Power Saver Max, Wattage-Zapping Device

oh great it may guide to many users of electricity because you had already use of it.

http://cadztech.blogspot.com

the salesman at the mall said that you need to plug the device closest to the appliance that uses the most power and is always on. i guess that means the refrigerator.

i don’t know if this is just sales talk but he also suggested to get at least two of these for homes that consume about 650 to 1000kwh.

Those are actually good results, considering you [I’m assuming here] have Christmas lights up during the Christmas season. Yeah, I suggest further trial and testing. Keep us posted. :)

i haven’t used one of these ‘power savers’ but the first thing that came to mind was the device was mainly a capacitor. sylv3rblade mentioned that it’s basically adding capacitance, and i think he’s correct.

in general, capacitance is added to the system to counteract the effect of inductive devices, i.e. refrigerators, air conditioners, large motors, transformers. by convention, a capacitor supplies ‘positive’ reactive power that would otherwise be supplied by the system (through Meralco). this supply of ‘positive’ reactive power generally lowers the current magnitude since it brings the power factor from negative to unity (1.00 pf).

if it’s truly a capacitor, precaution needs to be taken here – add too many of these ‘power savers’ and you risk having an overvoltage inside your house if you unplug/turn off your ref, aircon, etc. that is, if the ‘power saver’ does not have sensing of the power factor and doesn’t turn itself off automatically in the event of an oversupply. an oversupply of reactive power will bring the power factor to positive, and that will generally raise the voltage at your end.

in my opinion, it won’t matter where you plug the ‘power saver’ so long as you plug it after the electric meter.

also, Meralco’s residential billing structure and metering does not meter your consumption of reactive power (kVar) and reactive energy (kVarh). in commercial and industrial billing structures, kVar and kVarh is metered, and they are penalized if their power factor is below -0.80 or above ~1.00 and given a discount if it is in the region of -0.95 and 1.00.

however, i advice you to go ahead with testing, maybe there’s something else there that we don’t know of that would truly lower your consumption. like i’ve said, i haven’t used this device yet, and if it does what it promises to do, then i’m all for it :)

hi!
does it work?
i think since october… two months are up now… =)

please advise. thank you!

I bought that a couple of months ago and it seems that it didn’t really brought my electric bill down.

Halos ganun pa din.

If you open the device, it is actually a capacitor and some electronics to do the “knight rider” led driver.

we’ve been using this device for 2years now, there’s a significant decrease in kw/hr. We bought ours for 9k, that was 2 years ago.

i just bought mine couple of hours ago and i bought it on sale at 1,900 per unit plus a 10% discount. I decided to have 2 units for the actual size of our structure. It seems that the way these capacitors & resistors work is to reroute unusable “leak” electricity into usable, much stable electric current that would generate electric power for various appliances. Therefore, practically speaking, the 20-35% power savings we’re talking here is actually the electric losses naturally occuring through copper wires, hysteresis (electric motors) and other forms of ripple. And perhaps the most effective way of utilizing this device is to have it closest to your main switch as it would greatly bypass incoming electricity to other electric outlets.

I will be using these units starting tomorrow and observe the effects on my bills for the next few months. Any significant kW/H drops on my electric consumption, i’ll let you guys know.

I saw it on 20% discount sale this morning at Handyman. Does it really work? Any updates? Thanks.

Can you possibly give me the contact numbers or email address of the manufacturer of this POWER SAVER MAX??

THE HANDYMAN STORE cannot tell me whom to communicate, there is no contact details on the box or even inside ( the piece of paper ):

On the month prior to purchasing the POWER SAVER MAX, our consumption was 885 kwhs, with the Aircondition unit open overnight ( with an average
14 hours a day operation )., after I bought the
unit, we were able to use the Airconditioning Unit even in the hot afternoon. Our consumption nevertheless fell to 820 kwhs.

With the almost 24 hours operation, our Aircon Unit
suffered lost compression, being more than 14 years old. but still delivers some cooling.

A couple of factors, the POWER SAVER MAX, classes resumption, and other factors brought our current consumption to 400 kwhs.

i just bought this powersaver yesterday.. this morning it made a somewhat zapping sound, it goes on for a few seconds then the sound stops.. after a few minutes it made the same sound..

does your powersavers happen to made the same sound?

thanks..

