These days, everywhere is talking about the power outage and its problems. From television and radio to everyday talks in the taxi and workplace, we are all concerned about electricity and planned silences in the summer. We hear the same fuss, colorful and tempting advertising as “Stabilizer Buy”. Some sellers say this device is comfortable with all the problems of electricity and you will no longer have to worry about the damage to expensive equipment. We, who do not know much about wires, cables, and transcripts, look at them openly and ask ourselves? Things are complicated when we take the story seriously and reach the price of stabilizer. So I helped an electrical technician to share his information with us and tell you what he said in a simple and practical guide.
What is stabilizer; Stabilizer function in simple language
Suppose the entrance to your home is a road full of hole and bumpy. These pits are the same voltage fluctuations that sometimes make electricity weak and sometimes strong. What is this magical device now? Stabilizer acts like a voltage guard that stands on the door of your home. The main task of this guard is to fill all of these pits and bumps and deliver a fixed voltage (usually 1V) your electrical appliances.
The important point is here; The task of this device is to fix the voltage only. This tool does not generate electricity. In order for this to be better, we need to know the difference with two other important means:
- Normal Power Protector: The guards act like a sleepy guard. Only when the voltage goes too high or too low, they wake up and cut off the entire electricity so as not to damage you, but they do not do anything in small and continuous fluctuations.
- UPS (UPS): UPS is a motivated and active guard who has a battery in addition to taking the voltage. At the time of power outages, the battery comes in and provides the power required for your devices for a few minutes or hours.
So it was summarized; The home stabilizer only keeps the voltage constant and can do nothing at the time of complete power outage.
Relationship of electricity fluctuations and hotliners’ hotlifting
Electrical fluctuations are a real and serious danger to electrical appliances. A severe voltage drop or a high instant voltage can damage the domestic inside of the expensive electrical appliances such as refrigerator, TV, or air conditioner. Sellers are doing exactly the same fear. They have created a hot market for themselves using the current situation and public concern about power outages and possible damage.
But we must be honest with ourselves. Sellers look the problem of voltage fluctuations with power outages. This is their most important marketing trick. In fact, they tell you, “Buy a stabilizer to keep your belongings safe from electricity problems”, while their original purpose is fluctuating, not power outages.

Behind the curtain of high price stabilizer; Factors affecting price
You may be asked why this device is priced several times as much as a simple electrical shield. There are various reasons for the expensive stabilizer:
Construction Technology: Stabilizers are divided into two main categories:
- Relay: These models use a relay to change the voltage. As a result, their performance is slightly delayed, and they are “pushing” when working. They are cheaper and are suitable for items like refrigerators and regular computers.
- Servo Motor: This type of stabilizers use a precise engine to adjust the voltage. That’s why they are more accurate and operate faster. They are suitable for sensitive and expensive equipment or use for the whole home, but they are much higher.
Power (VA or Wat): The higher the ability of a stabilizer, the more electrical appliances can cover. A useful device for the whole home must have a power of 1 to 2 kW, which directly affects its price.
Brand and Import: Credit and foreign brands are more priced than domestic brands due to the costs of import, customs and profits. It is always best to research the brand before buying and read users’ comments. In the Iranian market, Delta, Saco and Stabiller Faratel brands are more popular.

Does stabilizer solve the power outage?
No! In no way. This is the most important thing that should be the queen of your mind. Stabilizer does nothing at the time of complete power outage. When the electricity is cut off, the voltage stabilizer also disappears and does nothing. The task of this device is to manage the input voltage when the power is connected. So if your main problem is planned and for several hours, buying a home stabilizer alone cannot solve it. You need a UPS or generator system to do this.
How much of a stabilizer advertising is deception and magnification?
Now that you know the differences, you can easily understand the advertising claims. Be careful about deceptive advertising:
- “Don’t worry about the power outage with this stabilizer:” This sentence is a great deception. Sellers move the words with words so that customers consider the problem of voltage fluctuations with the problem of complete power outage.
- “Full Protection against All Electrical Problems”: This is an exaggerated claim. Stabilizer is effective in voltage problems, including increased voltage, but does not do anything or has limited efficiency against lightning or complete power cuts.
- “Buying a home stabilizer is essential for everyone”: This is also a kind of magnification. As we will say further, the voltage stabilizer is not necessary for everyone and many people do not need it.


Who really needs stabilizer; The final decision guide
Now that you know the truth of the story, it’s time to see if you really need stabilizer. My friend, who is an electrical engineer, says customers should be divided into three main categories:
The first group; Buying is essential
- People who live in areas with severe voltage drops: If you are in rural areas, the end of the power transmission lines or neighborhoods that constantly lower the voltage of electricity (for example, lamps flicker), buying a home stabilizer is essential.
- Very sensitive and expensive equipment owners: If you have specific medical devices, professional audio and video systems, or small computer servers, it is best to use servo motor models to protect them. People who have a medical equipment at home such as oxygen makers or ECGs or have small industrial workshops can also prioritize this purchase.
The second group; Purchase can be useful
- People who live in old wiring apartments: The old wiring can be the cause of the voltage fluctuation.
- People with only one or more expensive and sensitive electrical appliances: If, for example, you only have a very expensive gas cooler, OLED TV or a side -bybay refrigerator, you can get a good power stabilizer for the same device.
The third group; Shopping is probably unnecessary
- General in urban areas with relatively stable electricity grid: If you live in an urban neighborhood where the voltage is usually constant and you only have a planned power outage in the summer, you do not need to buy stabilizers. For you, a standard and high quality voltage protector is enough for refrigerators, TVs and other home appliances.
Conclusion
In the end, let’s review the key points again.
Stabilizer Faratel or any other famous brand is just a voltage stabilizer, not a power generator. It protects your belongings from voltage fluctuations, but does nothing when the power is completely cut off. The voltage stabilization market has been hot due to people’s fear of damages during fluctuations. Sellers integrate the fluctuation problem with the power outage to increase their sales.
Before purchasing an expensive device for the whole home, first know the real problem of your home’s electricity grid. If your problem is only planned power outages, it will launch a high quality bodyguard.
Remember, you have come up with a specialized and efficient tool to solve a specific problem (voltage fluctuation), but you should not confuse it with a magical solution for power outages. With this information, you can now decide with full confidence whether buying a home stabilizer is a need for you or an extra fee.
