does this have zero current draw?

I haven't checked it on my bike, but it doesn't have a memory side, and it is required to be hooked direct to the battery , so I doubt it is zero draw unless you have it on the key side of the fuse block to kill it each time.....like I did. hope this helps

It draws no power engaged or disengaged. Small amount of power used to engage or disengage.

It requires a constant 12v but only draws current to run the timer, which is minimal. I don't guess I understand the question. I don't know how it could be hooked up without a constant power supply. The timer is hooked in-line between te battery and the item needing to be turned on and off. I use it to control a solar heater. It comes on and turns off at a predetermined time.

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. For comparison, I also measured a FastMac U-Socket, a competitor to this device. The U-Socket reading showed about 2/3 of the current that this one drew (with nothing connected to either device). I chose to keep this one because it is easier to fit into a gang box and seems to have a sturdier USB port design.

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

NO. this does not draw enough amperage. Hooked mine up with a 20A switch with a 10A fuse. Works great.

It draws very little current. I have driven 2 off usb power. If running from a micro controller such as an Arduino, you will need to connect to 4 I. O. Lines and 5v and gnd. Do a search on Google. There are plenty of tutorials on running it as well as some libraries that can be downloaded.

No. You would need a dummy load for that, something that would draw a lot of current without burning up.

No, you plug it in - Regular 110/120V No place for batteries - supposed to draw minimal power (equivalent to 30W light bulb??). Unit works great!

I do not believe so. . If the LEDs are totally off it should not draw any current .

Yes, unfortunately it does pull some power even when turned off. I thought it didn't but my friend the electrical engineer convinced me otherwise.

Yes, it draws 15 MA when connected. It is not necessary to disconnect unless you have a small battery.Best Regards,EH

that's what I am doing - here's what i am finding...the control item (using a kill-a-watt) is still drawing .005 amps when everything else is off...i know this is practically negligible and in the scheme of things it's not really gonna matter money wise, just led me to the question that if the most least power consumption device (i.e. -0-) was the control item there would be absolutely no draw whatsoever. Thank you for your replies and if I am completely off base, please let me know

Measured Draw at 13.2volts is 2.4 Amps, just purchased the product in December and connected to a Voltage/ Amp draw meter and there is no initial "strong" draw, just constant draw at 2.4 amps, this unit is running off a battery storage unit, charge by solar panels, for my fish pond in my Aquaponics System

my understanding is that the source side must be the most positive than the load side.also the measured current is only on the negative side (black wires).even with zero current the meter will still read zero provided you have at least 4v between the red and black load lines

I reviewed the spec sheet packaged w/the outlet and published on their site http://www.cooperindustries.com/content/dam/public/wiringdevices/products/documents/spec_sheets2/Combo-USB-TR-Recept-Spec-Sheet.pdf It does not specify any quiescent current draw. I would *assume any such current is negligible.

I am not sure what you are trying to determine. I don't have the test equipment to measure the small amount of power that this consumes. I did plug it into my Kill-A-Watt power monitor. The power consumed after 90 minutes still registered as zero. The instantaneous current and power were also zero. The device reads out to 2 decimal places so the power and current must me less than .00 amps and .00 watts. It is a very low power consuming device, exactly how low I am not sure. It is obviously not zero, just very low.
