does the convertor run 5000w constantly or does it only draw the power it needs?

Hi Roy, the converter is rated for 5000W continuous. So, to answer your question if you plug in a device that requires 5000W then that is what the converter will draw for power. However, if you plug in a device that requires 1000W then the converter will draw 1000W of power.

It draws the power it needs it cannot run 5000w constantly if you need to run that wattage you need a higher rated converter.

Unfortunately I don't know and I can't test it either as our dryer is a regular US version. My Husband said that it depends how much capacity the dryer needs. He suspected that if it says 2500 W it might not work with 5000W transformer, also if you google it, you will find "recommend using a voltage converter / transformer which has a Wattage that is 2 to 3 times higher than your appliance. " http://www.220-electronics.com/voltage-converter-buying-guide.htmlSorry, that I could not help much with your question!

Correct. The TOTAL output current is limited to 2.1A max. That means you can draw 2.1A from one port only, if all other ports are not in use. Or you can draw 1A each from two ports, and so on. If you exceed the current limit (for example, 3A total), the converter will still run for a short while. But eventually it will overheat and burn out.

I have been using the power supply for a few months. The unit operates well. But it has problem with heat sinking. The unit has a finned heat exchanger to dissipate the heat but the power will cycle on / off because of the temperature rise due to inadequate natural heat convection. If you want the unit to operate all the time, you need an external fan to blow air on the finned exchanged. I hope this is helpful to you. Regards, Ram

I am not positive, but from what I have read it is so that you can draw twice as much power to supply the unit. most computer ports supply have a watt of power by using 2 you can suppy 1 watt. The unit is rated at 2 watts to supply that you will most likely have to run one usb port to your computer and the other to a powered USB hub that has a higher power rating. I have not noticed much difference with 500mv or a full 2000mv of power.

Yep...that is correct. It really doesn't draw any current under no-load. There are no noises, nothing...just the red LED lights for voltage or watts. I have used several different inverters and this one is my absolute favorite...it is a beast and built extremely well. No worries...it is a safe buy. Have had mine running continuously for about 7 months now.

That's what I've got it plugged into. Works great (for the power consumption - I only have a 300W supply)!

YES. It draws no power unless a device is attached. Cables only attached drew no power. I used a Kill A Watt to confirm. Hope this helps.

I have no clue. I have a 430W in mine and I don't have problems.. I can't see it taking that much.

Yes. Mine has been working for 4 months with no problems, but the power is necessary.

Don't know Paul. But ran about 50 watts (fan and light bulb) for 5 hours off the converter. Best, Ron S.

I can't comment on the power supply. I didn't have the unit on long enough to experience any power issues. I was so disappointed in its performance as a scale that I returned it and went with the GemPro 250.

I have it connected to 2 150W pannels. The Grid tie inverter has a little drop to it, so it always stays around peak. 250W. The way it works depends on your setup. Panels need the sunlight so when it receives 10v it starts up. It is pretty effecient. My setup iisa battery bank and and a transfer switch. When my bank is full I basically use that switch to transfer power to my gridtie. Its a small bank I have just for emergency power, so its constantly at peak voltage so my grid tie gets more use

Yes, the USB charging circuit in this outlet does use power even when nothing is plugged in. I tested by wiring a Mastech MS8264 digital multimeter in series with the hot lead that powers the outlet. With nothing plugged into the outlet, the multimeter read 0.42-0.44 milliamps at 120VAC. Note that this is not a true-RMS multimeter; the actual power draw was probably more like 0.66 milliamps. That's less than 1/10th of a watt, which might be so little that it doesn't matter to you, but it is definitely nonzero and does add up over time. My review contains some more details about power draw:

It draws 4 amps (48W) according to label. I have one and works great for us.

I purchased this and connected almost two full lengths of 5 Meter/600 led lights to it that were rated to pull 0.5A per meter, 2.5A per roll, so almost 5A total. Had no issues with it. I would check actual current draw, but it is installed at a customer's business. This is a substantial power brick - basically the same as a laptop has. I would suggest spending the extra couple bucks and going with this larger 60W power supply just to give yourself some headroom.

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
