Anyone know power consumption on the refine cutter?

Anyone know how many watts one of these cutters pulls on a 120v circuit?  Could it be run off of a power inverter from a car's 12 volt system?  Or would it need a generator?

Not sure of the watts these pull, but I have heard of a customer running one off of the vehicals 12 volt power inverter. Been a long time, but I do remember someone saying...

I will let you know for sure in a couple days

if my calculations are correct they are around 60 watts

Any feedback on this yet?  I'm looking to buy an inverter to run my 24" Refine and laptop.  I would like to know if the inverter worked and what kind of ratings it had.

Thanks

Joshlindt had it right.

Calculate as follows

Your cutter is running on 120 volts and the amps on my 721 is .5 amps or 500 milliamps.

So...

Formula Resistance ® = Voltage (E) / Current (I)

In Action Volts(E) (120)/ Amps(I) .5 = Resistance® 240 ohms

Formula Watts= Current Squared (I^2) * Resistance ®

In Action Amps(I)(.5)^2 * Resistance® 240 ohms = Watts 60

Woot for self taught electrical engineering!!!

(MIT offers most of their classes for FREE online for those who want to self teach / can't afford school otherwise. I love the project and I'm getting information that others are paying 6 figures for, though I don't get the pretty piece of paper at the end of it...)

Just to simplify for you a bit. Wattage can also be arrived at using the simple formula.

Watts = Volts x Amps .

So 120V x .5A = 60 Watt.
