Is anyone positive that the outlet will not waste any electricity while no usb devices are plugged in?

The plug uses 50mW with no load. That's with absolutely nothing plugged in to it. So yes it does use some power but its a miniscule amount.

If the 50mW is accurate, that's roughly 0.0004 amps from your house wiring. So if you put 1200 of these outlets in your house and powered them all at the same time with nothing plugged in, together they would equal a single 60W light bulb.

I don't have a current clamp for my multimeter to measure it, nor the schematics of the device to assess whether or not it it would draw any current. If I lost any electrons then I would be positive!

1 milliwatt = 1.0 × 10-6 kilowattsmilliwatts will be represented as mW from here on out.kilowatts will be represented as kW from here on out.There are 24 hours in a day and his outlet uses 50mW in standby per hour.kW Perday(24 x 50) * mW = 0.0012 kW365 days per yearkW Peryear(365 x 24 x 50) * mW = 0.438 kWI pay 17 cents per kW17 cents * 0.438kW = 7.446 cents per yearSo it would cost me and additional 7.446 cents a year to have this outlet installed.

That would depend on your intended application for the device. Personally I found the "Belkin Conserve Socket with Energy Saving Outlet" better suited to my needs. (http://www.amazon.com/gp/product/B003P2UMQ2/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1)

No, the USB charger circuit never completely powers off, though it does reduce its power usage.The unit I tested (the "decor" style, which almost certainly uses the same electronics as this one) continued to draw a bit less than half a milliamp at 120VAC when nothing was plugged in to it. This is according to a digital multimeter that I wired in series with the hot lead to my house wiring. Note that it was neither a high-end multimeter nor an oscilloscope, so it should be considered a rough reading, but should still give you a general idea of what to expect in the way of power usage.

Not at all...mine is still working away - almost 24/7 with at least one to three plugged in. It doesn't even get hot. Good luck finding out what's wrong.

Yes, that's true. If you plug it into a surge protector it will not work properly, if at all.

On the contrary, I have had no problems with the USB device. It has worked better than my "4" outlet and has given me no trouble at all. I would recommend it to my best friends.

I've got them all over the house and I haven't found a USB device they won't charge yet. I can tell you they successfully charge various smartphones, wireless speakers as well as the larger iPad that requires 2 amp power bricks.On a side note, we had an electrician over for something unrelated and he loved them. He said it's the best USB wall plug he's used yet.

No, you need the USB. But if you have something that could connect the USB to a outlet you can go that.

I say "yes" by implication and design. Read the following review of the Accell: http://thewirecutter.com/reviews/best-travel-power-strip-with-usb/Neither the review nor the company website specifically state that the USB outlets are surge protected, so you have to draw your own conclusion OR contact Accell support.

I have left mine connected without being plugged in for a few hours without a problem. But I don't know about permanently I have never done that.

Nope, its just electronics. Zero issues, but you wouldn't be able to power it (requires two outlets)

I just plug it in houshold outlet, I have no problem, it works great, You have double check rating on the product

I have one plugged up into a multi-outlet surge protector and have not had an issue.

I'm not sure if I quite understand the nature of your question. But tell you what, I have it plugged in to my computer via a USB cord with other USB ' S plugged into it and ever since I bought it, it hasn't given me any problems. It was bought mainly for computers. There are no provisions made for outlets or sockets.

I'm pretty sure you get the benefits, just as long as it's plugged in to the outlet. It doesn't have to be turned on:)

I usually have it plugged in, but on a some 4 - 5 day trips, it's fine without recharging -- no loss of power/speed.

FWIW, I used it in Europe 2 weeks ago. Both USB ports died after 1 use. The outlets seemed to still function.
