Twenty-five stabilizers at one chain, and the number on the front of the box turns out to explain nothing about the price. The two numbers in brackets underneath explain almost all of it.
We read twenty-five voltage stabilizer listings on croma.com on 15 September 2026 and tested the number every shopper uses: the amps rating on the front of the box. It explains nothing. Across the twenty-two listings that state both figures, amps and price correlate at -0.08 — the cheapest fifteen-amp unit here is Rs. 1,414 and the dearest six-amp one is Rs. 5,389. The number that does explain this shelf is the working voltage range in brackets, which correlates with price at +0.71. Seven twelve-amp units for the same air conditioner sell 2.3x apart.
Every price below was pulled from Croma on September 15, 2026 and checked against the MRP on the listing. Stack them with the live codes on our Croma coupons page, which the deals desk re-verifies daily.

First: read the bracketed voltage range before the amps number. On this shelf the window width predicts the price at +0.71 and the amps rating at -0.08, so the figure on the front of the box is the least informative thing on the tile. Second: find out what your supply actually does before you pay for range. The gap between a 170-270V unit and a 130-280V one was Rs. 2,575 on two otherwise identical twelve-amp listings here, and forty volts of headroom you never use is Rs. 2,575 wasted. Third: distrust the deep badge. Median badge on the narrow-window band was 39 percent and on the wide band 25 percent, and both of the one-rupee discounts on this page sit on wide-window boxes. Fourth: check the rating count, not the stars — only four of twenty-five listings here cleared ten ratings. Our guide to Croma EMI and delivery covers how the larger tickets get paid for and how long installation takes.

Twenty-two of the twenty-five listings state both an amps rating and a working voltage range in the title, so both can be tested against what Croma charges. The amps rating and the selling price have a correlation of -0.08 — statistically, no relationship at all. The clearest proof is on the shelf itself: the cheapest 15 Amps unit costs Rs. 1,414 and the dearest 6 Amps unit costs Rs. 5,389. More than twice the rating, for a quarter of the money. Whatever the amps number is telling you, it is not telling you the price.
Subtract the low figure from the high one in each title — 170-270V is a 100V window, 130-300V is a 170V one — and the picture resolves. Window width against price correlates at +0.71. Grouped into bands: the six narrow 100-110V units have a median price of Rs. 1,736, the nine mid 120-135V units Rs. 2,799, and the seven wide 145-170V units Rs. 3,154. You are buying how far the mains can fall before the box stops holding, and that is the specification worth reading.
Seven of these twenty-five are 12 Amps units for a 1.5-ton air conditioner — the same number for the same job — and they sell at Rs. 1,999, Rs. 2,490, Rs. 2,799, Rs. 2,994, Rs. 3,849, Rs. 4,124 and Rs. 4,574. That is a 2.3x spread. The six 15 Amps units spread wider still, 3.3x, from Rs. 1,414 to Rs. 4,615. We seated every member of both groups rather than picking one, because the group is the finding.
It points the opposite way. Median badge on the narrow-window band is 39 percent; on the wide-window band it is 25 percent. The two listings carrying no discount at all — Rs. 1,889 against a Rs. 1,890 MRP, and Rs. 5,389 against Rs. 5,390, one rupee each — are both wide-window units. The deepest badge on the shelf, 82 percent, sits on the cheapest thing here. A big badge on this aisle is a signal about the list price, not about the protection.
Croma published a rating count on 21 of the 25 listings, but most are in single figures — several show a bare '5.0' from two buyers, and one shows 1.0 from one. A star average with a sample that small cannot be weighed against anything. So a star pill appears on the four listings that cleared ten ratings and nowhere else on this page. We did not plug in, open or measure a single unit; working ranges and cut-off claims are the sellers' own.
Croma's own listings answer the amps part for you — the seven units sold for a 1.5-ton air conditioner in this read were rated 12 Amps, and a handful of 9 and 11 Amps units claim the same duty. The part the amps number does not answer is price, because those seven 12 Amps units sold at Rs. 1,999, Rs. 2,490, Rs. 2,799, Rs. 2,994, Rs. 3,849, Rs. 4,124 and Rs. 4,574. What separates them is the working voltage range: the Rs. 1,999 unit covers 170-270V and the Rs. 4,574 one covers 130-280V. Pick the amps from the appliance and the window from your supply.
Not on this shelf, and not in the way most people assume. Amps describes the current the unit can pass, so it has to match the appliance — but it is almost useless as a guide to price or capability here. Across the 22 listings stating both figures, amps and price correlate at -0.08. A 15 Amps V-Guard sold for Rs. 1,414 and a 6 Amps V-Guard for Rs. 5,389 on the same page on the same morning — 3.8 times the price for 40 percent of the rating. The window width, by contrast, correlates at +0.71.
It is the band of incoming mains voltage the unit claims to correct, printed in brackets in the listing title — 170-270V, 130-300V and so on. A wider band means the box keeps holding as supply sags further, and it is what this shelf actually charges for. Grouped by band, the six narrow 100-110V units had a median price of Rs. 1,736, the nine 120-135V units Rs. 2,799 and the seven wide 145-170V units Rs. 3,154. Three of the 25 listings state no range at all, which on this aisle is the most important omission a title can have.
Read them with care, because on this shelf the badge runs backwards to the specification. Median badge on the narrow-window band was 39 percent; on the wide-window band it was 25 percent. The deepest badge in the read, 82 percent, sits on the cheapest listing on the page. Meanwhile the two units Croma discounts by exactly one rupee — Rs. 1,889 against a Rs. 1,890 MRP and Rs. 5,389 against Rs. 5,390 — are both wide-window boxes. We quote MRPs because Croma displays them, not as evidence of money saved.
Only on a few of them. Croma published a rating count on 21 of the 25 listings in this read, but the samples are mostly tiny — several tiles show a bare '5.0' from two buyers, and one shows 1.0 from a single buyer. Only four listings cleared ten ratings: a 12 Amps unit with 62, an 11 Amps unit with 45, an Arizor 4170 with 26 and a 4 Amps fridge unit with 12. Those four are the only cards on this page carrying a star pill. Everywhere else we report the price and leave the stars alone.
