The short answer
Buy the Atomberg Renesa BLDC for any fan that runs long hours — the electricity savings are real and the remote is genuinely useful. Buy the Bajaj when upfront budget is the constraint or for rooms used a few hours a week.
Running cost: where the Atomberg wins
The Renesa's BLDC motor draws roughly 28–35 W at full speed against 70–80 W for a conventional induction fan. Run 12 hours a day, that gap is ~0.5 unit daily — about ₹1,200 a year per fan at ₹7/unit. A bedroom fan effectively refunds the price difference in two summers, then keeps paying you.
The Bajaj counters with simplicity: no electronics in the motor, decades-proven design, and any local technician can service it.
Everyday use
- Speed control: the Renesa's remote gives 5 precise speeds + sleep/timer modes; the Bajaj uses a wall regulator.
- Power cuts: on an inverter, the Renesa runs 2–3× longer thanks to its low draw.
- Noise: both are quiet at normal speeds; induction fans develop hum with age, BLDC stays consistent.
If you want app + voice control on top, step up to the Renesa Smart+ — same motor, adds Alexa/Google.
Verdict
- Daily-use rooms (bedrooms, living room): Atomberg Renesa — the running-cost math is decisive.
- Guest room / occasional use: Bajaj — spend the savings elsewhere.
- Smart-home households: Renesa Smart+ slots straight into a voice-controlled setup alongside smart switches.
