4 out of 5 eggs Good idea, but be careful of uses 08/11/2010

This review is from: TrickleStar 150PC-US-W PC TrickleSaver

Pros:

Does as it says, turns off devices when the PC is turned off. Is a lot cheaper than the controller outlet strip solutions I have found, but this only has one plug available! See Cons. Have had no problems with it after setting it up, seems reliable. I live where we use A/C about 6-7 months per year. With a 58W average phantom load that is off for about half the day and paying attention to the A/C effects, my payback time was ~ 9 months. I don't know how the other reviewer came up with no payback.

Cons:

- Only has one plug, so an outlet strip or other kind of break-out will be needed for running multiple loads. This adds to payback time if buying an outlet strip.

-The USB control appears to detect only the power lines on the USB port (probably to drive the relay direct). If the USB port does not power down, the TrickleSaver does not turn off. It would cost more to add intelligence into the unit to talk with the PC - and a driver would need to be written.

-The website could use some work. Download the PDFs to get an idea what they can and can't do.

Other Thoughts:

I'm a power electronics engineer, so I do these kind of calculations all of the time. Almost universally, people forget that the waste heat has to be removed by the air-conditioner, and adds about a 50% energy hit during the months that A/C is being used. My unit is controlling a speaker amplifier, scanner, USB hub, and a printer (I sometimes leave on by mistake). By using a Kill-A-Watt, I found I average about 58W added power with the PC on (not including the PC power).

They also make a power cord sensed unit that may do a better job than sensing USB power.

I would doubt that the unit opens the neutral (commented by other reviewer) as it would add another relay contact and raising costs. Anyway, it would have no effect on all UL listed appliances since UL requires that appliances not need neutral when off. Per UL, ground has to be maintained or double insulation used.
