1. How does i-POWER save electrical energy?

When you turn on i-POWER, immediately it will improve Power Factor (Pf) of all your house hold devices. (To understand what is Power Factor you can read next Q&A, it will explain more concept, theory and technical side in more details). By doing so, your house hold devices has better Pf, hence lower starting power and more stable circuitry voltage and current is obtained. And it will then further enhance the Pf and reduce power consumption.

2. What is Power Factor Pf?

Our house supplied voltage is Alternating Current. (Unlike Direct current circuit, there is no alternating frequency, hence the Pf is 1 at all time.) So when we apply this alternating energy on loads (which mean your electrical devices), besides the existing “Measurable Resistance” there is another “Virtual Resistance” that will be created when that device has capacitive or coil like built in element. Technically, this virtual resistance will in return affect the supplied alternating voltage and current cannot coherence on the same phase through time. And Power which is the rate of work done by a device, is directly affected by Voltage x Current (V x I), So when you check both Voltage and Current curve at any 1 time, you will find they never overlap each other, so the Power Factor is always smaller than 1. Ideally, Pf should be 1 when the Voltage and Current are in the same phase thru time. so when Pf not = 1, from the equation, P = V x I x Pf / t, we need more power to achieve same work done needed for the same device. 

Virtual resistance is induced by all kind of coil and capacitors in the current house hold devices, we cannot measure them from a physical ohms meter, but we do observe energy lost when we use the device. And by using formulae from physics laws, we know they exist. Too bad, we cannot make our house electrical devices without capacitor or coil motors in them, so virtual resistance is everywhere in your house. This virtual resistance affect the phase shift of the voltage and current supplied, so the band curve of Voltage and Current can never coherence, hence Power Factor is always smaller than 1. Hence our electrical appliances will need more energy to get the same work done. As an example if Pf =0.7 then we need 1/0.7 =1.428 times (42.80% extra) of energy to produce same work for those device that has a Pf =1.

3. Since i-POWER can improve Pf , in term of energy saving, how much will it be?

We know that each electrical products companies have different marketing strategies including costing, design etc., so in will turn out same kind of products from different companies will have different Power Factor. For instance, Japan made and china made product will sure have different Pf. In Japan, 1 Watt of electrical power charge by Japan electrical company will be much more higher than same Watt charge in China due to its expensive living expenses. So Japanese maker will place a lot of weight in how to reduce power consumption when consider cost of producing an item compare to other Asian countries. So these products, customer pay more during purchase, but pay less later on electrical bill. But some countries, maker target is number of unit sales, so selling point become first priority. In addition, majority of the consumer are not technically told or trained on electrical field, so they dont understand much about power factory or pay more later, so they tend to choose cheaper products when they made decision on buying. Usually, they finally were offered low Power Factor products. But with i-POWER, even if you have very low Pf products, those built in chip and circuit in i-POWER can help to improve Pf to higher value, hence more efficient products and lower consumption on energy range from 10-30%.

4. So if i-POWER is really that good, why not electrical company install this product in everyone house?

I think you know the only income for an electrical company is electrical bill from us. So more power we use = more income for the company. So energy saving device in another hand is reducing income of a company, so it is against business benefit and no one will want to do that if he is working in that company.

5. Using i-POWER is it consider as cheating electrical company?

Since i-POWER is install in any of the electrical socket in your house, and not connected to the bill meter or before the meter, so that is no reason how it can affect the meter. You can install i-POWER in any socket in your house to do its job, or use an wire extension, connect it to any current electrical device in your house, it is just like another CD player or cooker you have just bought from the market. It will not affect the meter reading but only improve the power factor of your in house devices. So no way i-POWER can be claimed as cheating the meter or electrical company.

6. Is i-POWER the only device in the market saving house energy?

No, in most of the giant factories, they have big built in unit similar to our i-POWER which cost hundreds of thousands, or even million dollars to built, as they pay a lot of money on electrical bills, without said devices, the cost will be a bomb. And if they do not built that, electrical company will ask them to do so, if not too much lost of Power Factor will suffer the electrical company too. Today, using same idea, we minimize the design and make it portable and handy for house hold usage. And through MXB company we are really glad to have this opportunity to introduce this product to you.

7. How long can i-POWER last?

Japan Zeromax company give 1 year warranty to all i-POWER buyer. In fact i-POWER life-span is dependent on your in house current electrical circuit. If your current circuitry is stable (which mean the layout of wiring and all devices you use) then i-POWER will have very long life-span. If not it will be shorter. But Japan market has shown, minimum life-span on i-POWER on worst situation is at least 4-5 years, and easily more than 10 years if use in a right way.

8. Is there any restriction when using i-POWER? How can I assure all products in my house is taken care of after using i-POWER?

Just like our house circuitry, we have different fuses and control to separate our circuit to different supply to avoid overloading at the same time, when accident happen, it won’t paralyze everything at once. But since all circuitry will finally connected to 1 main meter for power reading, so I can safely say, basically our in house circuitry is all connected, But due to the nature of resistance and property of circuit, current will tend to flow to lower resistance circuit, so if you install an i-POWER too far away from designated device you need to improve Power Factor, it will not be so efficient. And when 1 circuitry breakdown, and happen i-POWER is on this circuit, it will then stop working until this circuitry is repaired. And once the circuitry is repaired and back to normal, i-POWER will start to work again immediately.

9. So how many units of i-POWER we need in order to maximize the energy saving performance?

Even though i-POWER can indirectly work on all circuitry in our house, but we know when the products get too far away from i-POWER, resistance will be created in between the product and i-POWER, so the efficiency drop dramatically. Also if you have too many products connected to 1 i-POWER, it will results in overloading the i-POWER which cannot regulate too many changes at 1 time, hence will reduce the results of i-POWER. It is better to use i-POWER near the devices you need. The best if you use 2 or 3 pcs, at far away corner of your house to obtain maximum results. Especially, in your kitchen as most of the electrical devices is highly power consumption.

10. How safe is it to use i-POWER?

To meet high quality and demanding criteria from our customers, we use flame-resistance material to built the i-POWER casing. And we have built in high-thermal cut off computer chip to turn off itself when i-POWER detects over loaded current flow or voltage raise. And only when voltage and current back to normal, it will then restore to its working condition later. So it is 100% save to use i-POWER, and with our triple (3x) QC inspection, all i-POWER is very safe before they arrive in your hand.