I bought one.ill let u guys know if it does what it promises.

i bought mine 2mos ago at sm for only php 1500. when i open it its just a capacitor & some circuits for the blinking lights. am a bit disappointed because it’s just a simple device. anybody with a little knowledge in electronics could have done it but our monthly bill went down by 6kW so it’s a little bit effective but not as effective as advertised w/c is 20-35% savings. anybody got any idea what will happen if we 3 or more capacitors to the device?

the device is worth buying… i am using my aircondition unit 24 hrs 7 days a week. This is amazing. from 5000 a month now im only paying 1 peso… hahahhahaha

guys,
kiddin aside. i’m planning to buy one.
does it really work?
my monthly bill is ranging from php6000 to 7000.
i really need to know if it really work:)
thanks.

guys, the power saver max is really work, i already prove it.for my bill before P5,ooo it becomes 4k something…

i bought 1 yesterday. the salesman said that if your monthly electric bill is ranging from 5k and above(mine is 7k to 9k), you should use 2 to 3 devices. but of course, he IS a salesman. so updates will still be greatly appreciated.

For Aldrin : Thank you for explaining the running light (LED), which I always term as “Knight Rider”.

My unit has been serving its purpose since May this year, and it has so far paid for itself many
times over.

One tip I would like to share, count all your operating loads at the time you want to test the product, and then determine the KW load by adding the total wattages of the appliances running.

If the total load is 1000 watts or 1 kw., read the electric meter and read it after one hour, if the
difference between the 2 readings is one (1). Then you have an accurate electric meter, and your electric consumption is just right.

Reading from comments of users here,the power saver device can give significant savings if used for houses, offices, busines establishments with electric bills starting from 4000 pesos and up. I think it can also work for lower electric-usage houses,those ranging from 3000 – 2000 pesos or below but the amount saved will only be minimal.

Well any savings by any device whether in hundreds or even a few pesos is a better alternative than being charged monthly with transmission and system losses which apparently also include, aside from illegal connections, Meralco’s and their payment branches’ electric usage in a given electric grid.

is this really works? i bought it yesterday in handyman the sales girl have a geat tounge to let the customer purchsd it

i also bought 2 units during a supposed sale in trinoma which costs P1500 from P3,900(which i just found out that it really cost P1,500 only. the fact that they are saying it was on sale was very misleading and therefore the electrical savings they advertise might also be misleading. i’ll find out in the my next month’s bill.

pls compare same month on different years…

my friend has been using 2 units of power saver on their home… their usual electrical bill is around 10kphp on the first month of usage it turn 9,800php. but this month which the 3rd month that they have been using it their bills turn out to be 8,700php.

not bad…

im still wondering if they could still add another unit to still lessen the bill…

As I was reading all comments, our water tank got filled and overflowed. It dawned on me that this is the same as the claim of the Power Saving Devices. The water tank is like the Capacitor, and at peak hours where electricity source is less, it supplies (partly) what’s needed. However that electricity stored has already passed the electric meter and we are all billed by KWh used not on amperes or voltage. In short, if all the drop of whatever happened after the meter, there is no savings.

Hi all,
I am running an experiment on each area/appliances in the house by using a power meter (that measures actual kwh) instead of a clamp meter (that measures current). I will post my results here next month. My mother-in-law has 2 of these power savers and I will borrow one from her for my experiment.

Yesterday, I bought two units of Power Saver Max at Landmark, Makati for P1,796 each. I’ve scanned the front and back of its package (See link below). I just wonder if this is really effective in helping bring down our monthly Meralco bill. Please, anybody who have also bought this device to post your review. Thanks.

Hi! I”m quiet at a loss on where to plug the Power Saver Max (PSM), since it is indicated at the “box” of the unit, to “Simply plug it on any AC outlet”. Inside the box however, there is another instruction that goes like this: “Do not plug the PSM beside the plugs of high electricity consuming appliances…”. In my case, I just plugged it at the almost “end” outlet in my house. Will PSM perform its desired effect of reducing my electric consumption? Please satisfy my curiosity. Thanks a lot!

Initial results:

This is a follow up to my post on Mar 19. I borrowed the Power Saver Max from my mother-in-law and plugged it near the refrigerator.

For 2 data points (24 hours usage). The Power Saver Max (PSM) has lowered the power consumption by about 20%. I also measured it on an aircon and got 11% power savings. Now this is just 1 datapoint for each appliance. I am planning to buy 1 PSM and will get more data to check for consistency.

will power saver be effective say on internet shops with 15 cpus?

