Best Voltage Stabilizers in India Reviews & Buying Guide 2020

Voltage fluctuations are very common in India. It is more evident in summers when you can see the fans slowing down, AC not cooling and lights go on and off. If may seem no big deal, as it happens too often. But in reality, it heavily damages devices. And you see the result when your devices expire much sooner than what is expected.

High voltage can permanently destroy the electrical device where low voltage can bring deadly risks like short circuits and burring out. Burning out of an AC while sleeping is not also a very rare case.  So the best way to keep your devices safe from these voltage hazards is to use a proper voltage stabilizer.

Here are the two most important factors before buying a voltage stabilizer-

Voltage fluctuation range in your area: You will choose your stabilizer depending on the fluctuations in your locality. If it varies between 90V-300 or more means high voltage fluctuations. You need a powerful stabilizer. Between 130V-290V is medium and 170V-270V low voltage fluctuations

Stabilizer Type: you just can’t go and pick any stabilizer. Deferent devices perform differently and there are different stabilizers for them. The most popular ones are-

  • Stabilizers for inverter AC
  • Digital Stabilizer for TV, LED/LCD, music system, etc.
  • Stabilizer for Refrigerator of different capacities
  • Stabilizer for Washing Machine, Microwave, etc.

We have selected 10 best stabilizers for AC, LED TV, Refrigerators, Washing Machine and, Microwaves. The selection was done based on customer reviews, customer needs, best brands and warranty services. We have also included a Voltage Stabilizer Buying Guide at the end of this article.

Voltage Stabilizer Buying Guide

Buying a voltage stabilizer is not easy. But we will make it easier. You need to know some basic things before spending your money on a stabilizer. There are basically two things to consider before you hit the market. First the power consumption of the devices you will connect and second the voltage fluctuation range and limits of your locality. Then comes the safety features, mounting options and many more. Let’s get into the details!

1. Know the Power Consumption of Your Devices

The foremost thing to do is know the power which will be connected from the stabilizer. Add up the power consumption of all the appliances to determine the total load on the stabilizer. The calculations will be done in watts. But most of the stabilizer capacity is measured in VA or kVA or Amps.  You will have to convert this into Watts in order to know the correct measurements. These total power ratings should match with the total capacity of your new stabilizer.

2. Know Voltage fluctuation Range and Limits of your Locality

Voltage stabilizers have different voltage operating range. An operating voltage is the voltage input which the stabilizer regulates or stabilizes and delivers a safe output voltage. So, it is important to consider the voltage range (fluctuation limits) of your locality and choose the stabilizer accordingly.

Note: Notice and make a note on the voltage fluctuations like extremely high, low or medium fluctuations. You may also talk to an electrician. For instance, if you experience wide voltage fluctuations in your area your stabilizer must need to have a wide voltage input range.

Here is a depiction of general wattage requirements of day to day electrical appliances

3. Mounting Options

You will be given a lot of options to choose from for mounting. But you have to choose the one according to your residential or commercial arena. Stabilizers may get damaged too, especially in wall or ground surfaces which get wet, heated, or simply anywhere which would affect the stabilizer in any way.

So, make sure to keep the stabilizer in a place which is safe enough. Choose a place away from moisture and heat and keep it away from children in the house. As in extreme cases, the stabilizer is prone to electric shock. The best thing to do is to choose a wall-mountable stabilizer. There are stabilizers have a compact body and elegant looks to match with your interiors.

4. Know the Safety Features of a Stabilizer

  • Time delay system

Many AC and Refrigerator voltage stabilizer are including this feature to maximize the safety of your expensive devices.

During short-time power cuts, the voltage keeps fluctuating for a while. This is not good for the compressor or your AC. Sudden voltage shocks during power cuts cause serve damage in the long run. A time-delay feature during short time power cuts waits for a stable voltage for 3-5 minutes and then delivers the output to the appliance.

  • Thermal Overload protection

There is always a risk of short circuits and burnouts due to overheating. A lot of stabilizer includes thermal overheat protection. This additional feature can save you and device from deadly accidents. This stabilizer can sense the excess heat and excess flow of current and immediately seizes the current flow.

