The invention provides a power module and a charging device, the power module comprises a resistor unit and a power device, and the resistor unit is used for adjusting a driving voltage for driving the power device to be switched on or switched off. Wherein one end of the resistor unit is connected with the control end of the power device, the other end of the resistor unit is connected with one end of the power device, and the voltage value of the two ends of the resistor unit is driving voltage. The resistor unit comprises a temperature-sensitive resistor, the resistance value of the temperature-sensitive resistor is related to the temperature of the power device, and the driving voltage is positively related to the temperature. The reliability of driving the power device can be improved, the power device is prevented from being damaged, and then the service life of the power device is prolonged.