@Luckster – What kwh meter are you using and how is it set up? (i.e. how is it wired into your circuit) The reason I ask is because it should be able to take into account the phase difference between voltage and current. It is absolutely important that the instantaneous voltage and instantaneous current are taken at any given time and integrated over time, and not just the RMS values. Otherwise, power factor should be considered as well.

The power meter that Meralco uses make use of two coils (one for voltage, another for current). The voltage phase is shifted by 90 degrees using a lag coil. It is this phase difference that produces eddy currents and make the aluminum disk to rotate. In a purely resistive circuit (incandescent, flat iron, etc), the phase difference in the meter is 90 degrees. In a resistive-inductive circuit (aircon, ref, flourescent, etc), the phase difference in the kwh meter would be less than 90. For the same power measured by the kwh meter, the current in the inductive load would be higher than the purely resistive load, or a circuit pf corrected by capacitors.

@Emer
The link below will show you a similar wattmeter I used. Basically I measured the kwh consumed with and without the PSM (power saver device) using the same parameters (time elapsed, thermostat value, time measured). This watt meter takes into account the PF (power factor) thus both inductive and purely resistive loads are measured almost accurately.

@Luckster
Kill-a-watt meter…Now this is some product that everyone should have. First, it makes us aware which products consumes most. Second it makes us aware more about saving. Third, it helps us verify the power saving measures we are doing. Thanks! Is this available locally?

For the Electrical Engineers here, has anyone made calculations whether I^2R losses in motors significant enough to be affected by less than unity power factors? Because in any case, this is the only savings the Power Saver Max can provide that I can think of.

I saw this gadget at sm north. so i decided to listen to his explanation. for some time a crowd starts to build up. Just for fun, i interrupted him and did calculations from his measured amperes. After the calculations the power saver has no effect and they were shocked by the numbers done in front of them.

The price and product is a rip off. this also do not apply to those who are billed for real power.

@Emer
just what all of us thought. it is just a big damn capacitor.

this kind of power saver doesn’t satisfies the theory of power factor..lets say right!!!!you need a capacitor to bring back the power factor to unity…but??????for only one load lng un…means one capacitive reactance per inductive reatance for equilibrium state…so ung nbibili ay isang capacitor lng ang laman..oo kapag kinbitan mo xa ng lights or washing machine motor..yap mkikitang the current consumptions will drop down..but???bkit unti unti ng nawawalan ng effect ung power saver kapag ntaas ung load???kxe di n nya kayang tapatan ung inductive reactance nung iba pang load..un b ang kind ng power saving device???tsaka bkit ameter lng ang patunay nila sa product nla????dapat my power factor meter din sila para mlamn ntin kung talagang it really corrects the power factor in any kind of loads n ikakabit>>>>kxe to prove that power consumption in VA should drop down..dapat mkita ntin n ung power factor ay laging unity or .99 so that ung VA at WATTS ( apparent power at true power) ay equal…

The only appliances that have low power factor would be those with motors and magnetic ballasts. New CFL bulbs (always good to check the box) have a power factor of 0.98, which is more or less close to perfect.

New air conditioners and refrigerators have also substantially improved in performance, but the bottomline is, it is so hard to prove that you have saved as electricity use is more or less the same anyway.

The best and only effective way of saving energy is through the use of energy monitors, unplugging chargers when not in use, unplugging appliances on Standby, keeping the air conditioner running at 25 degrees and having a small fan circulate air instead. These little changes can indeed give large savings.

I actually do have a blog where I post advice on going green called greener philippines, you can check out a lot of information there.

The real power (kW) doesn’t change at all. Apparent power (kVA) is reduced (hypotenuse becomes shorter). With voltage being constant at 220 RMS, this means that the current has been reduced, hence the result of the demo meter reading that the salesman at Handyman or Ace Hardware are trying to show us. Unfortunately, we are billed for Real power, not Apparent power.

