Not for laptops or low power computers
on December 22, 2008
This seems like a terrific device to use when your controlling device draws a fairly steady amount of power, say, a desktop computer or a TV. However, it didn't work well for me and my low power computer. My computer is a Mac Mini G4, which is basically a laptop sans monitor, very low power usage. While using the computer, the power level drops so low that the device thinks it's off, and shuts down all the controlled outlets. I would expect that this would happen as well if you are using a laptop computer as the controlling device, as the laptop could start drawing power from the battery and nothing from the outlet.
The device does have a sensitivity switch, so you can set how sensitive it is to power drawn by the controlling device. This is a good thing, as many devices never really turn off completely, drawing a small amount of power to power a clock, for example. So, you do need a sensitivity switch so that you can set it to something higher than zero so that it will work properly with these devices. Unfortunately, even at the highest sensitivity setting, it is not sensitive enough for my computer.
