Does this receptacle draw any current when there is nothing plugged in? I'm wondering if it's electrically equivalent to a wall pad left plugged in.

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:

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 don't believe it does. It only delivers power when something is plugged into one of the ports.

Yes it does,nothing to worry about, just the current going through the unit.

It's 15 amps, so this will allow a device to pull pretty much the maximum current from a typical wall outlet. Anything requiring more current than this can handle shouldn't be plugged in to a typical wall outlet anyway.

Things that are plugged in still draw a low amount of electricity even if they are not turned on. PowerCenter prevents this from occurring by cutting power to idle appliances, devices.

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.

If I remember correctly, it just plugs in. I use it behind refrigerator and have had no problems. I will probably purchase another one for behind my large oak desk.

It is hardwired into your electrical system. If you are running wire up to code in the wall, it doesn't matter how far it is. Check with an electrician about the code. I have a thermostat mounted on the unit. Electrical runs into it. So when turned off, no power being drained.

I have noticed no jump in my power bill and it has been plugged in literally for a couple months now. To put your hand on the pad inside, I would compare it to a luke warm temperature, perfect kitty temperature but by no means a heat source to the room it is in. I am really happy with it.

Nope. It charges when it's plugged in, so you can unplug it and it works without a cord. It has an on/off switch to save power when you're not using it while it's not plugged in.

Im not really sure i just plugged it into my wall outlet but it don't take much electricity that i have noticed.

Karl, It doesn't use much power but I would recommend that you disconnect it when you're not using it. I've read statistics about the enormous amount of energy we use worldwide by not disconnecting the millions of devices like this. I use a power strip for my stereo, TV (it stays semi powered up if plugged in), and other devices. I just flip the strip off and everything connected to it gets shut down. The power strip may not be possible for you (or overkill) but I would disconnect when not in use.

Yes and No. The USB ports are powered and the surge suppress indicator works. I have mine plugged into a GFCI outlet. This device is designed to be attached to a standard duplex outlet using the supplied screw that mates with the screw hole for a standard wall plate. This cannot be done with a GFCI. I use it by being careful to hold the device when pulling cables out.

Plugs in to regular outlet. It was great last summer. Colded the entire back of our apartment. I hadn't expected it to work so good. Absolutely no complaints and believe me if there were a complaint I'd voice it because I'm a complainer.

it just plugs into the standard wall outlet. I works well. No problems with the unit at all.

Mine did. It just plugged into the wall. The unit is quite flimsy however. If I had it to do again, I would probably go a different direction.

I just leave the pad plugged in all the time. I don't think it consumes much power.

It does draw a lil current as long as you have 12v and about 3.2amps of current ur good i have it on a 5 amp fuse and it has never blown. It does use about 32 watts. now this is just what i have clamped it useing at run not fire up. Hope that helped