EMER CAMAYA, YOU REALLY EDUCATE US THE PRODUCT WHAT WE ARE BUYING.YOU ARE A BIG HELP FOR US.HOPE YOU KEEP IN TOUCH HERE.IS THERE ANY WAY TO LESSEN THE REAL POWER? YOU MEAN TO SAY ,,,POWER SAVER CANT HELP US REDUCE OUR ELECTRICITY BILL? CAN U PLS. HELP US OR ADVICED US WHICH PWR SAVER WE ARE GOING TO BUY?TNX GOD BLESS U AND YOUR FAMILY

i do make that kind of devices, but it only works on appliances with motors.

Well, what happened to Yuga? We should be hearing from him for updates since he started this topic.

I just bought a powermax for 2k in Farmers, Cubao. A little bit higher than what was posted here. However, they have a free anti-mosquito bulb, so I guess I’ve got the same price also. Anyway, I’ll monitor my consumption for 3months since this was the guarantee that is they’ve committed to the customers. I’ll will give post again after I receive my next bill.

It’s sad that it didn’t work for others but for me PowerSaver has been very effective. Before using this, my usual Meralco bill is around 4000-5000pesos but just a month after using it my bill went down to 2400-2700pesos and I didn’t even lessen my use of the aircon at home since it’s summer. I notice that from the usual 300-350kwh, my monthly usage became 215-250kwh (HUGE Decrease!!!). I don’t care about the principles behind this little machine but for me what’s important is it really works.

I Agree with AAA Family. plugging more than 1 power saver will not be propotion to the household consumption unless you monitor them with Clamp meter. Power factor in this case will likewise will have no effect. Capacitance is is the key to this gadgets. As friendly advice, unplug your power saver during the day when no lights or aircon is used.

my mom and i bought this product today at ace hardware at ali mall. i’m still a bit skeptical and i have NO idea how to monitor it (unless i see next month’s bill).

but then the guy at the hardware store said that if this little device didn’t work, we can always go back there, bring the statements and then ask for a refund.

well, that’s what he said anyway~

Follow up on my experiments.
I got a new energy data logger that acquires more data than the previous power meter. The power saver max (PSM) only affects the power factor (PF) and only VA (Volt-Amp) takes into account the PF while Watts does not. Distribution companies like Meralco charge us by the kilowatt (1,000 watts) per hour we use. In conclusion the PSM will not lower your electric bill. I got this data on an 1.2HP air conditioner and an 80-watt electric fan. I have yet to do this on a refrigerator.
There are other ways to save on electricity like energy management and renewable energy. Reply to this post if you want to learn more.

hi, i am a german engineer and could’t believe this to be true. Anyway, i was curious and bought this yesterday at the SM but i was assured that i could return it and buy something else.

Okay, here is the measurements i did today.

I used a volt, watt and ampere meter and tested the device with both my aircon and computer station with all the other devices turned on.

The result is exactly what i expected. The power consumption is ecactly the same, however the ampere did go down a bit. What does this mean?

This means the electrical bill will be exactly the same. The device for sure is not real and worth nothing.

The sales trick in the mall was simple. They measured the ampere instead of the power consumption. Real devices that you use at home do have build in condensators to compensate the so called blind, reactive or wattless current.

This test also assured me that all those unbelieveable amazing products are absolutely worthless. Tomorrow i’ll go back to the SM and will return the divice.

Spend your money on San Miguel, Cheers.

I wanna buy one to try it!!! Is d brand of d power saver significant? where to buy a real psm aside from handyman?
I really wanna buy one coz my monthly bill ranges to 12k-15k monthly. That is about 1600kw to 2k kw monthly. Am using a 2.5(2750watts i guess) AC and a 13 units of desktops.electric fans, irons and d lightings.
Advise me what to buy pls!!! Thanks!

I really wanna try it but need further studying b4 gettin’ one…coz my csin uses one and it works..its just that there’s no one selling it in here i guess..
Am locted in cagayan valley! is there anyone near to me selling new one? pm me.. 091527*****
@ luckster
Then what could we probably do to save e-bills aside from being practical. here’s my add. samilinfrede****@****.***!

@ moonlightbill
It didn’t really work at all?

We are paying by the real power which is in watts, installing capacitor will improve the KVAR, and the KVA but never on the real power.

its a toast in the electrical bout these power saver,,im too curious bout since im also an electrical engineer and so many friends asking me bout these device,,,it will be nice if the measurement taken is in wattmet not in current.

how can i purchased this gadget when i am in catbalogan samar is there any outlet that i can buy this item if you have a net cafe with 11 units of pc and a i horse power of air conditioned how many units that i need to buy to save more of my money

sa quiapo mas mura daw 1,000 php lng,di kaya peke un?o pareho lang?

