Never use ordinary household extension cords to elongate the power cable.
They may overheat. Always unwind cord reel extension winders fully before use.
Contact your Profoto dealer for proper equipment.
Due to the two stage SMPS (Switch Mode Power Supply) technology,
the Pro-8a could make a hearable sound during the recharge cycle. This
is fully normal and could be seen as the sign of power being charged into
the generator.
