Ecowatts, Airoption now PowerGard!


A Gizmo from the US that is said to save 10% Electricity

A gizmo that is supposed to store inductive fluctuations in mains current and feed it back into the system. They are claiming a 10% saving in power.

I have heard of such devices on a much larger scale for factories etc. I am doubtful of this type of device to say the least.

From PowerGard advertising:


The POWERGARD is new, innovative device that filters the supply voltage while improving the efficiency and power factor of the electricity consumed in a home by electrical appliances. It's purpose is to save wasted electricity in homes. You can use it 24 hours a day all year round without increasing electricity expenses.

(A bit of a strange statement given it is supposed to save you 10%)

The amount of energy that can be saved depends on factors such as the type of electrical appliances used (i.e. air conditioning, garbage disposal unit..), the amount of electrical used and even the location of the home. Homes near shops, restaurants and light industries, where voltage supply is unstable and may fluctuate, will see higher savings. In addition to extending the life span of appliance motors, the POWERGARD also reduces the reactive power generated by inductive loads. This helps utility companies by eliminating interference to the community power supply.

The POWERGARD is a next generation device has been professionally tested and checked for compliance with International Safety Standards.

How much can I expect to save per month by using the POWERGARD?

That depends on many factors; the size of your home, the amount of inductive motor load, and the amount you are paying per kilowatt-hour for electricity. It's not unusual for users of the product to see up to 10% and more in reduced consumption.

(notice it says "up-to 10%" - Like the signs in supermarkets which say from €1.99)


AFAIK it costs $200 dollars. If it saved 10% of energy bills it would be great. Realistically you might be lucky and get a 1 to 2% saving.
