The invention provides a power compensation method and device of a fuel heater and the fuel heater. The power compensation method of the fuel heater comprises the following steps: when the fuel heater is started and enters a heating mode, acquiring an internal power parameter value, an external voltage value and an external current value of the fuel heater in each sampling period; determining a first power compensation coefficient of the fuel heater according to the internal power parameter value; determining a second power compensation coefficient of the fuel heater according to the external voltage value; and according to at least one of the external voltage value, the external current value, the first power compensation coefficient and the second power compensation coefficient, compensating the internal power parameter value to obtain the compensated internal power parameter value, and outputting corresponding power. According to the invention, faults caused by underpressure or overpressure and the like of the fuel controller can be effectively reduced so that the operation efficiency, responsiveness and safety of the fuel heater are remarkably improved.
