Abstract: The present disclosure concerns a portable deicing apparatus for spraying deicing fluid, comprising: a deicing fluid reservoir defining a component housing connected to the deicing fluid reservoir; a fluid dispensing device located inside the component housing and in fluid communication with the deicing fluid reservoir to propel the deicing fluid outwardly; a heating system having a heating unit in a heat exchange with deicing fluid in the deicing fluid reservoir; an energy supply assembly operatively connected to the heating unit; and a controller located inside the component housing and operatively connected to at least the fluid dispensing device and the heating system. The deicing fluid reservoir, the component housing, the fluid dispensing device, the heating system, the energy supply assembly, and the controller are displaceable as a single assembly. A method for transferring the portable deicing apparatus and a method for preliminarily warming deicing fluid are also provided.
