FAQ

1

Why is refrigerator average power different from running power?

Average power is not the same as running power because a refrigerator does not operate continuously. The compressor automatically switches ON and OFF based on cooling demand.

When the compressor is running, a typical LG refrigerator consumes:

  • 120–250 watts when the compressor is ON
  • 0–5 watts during standby or OFF mode
  • 600–1200 watts briefly during startup (surge power)

The commonly quoted 62 W value is a time-averaged power calculated over a full day. It does not mean the refrigerator constantly uses 62 watts.

A simple way to understand this is to imagine a 60-watt light bulb running all day. In reality, the refrigerator:

  • Runs only about 25–40% of the time
  • Consumes around 150–200 watts when actively running

This ON–OFF operating cycle is why refrigerators are energy-efficient while still having higher instantaneous power when the compressor starts.

What is the average electricity consumption of common household appliances?

Below is an approximate electricity consumption table for common household appliances based on industry standards. Actual usage may vary depending on brand, efficiency rating, and usage duration.

Appliance Typical Power (Watts) Avg. Usage (Hours/Day) Daily Consumption (kWh)
Refrigerator (300–400L) 150–250 8–10 (compressor) 1.0–1.5
Air Conditioner (1.5 Ton) 1400–2000 6–8 8–12
Ceiling Fan 60–90 10–12 0.6–1.0
LED TV (43–55") 80–150 4–6 0.4–0.9
Washing Machine 500–700 1 0.5–0.7
Microwave Oven 1000–1500 0.3 0.3–0.5
Water Heater (Geyser) 1500–3000 1–2 2–4
LED Light 7–12 6–8 0.05–0.1
Laptop 50–90 6–8 0.3–0.6
Desktop Computer 200–400 6–8 1.2–3.0
Inverter (with battery charging) 100–600 4–6 (charging + load) 0.4–3.6

These values are commonly used for electricity bill estimation and energy-audit calculations.
