There is an element of truth, but what you're describing still sounds like a scam. Power factor correction is legitimate, but it's not something that can be done with a generic product that you hook up to any appliance, or even your whole house.

    The more relevant part is that as a regular consumer you don't need to do power factor correction because you don't get charged for reactive power. Industrial consumers on the other hand want to do power factor correction because they're paying for reactive power.
