A small manner of nomenclature:

	The volt/amp is the ohm, by definition.
	The VA unit is the volt-amp or volt amp.
	(yes, its a small point, but quite real.)
	(it is convenient, but, perhaps, misleading to
	use the / for punctuation, since its also used
	to indicate division.  Usual engineering usage is
	voltamp, VA or V-A (also confusing, but no one
	would (hopefully) try to subtract.

	With luck and a good power factor.  cf adjacent post.

	Impossible to say from the info given.
	Might be 4400V at 1 A
	Might be 8800V at 0.5A.
	I gently suggest becoming a deal more familiar with
	the unit before powering it up.

	Also, what it puts out will depend on what the load is.
	The VA spec represents a maximum specified available
	output.
