Why is the "in-line" power saver superior to the "plug-in" type?
The "in-line" type of power saver or energy saving device is a power saver that allows an appliance like a refrigerator to be conected directly to an energy savings device. The power saver is then connected to an electric outlet effectively poisitioning it in between the appliance and the outlet. There is an advantage to this.
It maximizes the power savings of that particular appliance. It also protects the appliance against sudden changes in voltage thereby avoiding damage and may even lenghten the life of the appliance. An effective use of "in-line" power savers is for refigerators since this is normally used in a household 24 hours a day, 7 days a week. Another effective use is for air conditioners which is run about 8 to 12 hours a day in humid countries.

My own personal experience with this system is about 29% savings for my supposedly efficient refrigerator and 20% for my aircon (both with high EER compared with other brands). Other types of refrigerators, air conditioners or other appliances may have variable lowering of amperage. This is due to the different efficiency of design. This is why air conditioners with the same horespower have different EER (Energy Efficiency Ratio). The higher EER, the less effect of energy saving device.
