how much power does this unit draw?
1832416
I found on the manufactures website it said, 1 kilowatt per 24 hours. That seems like an average and should be the best answer if you're trying to compute operating cost. If you're looking for load on your electrical system that is where I'd have to start guessing, but I couldn't imagine a situation where it was drawing even half a toasters worth of power. Not very scientific but maybe it still helps

Runs on standard 115V household current. I have two, and haven't noticed a difference in my monthly bill since I got them.

The unit has a UL label on the bottom that says 1500 watts. I doubt if it actually uses quite that much power. I don't have a clamp on amp meter and decline to build a rig to measure the voltage and current while it is in use. You could measure the amount of water, the temperature change and calculate the power required presuming perfect efficiency. All of that I decline to do as well. Sorry all I got is the 1500 watts.If you are worried about current draw on a given circuit I expect that this thing will draw around 12 to 13 amps. That is a guess not a professional opinion.

I think the question was... will this unit use 44 watts of power no matter the load? ie... will this unit still consume 44 wats if you only have a 5 watt load...My best guess is it will only use what it delivers to the load plus some wasted power in the 120 to 12 volt conversion process as there are no 100% efficient methods of conversion.

I have 5 of these units working off of 24v batteries (really 24-28v) and get near 300w each. I use to charge my Nissan Leaf which is 1500w.

It limits. I have a device that pulls to much and it just stays warm, while only drawing max of 6 watts from the wall. I calculated this at 1.17 amp, which is as advertised. Used it a couple days at max (waiting for the 3 amp unit to arrive) and it didn't crap out.

It uses standard 120v power. Wattage varies depending upon how high the setting is set to.

The unit draws about 11amps. You can't have anything else running on the circuit. Like a toaster oven, Microwave oven or the Refrigerator.

You should consider this machine to be load limited (full-time and NOT counting higher starting loads!) to around 1600 watts (figure about 15 amps). Without knowing the running/starting loads of each appliance (should be listed in the specs), it's not possible to give you a better answer. Good unit though, starts easily and runs quietly.

The current draw is rated at 60 amps for this unit. At 230 volts, that comes to 13800 watts. That's the peak. It will usually run much lower than that. Also, as an answer, why reply with "I don't know"?

According to the documentation on their website the no load power draw is less then 0.6A here is the link. http://www.xantrex.com/documents/Power-Inverters/PROwatt-SW/DS20101206_Prowatt_SW_600_1000_2000.pdf

It's rated at 2 Amps but only consumes 150 Watts of power so tha actual steady state draw is probably more like 1.25 Amps.

110ac. I'm not sure about the power draw. I haven't put a watt meter on it.

Hi,I just bought two of these and they work really great. Have installed them in my well house.Don't have any idea on how many watts they draw, but it can't be very high as the heat is not very high. My guess would be approx. 40-50 W.Hope this helps.George

Just barely. The sticker on it said the max amperage is 17.4 amps x 115 volts = 2001watts. I would go with a larger unit so you don't burn something out. I run with a 3500 and it does good but you have to be carfull not to run any other high power appliance with it.

It runs off a switching power supply 100/240 volts in, 13.5 volt out. Power supply is supplied with the unit.

This unit requires a power source. I would not purchase it. I have found better that would work for your application.

I am not an electrician so I am not sure I am answering your question, but here is what it says on the unit: "Output +5v, 2.5 amps, Level 3 efficiency level"
