    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.
