Crompton Optimus 65L Desert Air Cooler Review: Under ₹10,000

3.8(1,500 reviews)

The Crompton Optimus 65L is the only desert cooler under Rs 10,000 with an auto-fill feature that connects directly to your home water supply, eliminating the hassle of manually refilling a 65-litre tank. The Everlast pump is specifically engineered for high-TDS Indian water conditions common in North India, addressing the number one reliability concern with desert coolers.

The auto-drain function flushes stale water to prevent bacterial buildup, solving the bad-odour problem that affects coolers left idle for even a few days.

Decision Snapshot

The verdict, who it fits, and where to think twice — before you scroll the deep review.

Our Verdict

The Crompton Optimus 65L justifies its Rs 9,000-10,000 price with the auto-fill feature, Everlast hard-water pump, and auto-drain bacterial prevention that no other cooler under Rs 10,000 offers. The 5,500 CMH airflow covers rooms up to 650 sq ft effectively.

The trade-off is sitting right at the budget ceiling and requiring a nearby water supply connection for the auto-fill feature to work.

Best For

Homeowners with a water supply point near the cooler location who want truly hands-free operation without manual refilling in large rooms of 400-650 sq ft.

Watch Outs

Renters or those without a water supply connection near the cooler placement area, or buyers who find Rs 9,000-10,000 too close to the price ceiling.

Editor's Take

What it's actually like to live with

The Crompton Optimus 65L is the only cooler here that solves the biggest annoyance of desert cooler ownership - manual refilling. Connect it to your home water supply and the auto-fill system keeps the 65-litre tank topped up automatically. No more dragging a hose across the room or lugging buckets. For a cooler that runs all day in peak summer, this feature alone justifies the Rs 9,000-10,000 price.

The Everlast pump is engineered for Indian hard water conditions, and the auto-drain function is a genuinely clever addition. Stale water sitting in a cooler tank breeds bacteria and creates that unmistakable musty smell within days.

The auto-drain flushes it out, keeping your cooler fresh. At 5,500 CMH airflow, cooling performance for rooms up to 650 sq ft is solid if not class-leading.

The practical catch is that you need a water supply point near where you place the cooler.

If your cooler sits near a bathroom or kitchen wall with accessible plumbing, the setup is straightforward.

If your hall is in the middle of the house with no nearby water connection, the auto-fill feature becomes useless.

For homeowners with the right plumbing setup, this is the most hands-free desert cooler money can buy under Rs 10,000.
