Your cart is empty.The ECG-7MVR energy saving surge protector operates on a simple master/switched basis. If the TV or PC is on, then peripheral devices are powered on. If the TV or PC is switched off, then the peripheral devices are automatically switched off, thereby reducing power waste.

Using it to turn a home power amplifier on when I turn on my receiver/pre-amp. This amp has a hefty current draw. It comes right on as soon as I turn on my receiver and off when I shut the receiver off. No glitches, no unexpected shut offs, it just works like it should. We will see if it can handle the amp which draws up to 7 amps.

I have bought multiple of these extension cords and I definitely feel that have helped me save money on my electric bill, I have had no issues with powering anything I have plugged into these cords in the last year, would recommend!

I'm using this as a makeshift trigger/remote for a couple subwoofers in my living room. The subwoofers have an automatic mode, but the sensitivity is rather low, so they'd be constantly shutting off and kicking on when something heavier finally played. It was a poor experience.With this, my receiver is on the monitored outlet and the subwoofers are plugged into the dependent outlets. I was a little concerned that either the power usage of my receiver at idle would be too low to trigger the dependent outlets or standby power usage would keep it activated when off, but it worked perfectly out of the box without adjustment. Fortunately the subwoofers handle the power transition gracefully without any audible pops or noise. I thought this would be kind of a goofy solution, but it actually works perfectly.

3’ cord, not matching the product description saying 4’

When I first set it up with a computer plugged in to the control outlet, the other outlets did not come on (monitor and speakers). As I was about to return it, I noticed a small Phillips screw on the back with +/- markings. I turned it to the + side, but I saw no change. Then I turned it all the way to the opposite - side and the strip performed exactly as expected. If you experience issues with it, try adjusting that setting first. IMHO, this is dumb, but it is what it is.

I bought this product to allow me to turn on my computer, two monitors and audio amplifier all by just turning on the computer. The power strip works when the the computer is turned on but it turns off the monitors and amps after 6 or seven seconds. I measured the wattage that the computer draws and it is about 30 watts when the computer is first turned on and then oscillates between 7 and 35 watts as it boots. Apparently when the power strip sees the wattage drop below 10 watts it assumes the control circuit has been turned off and it shuts down the switched outlets. Adjusting the sensitivity pot did not correct the problem. Computer is a Beelink SER Ryzen 7

I was skeptical that this power strip would work so well for the price, since this is a feature I've found myself wanting in so many situations. ...Like turning on the vacuum when you start a power tool...Or turning on an amplifier when a preamp is turned on.Well this power strip does it at a really low price and while not feeling chintzy.

This device switches power on and off for devices plugged into the "AUTOMATICALY SWITCHED OUTLETS" based on how much power is being drawn through the "CONTROL OUTLET" while also providing a couple "ALWAYS ON OUTLETS" as a nice convenience. For my unit with it's sensitivity adjustment turned fully counterclockwise "-" I was able to switch devices on and off with a control load of about 7 Watts minimum and not less. The LED lamp illuminating my pictures, for instance, only uses 3 Watts so it would not be able to act as a master controlling device for anything being switched. Only devices that use 7 Watts or more can be used to control things. I found the limit by hooking up a tunable soldering iron and started turning the dial, finding that threshold. Below 7 Watts and it gets ignored, above and it can turn the switched devices on and off. (15W - 60W is the adjustable range in the specs) The trick is get that threshold solidly between the idle wattage of the control device and it's active wattage and you are golden. :-)Other users seem to have reported flashing on and off which would be very possible if the sensitivity adjustment wattage is close to the actual power of the controlling device while it is on and if the switched devices were using sufficient power to effect the voltage (and power) of all other devices in that circuit. Control device comes on....Switched devices come on and sag the voltage a bit...power through the control device dips (because of the voltage dips) below the switching threshold and the switched device is turned off. The voltage dip ends and the power going through the control port returns to normal, above the threshold and then the switched devices are turned back on again....over and over again. This "problem" (or amusement :-) ) should be manageable by adjusting that sensitivity control...why it's there in the first place :-)Smart Strip is the first (and only) manufacturer that I discovered to include a user accessible sensitivity adjustment to it's power-saver power strips. I plan to buy more as need arrives since the features and quality I need seem to be nicely present.