If you want to cut down electricity expenses, energy conservation and efficiency is the number 1 step.
1. Kill phantom loads (search the internet about this)
2. Buy energy efficient appliances particularly those that have high wattages and used often like refrigerator, washing machine, and air conditioners. Usually more expensive but will save you in the medium term. (I have a way to compute the ROI based on the EER, reply to this post if you are interested)
3. Change your life style. Turn off appliances and lights when not in use.
4. Convert to CFL or LED bulbs.
5. Improve your homes insulation and air flow. Invest on the right insulation.
6. etc.. etc..

Wala bang paraan para hindi na mag bayad ng kuryente sa meralco? Halos hindi ko na kayang magbayad.. Wala ba dyan no pay power saver max? Kung meron please tell me kung saan makakabili.

kahit saan po toh ilagay pwede halimbawa nakalagay yung saksakkan ng computer doon sa una tapos naka lagay yung power saver doon sa huli dapat po ba una ang power saver ???? oh kahit saan basta nakalagay lang po ??

gumagamit po kmi ng power saver max..bakit wla naman difference sa binabayaran namin ganon pa din.. dati 3500-4000 bill namin bakit ngayon 4800 na almost 1year ko na gamit minsan ko lang bumaba bill namin nag 3800 ata nung december.kz di masyado gamit ng aircon.. pano ba magandang pagamit sa power saver to lower your electric bill?

tira kayo probensya nang malaman nyo kung bakit maatas bill nyo sa kurente… hindi sa pagamit nyo ng appliances kundi sa scheme ng Meralco… maraming hidden charges na hindi mo naman DAPAT bayaran…. hehehe

guys,power saver is power corrector device,pag marami losses electricity m malaki savings m..

dalawang bese na ko nagsauli ng power saver na to. Ang unang buwan ay nagreduce ng kaunti ang bill ng 10%, sumunod lumaki ng 30% kaya ipina-check ko sa brother ko na isang electrical engr. at advise nya ay isoli ko sa binilhan dahil hindi nagpa-function. After having a new one, later on the next month billing ay tumaas pa ng 20% ang aming electricity bill.
Recommend not to purchase this product.

I officially retired my ORIGINAL POWER SAVER MAX unit when I bought the 5KW unit. It still functions though reducing from .95 to .79 the current ampere reading at the Handyman at Gaisano Mall of Davao.

The original unit is a 3KW model which saw our electric bill go down by more than 50% from P5,800 to P 2,700, of course our inductive load then was the 1.25 HP aircon, refrigerator, electric fan (1),lighting load, with resistive loads comprising the rest.

Our total load now is 2 x .75 HP Aircon units, one 8 kg washing machine, refrigerator, and 3 units electric fan, for the inductive part. CFL Lighting for the lighting load, 2 shower heaters
1 desktop and two laptop units, one rice cooker and one electric kettle, three cellphones, and one unit power quality analyzer.

Our current consumption reaches 600 Kwhs when climate change unleashes its might, and goes down to 500 kwhs when the rains fall and the aircon units just undergone cleaning. :)

Compare that with our consumption of 750 – 900 kwhs per month when we were still one aircon unit three years ago.

dti,3000 ngayon,sa sobrang galing ng power saver,wala na kaming binabayaran,sila pa ang nagbabayad samin!

i’ve been using power saver for almost a year me pumunta sa haus namin nataon malaki bill namin so sinubukan ko so far ok naman pati brother ko bumili din 7,500 bili namin kala ko nung una naloko kmi pero maganda naman pala bawi na investment ko.

Igot myself a differentpower saver guarranteed to save me 50% of my bills it has a ten ampere rating and i used it in my ten unit internet cafe. Truly it worked according to promise. Five years after it got busted but i do not know where to buy it again. Its brand is “Power Ace” made somewhere in Caloocan. Any lead to where i can buy that plug-in device that has a 220 volt socket? It looks like a low profile AVR.

We have PowerSaver Extreme and our experiment was very positive. We saved 40% to 50% monthly. We recommended it to our relatives and friends and they reported the same with PowerSaver Extreme.

So yes, it works, however, I can not say the same for PowerSaver Max since again, we have the Extreme version.

I’m interested your gadget in reducing my electric bill.
