3. A method of electrostatic spraying with a portable fluid sprayer, the method comprising:
pumping a spray fluid with a moving fluid displacement member disposed within a sprayer body of the portable fluid sprayer, the portable fluid sprayer having a handle extending from the sprayer body, the fluid displacement member comprising a material that is electrically conductive, wherein pumping the spray fluid includes:
drawing the spray fluid from a reservoir disposed upstream of the fluid displacement member by the movement of the fluid displacement member; and
driving the spray fluid downstream from the fluid displacement member to a nozzle supported by the sprayer body by the movement of the fluid displacement member;
generating an electrostatic charge with an electrostatic module;
providing the electrostatic charge to the electrically conductive material of the fluid displacement member;
charging the spray fluid with the electrically conductive material of the fluid displacement member while the electrically conductive material of the fluid displacement member moves to pump the fluid; and
emitting electrostatically charged spray fluid from the nozzle of the portable fluid sprayer due to pressure from the movement of the fluid displacement member.