Thereby turning off the faulty device and preventing any kind of severe damage. You need to reconsider the windings, as they have an effect and they are basically of copper, but you can also find some stabilizers with aluminium windings.

  • Indicators

It is better if your stabilizer comes along with the display of the input/output voltage. The indicators help the product display the voltage which has been generated and balanced by the stabilizer. You can keep a track of the voltage fluctuations levels and the performance of both the device. Almost all the stabilizer in our list has an indicator. They serve a great purpose for you when you actually start using it.

  • Digitized

You can always opt for a traditional stabilizer if you believe it is enough. But nowadays a lot of advanced models are being launched in the market which are entirely digitized to bring the best outcome of the product. The latest digitized stabilizers can adapt itself according to the connected device. All you need to do is shift the stabilizer mode to one device from another and it will adapt itself to the new device. With a digitized stabilizer, you can safeguard all your devices with just one stabilizer.

Frequently Asked Questions

1. Can the same stabilizer be used for AC as well as other appliances?

No! If you have a traditional rather regular stabilizer, you must not use it for AC as they both are not compatible with each other. An Air conditioner is in requirement of additional safety and hence, you need some additional built-in features to ensure both your stabilizer and the Air conditioning is safe. The additional features include, time-delay system often referred to as ITDS which makes sure the compressor of the AC has all the time for safety.

2. Will stabilizers save on electricity bills?

Such terms and conditions do not come with these devices; this is because stabilizer is no power saving unit or output. You can though expect saving up to an extent this is because the basic job of a stabilizer is to keep the power consumption stable and there are chances that some of the power may be saved in between the process. You may assume the stabilizer actually consumes its own fraction of power. The basic power wastage of a stabilizer is up to 5% in maximum, but if you use it on an excessive basis you may end up wasting up a lot more energy.

3. Do LED TVs need voltage stabilizer?

This purely depends on your perception of safety but if you ask for advice, the modern LED TVs do not necessarily need a voltage stabilizer in order to work. The reason for this is that TVs have the capability of working for a Voltage between 110 V and 290V. This is the reason why any of the fluctuations in the electricity would not affect the TV.

But there are some cases where the TV may get damaged, such as power surges and sudden spike in electric current. This is when you need a surge protector to save your TV, from such a sudden spike in electricity. In such a case you may choose to buy a stabilizer with a feature called surge protection.

4. What are some of the effects of voltage fluctuations?

You basically need a stabilizer when there is a lot of fluctuation in the voltage. You may notice a constant pattern of high and low fluctuations or may notice it all in a sudden especially after power cuts. But what stays constant is that your appliances will be prone to damage. The basic reasons for such fluctuations are bad wiring, overload, suddenly switching on or off high voltage devices, bad earthing or even short circuits.

5. Is there only one phased stabilizer?

There are different kinds of stabilizers as in different phased stabilizers. You will come across a one phased stabilizer and also a three-phased stabilizer. If you are in seek of residential use then a one phased stabilizer would suffice for your need. But in case you are looking to stabilize an entire house or a three-phase connection you are will need a three-phased connection. You need to dig deeper if you wish to know each and every aspect of the phase connections but hitting the web.


So, as you can see you need to have a basic understanding of few things before you can buy a stabilizer for your appliances. A stabilizer for AC can’t work on a refrigerator and vice-versa. Also, you need to know certain parameters like power consumption and voltage fluctuation etc to purchase the right one that can take the load of the appliance and even the input voltage.

Nevertheless, our top recommendation for ACs is the V-Guard VWI 400 Voltage Stabilizer for Inverter AC for TVs is the V-Guard Voltage Stabilizer for TV and for other appliances like refrigerators etc, it is the V-Guard VGSD 50 Voltage Stabilizer for Refrigerator As you can clearly see, all of them are from V-Guard. Be rest assured that we are not biased towards V-Guard. They actually make high-quality stabilizers and offers good customer service across India.
