E2 Energy Saver

I came across an interesting gadget at a Home Dec exhibition last month. The gadget in question is called E2 Saver. This gadget claims to be able to reduce your utility bill by 40%. You simply need to plug into any 13A 3-pin power outlet nearest to your distribution box.

The friendly salesman also highlighted that E2 Energy saver will
- Stabilise the flow of current into the building
- Improve power efficiency
- Reduce temperature of wire and risk of fire
- Prolong the lifespan of electrical appliances

Would love to hear from anyone who has actually purchased the E2 Saver and get some feedback/reviews in this product. It cost between RM300 to RM400 approximately and is available Handy Fix Sdn Bhd, Houz Depot Sdn Bhd, Ace Hardware Sdn Bhd, Home-Fix (M) Sdn Bhd.

The salesman also showed me a reduction in utility bills as a result of E2 Saver but that could be due to a variety of reason. I also googled E2 Saver Scam to see if anything came up from other websites or blogs. What I found was this product has been in the market for couple of years and has been getting mixed reviews from customers.

At one of the forums a user pointed out how E2 Saver works:
1. Inside all of these boxes are just industrial non polar capacitors. You can get it at electronics shop for ~RM5 each.
2. The capacitors will indeed filter out the noise in electrical current, and thus making your total power reduced. This is because:
Total Power = Real Power + Reactive Power
The cap reduces reactive power.
3. Old TNB meters (those with spinning discs, measures TOTAL POWER), so if your house is still using that type of meter, using the caps will help to reduce your bill to a certain point. (especially if you use a lot of aircons/washing machines)
4. The NEW DIGITAL TNB meters is already designed to measure REAL POWER ONLY. So, TNB does not charge you for any reactive power that you use anymore (true for houses only, but for factories, tnb still charge for reactive power under a certain level of Power Factor).

I am not sure if the above explanation is true and frankly i didn't know we had something called reactive power. Finally, E2 Saver does have a credible websites as more often than not these gadgets appear on website that look rather suspicious. I am rather skeptical about the whole gadget thats sounds too good to be true and you know what they say when things are too good to be true...
