    Yes, maybe. But I just plug that 9 thing in PC socket and it can show wattage, peak wattage, power efficiency etc. And to test if its showing right, plug 40w light bulb in it or something similar.. I mean, of course maybe wattsup shows more precisely and can report back the consumption to the machine, to use it in scripts etc. But for random drain check the basic 9 thing is more than enough. Is in every supermarket.
