Thanks, I appreciate the intention/sentiment, but I do know how energy ratings and usage works. The porty doesn't have any stickers (pretty sure it's at least a decade old, and whatever adhesive was holding the sticks on had long since disintegrated by the time I got it)

Watts are also just the product of amps x volts. I've got a smart plug in one of my boxes that I could use to determine how many V/A it's pulling and then work out wattage based on that, but I don't think it really changes much. I'm gonna use it anyway on the days like today where the weather is a bit difficult, even if probably costs about $10-15/day to run (my assumption based on yesterday's cost and running time). The "bury your head in the sand and deal with the fallout later" approach, if you will
