Here's the confusing description on how it works: "Power Save Device improves the power factor by reducing the amount of electricity that is used from our utility company. This is accomplished by supplying electricity locally at the load by the use of specially designed capacitor. These advanced capacitor store the additional electricity needed for stabilizing electric current within an inductive load."
Reducing the amount of electricity from the utility company by storing it in a capacitor locally..
Now correct me if I am wrong, but wouldn't the capacitor charge from the electricity FROM the utility company in the first place? It's not pulling it out of thin air.

These things are usually a power factor correction device based on the "NASA Circuit", or so it was called in the 70s. They demonstrate it with an unloaded motor and it really seems to work well. When you get a well designed motor up into it's design load range those savings slip away. When Consumer Reports tested these things on a modern refrigerator it actually made it worse.

Aren't these similar to some device they used to market on TV that you could plug your 120V window A/C or refrigerator into and save money??? I can't find a link to that specific one, but I found a couple doozies
I've yet to have anyone approach me about hooking one of these up...
Is the Power-Save 1200™ easy to (install) We recommend installation by an electrician. The unit comes with complete installation instructions. It installs in about 20-30 minutes
