"Gotta go fast" :-)

In my language we say it colloquially that way, turned out wrong in English. Should have been 5 Wh.

Rather you would say it draws 5 watts. If someone is interested in draw over a period, e.g. over one hour, you'd say it used 5Wh in that period.

Let's just cut through the confusion and say it draws (J/s)Hr / Hr. :P More seriously, if you are interested in energy the "correct" SI unit is J although in electrical applications [k/Mega/Giga]Whr is common. If you are interested in energy draw over a period, aka power, the "correct" and common unit is W. While 5 Wh per hour might seem simpler, it is equivalent to say this thing draws as much energy per hour as a device that that draws 5W would draw over one hour - needlessly redundant.
