I recently purchased the V-Guard iD4 Ace 5540 AC Stabilizer for my 1.5-ton inverter AC, and I must say, it’s been an outstanding investment! The stabilizer is sleek and compact, and it does a fantastic job of keeping the voltage steady, which is essential for my AC's performance.The design is modern, and it’s built to last with high-quality materials. I’ve noticed a significant improvement in the efficiency of my AC since using this stabilizer. It protects the unit from voltage fluctuations and ensures smooth operation. The stabilizer is also very quiet, which is a bonus.Installation was easy, and the device works flawlessly without any issues. I highly recommend this stabilizer to anyone looking to protect their AC and improve its longevity. V-Guard has truly delivered with this product. Worth every penny!

Purchased it for 1.5 Ton Split Inverter AC (working Range 130-280 VAC).Timely delivered and Packaging is good condition.It is look very nice and review after one month it works accurately and efficiently with the input voltage and output i.e. performance was as expected.Display of voltage is in blue is good, but at the time of sleep this display blue light is too much bright in the dark bedroom.No noise issue, value for money. Overall, this product is very good.

The media could not be loaded. Intelligently actuates when voltage drops to 190...It gives sturdy +/- 3 voltsBoost / bucks up to 40 volts (practically seen)which is necessary for inverter AC ..Little noisy at nights when exhaust fan gets activated due to heat.This have photo sensor at ring when it day light it gets brighter and at night it gets dimmer.Also when voltage gets below 190 it changes colour blue to light pink & when it gets back to 210 volts it changes pink colour to blue colour,at autocut it turns in red colour.About 3 minutes delay start which is very necessary for AC.Weight about 7.5 kg.Looks nice with elegant design..Capacity -12 Amps (up to 1.5 ton inverter AC only)Working range -130 VAC to 280 VAC3 Years warrantyMaximum voltage is restricted up to 240 VAC at any condition which is very good function.Auto cut off high and low voltage.In market there are many brands but V guard has reputation and trust...I am using V guard stabilizer from last 6 years to LED television..no complaints till now ..Though it is costly but necessaryJust go for it..I got at ₹5050

Very Good color texture, looks is also great with blue right illumination.

1. The delivery person almost slammed my stabilizer, but I chose to ignore it at the time.2. The stabilizer arrived in standard Amazon packaging, not V-Guard’s original packaging, which seemed suspicious.3. The stabilizer makes a constant "tik tik tik" noise every minute, and it even affects my AC’s fan speed.4. How is anyone supposed to sleep with that constant "tik tik" noise going off every minute?5. It can’t handle minor voltage fluctuations, likely because the product is damaged.6. The stabilizer is unnecessarily large and not worth the money considering its poor performance tho build quality it quite good and it is heavy.This experience has been extremely frustrating!Never ignore small red flags like I did even if it's a urgent order as it may cost you much more than a mere 5000 inr in my case it could have costed me my precious AC and in such a case I would've surely sued V-guard and the seller.

Product is good but seller didn't send the screw and plug to hang

Good product recently purchased...Ease to use...

I am using this stabilizer for my Samsung 1.5 ton Inverter AC. It works very accurately and efficiently with the input voltage and output voltage. The digital meter automatically shows the input as "IP" followed by input voltage in numbers, after that it shows output as "OP" followed by out voltage in numbers. If the voltage goes above or below it's operating range of 140V-280V then it cuts off displaying red LED. Also the LED ring and colors look very elegant and cool.In my area the voltage generally remains low to medium, i.e 100V-220V or so. Thus, opted for this stabilizer for the safety of my AC. It has a auto cut-off feature which cuts off the electricity supply to the AC if voltage goes below 140V (generally I face this situation only in my area, have not faced the high voltage situation till now). Also, if AC is running and suddenly voltage goes low and then comes back to normal, the stabilizer has a time delay feature which lets the electricity to the AC only after few minutes for safety. This time delay feature is one of the most important feature in any AC stabilizer. It has copper windings which is great and a reason for it's higher budget.Installation is very easy. They provide a pair of long screws and guide on paper for drilling space in wall. It is quite heavy as expected. The wire provided is of right length, not very long, not short. Wire joining is quite easy.The product while scanned for authenticity came out wrong on VGuard Website. However, on inquiry, they told that it is anew model and as they do not have it's data on their website thus it is showing as not authentic. It is a valid product from them and I am happy with the purchase.
