Ya that makes sense.
If you really want to know how much power it uses, all you need is a clamp meter and a line splitter.
I bought a
Fluke 334 and an
Extech 480172. You can also make a line splitter with an extension cord by cutting a slit in the cord, but I don't know if you'll get a true reading that way.
Really handy if you want to know how much power you're using. My clamp meter is overkill for the price. Any cheap one will do ya.
All you do is multiply the reading; Amps X Voltage.
Test your house's voltage where the unit is plugged in to get a true usage calculation.
