a switch power supply, a PTC (positive temperature coefficient) heating body, a PTC power detection circuit, a PWM (pulse-width modulation) controller and a direct current fan, a mains supply is electrically connected with the PWM controller and a power supply end of the direct current fan through the switch power supply, the PTC power detection circuit is used for detecting the heating power of the PTC heating body and feeding back the heating power to the PWM controller, and the PWM controller is used for controlling the rotation speed of the direct current fan according to the heating power and controlling connection and disconnection of the PTC heating body and the mains supply. The electric heater with the power self-adapting function can change the temperature of the ambient environment of the PTC heating body by adjusting the rotation speed of the direct current fan, so that the heating pow
