A TV’s wattage ranges from 30 watts for a 32-inch LED to 200 watts for a 75-inch OLED. The two factors that determine consumption are screen size and display technology. LED and QLED TVs are the most efficient at 0.8 to 1.2 watts per inch of screen diagonal. OLED TVs use 1.5 to 2.5 watts per inch because every pixel produces its own light.
Wattage Table
| Type | Running Watts | Startup/Peak |
|---|---|---|
| 32-inch LED | 30-45W | 30-45W |
| 43-inch LED | 50-65W | 50-65W |
| 50-inch LED | 60-80W | 60-80W |
| 55-inch LED/QLED | 65-90W | 65-90W |
| 65-inch LED/QLED | 80-120W | 80-120W |
| 65-inch OLED | 100-150W | 100-150W |
| 75-inch LED/QLED | 110-160W | 110-160W |
| 75-inch OLED | 150-200W | 150-200W |
| 85-inch LED | 180-250W | 180-250W |
Look up any appliance in our Appliance Wattage Database covering 140+ devices. For the most accurate measurement, use a plug-in watt meter for 24 hours.
Daily Energy Consumption
To calculate daily energy cost, multiply the wattage by the hours of daily use, then divide by 1,000 to get kWh. Multiply by your electricity rate. For example, a 1,500W space heater running 6 hours per day uses 1,500 × 6 ÷ 1,000 = 9 kWh. At $0.15/kWh, that costs $1.35 per day or about $40 per month. Our Electricity Bill Calculator computes this for all your appliances combined.
Running on Battery Backup
To run this appliance on battery during a power outage, size the battery using our Battery Backup Calculator. Enter the wattage and desired runtime — the calculator outputs the exact battery size, inverter kVA, and solar panel count needed to sustain it. For generator sizing, use our Generator Sizing Calculator.
Running on Solar
To power this appliance entirely from solar, you need enough panels to produce the daily energy consumption plus system losses. Our Solar System Calculator sizes the complete system from your appliance list. Enter every device you want to run and it outputs the panel count, battery bank, inverter, and charge controller specifications.
How to Measure Actual Wattage
The wattage values above are typical ranges. Your specific appliance may draw more or less depending on age, condition, settings, and model. The most accurate way to measure: plug a watt meter (Kill A Watt P4400 or Poniie PN2000, both under $25) between the appliance and the wall outlet. Leave it connected for 24 hours to capture the full duty cycle including startup surges and standby consumption. The watt meter displays running watts, peak watts, and total kWh consumed — giving you the exact numbers to enter into our calculators.
Impact on Your Electricity Bill
To estimate the monthly cost of any appliance: multiply the average wattage by the hours of daily use, divide by 1,000 to convert to kWh, then multiply by your electricity rate and by 30 days. At the US average rate of $0.16/kWh, a 1,000W appliance running 4 hours daily costs about $1.92 per day or $57.60 per month. A 100W appliance running 8 hours daily costs about $0.13 per day or $3.84 per month. Small wattage differences add up significantly over a year — a 50W savings running 8 hours daily saves $23 per year. Use our Electricity Bill Calculator to see the combined cost of all your appliances.
Solar and Battery Sizing for This Appliance
When sizing solar panels or battery backup for this appliance, use the average consumption (not peak) for energy calculations and the startup surge for inverter and generator sizing. The daily kWh consumption determines how many solar panels you need. The peak surge wattage determines the minimum inverter or generator size. Our Solar System Calculator handles both calculations — enter all your appliances and it outputs the complete system specification including panels, battery, inverter, and charge controller.
For battery backup specifically, our Battery Backup Calculator shows how long any battery will run this appliance. For generator sizing, our Generator Sizing Calculator accounts for the startup surge to recommend the correct generator kW rating.
