How Many Watts Does a TV Use: 24, 32, 50, 55, 65 Inch TV and More [With a Data Table]

How Many Watts Does A TV Use?

The number of watts used by any TV will depend on its type. Here, we will include the different types of TV and their watts.

• CRT TV:These old technologies are bulky in size and consume up to 120 watts of electricity. However, many people use CRT TVs as they are great for gaming purposes without any blurry motion or input lag.
• Plasma TVs:They are made up of tiny gas pockets and light up when high voltage is applied. Plasma TV has an excellent contrast ratio and views, which consumes up to 500 watts of power.
• LCD:They are a great combination of picture quality and low power consumption. LCDs use cold-cathode fluorescent lamps for backlighting and consume around 70-200 watts.
• LED: While LCDs and LEDs use the same kind of technology, LED TVs typically use light-emitting diodes and are generally more economical.
• OLED:This latest TV uses organic light-emitting diodes and uses more power than LEDs.

The following table reveals how many watts does a TV uses depending on different sizes and types.

How Many Watts Does A TV Use Per Hour?

The hourly wattage consumption of TV will depend on the TV type, model, and size. Here's a table revealing the power usage per hour of different types of TVs.

How Many Watts Does A 32-Inch TV Use?

Most homeowners use a 32-inch TV because they are cheap, lightweight, compact, and easy to carry. The power consumption of same-size TVs will depend on the brand and its type. For example, a 32" LED TV will consume around 30-55 watts of power, whereas the 32" OLED uses 55-60 watts. The 32-inch LCD TV consumes higher watts, around 50-85 watts. The older 32" CRT TVs have the highest power consumption, which is equal to 150-200 watts, with an average of 170 watts.

How Many Watts Does A 55-Inch TV Use?

A 55" inch TV is the larger version of the previous models and is becoming more and more popular. Their consumption may vary depending on the TV type. For example, the 55" LED consumes around 60-90 watts, whereas the 55" OLED has a power consumption rate of 105-110 watts.

How Many Watts Does A Flat Screen TV Use?

A typical modern flat TV consumes anywhere between 50 - 150 watts of electricity. However, it may depend on the size and model of the TV. For example, if you are using a 32” LED TV, it will consume 30 - 55 watts of electricity. On the other hand, if you are using a 32” LCD TV, it might consume a higher wattage of around 50 - 85 watts.

How Many Volts & Amps Does A TV Use?

Volts and amps  are the essential terms that determine how much electricity flows or is used by any appliance.

• Volts (V):It is short for voltage and typically measures the difference in electrical pressure. In other words,  voltage is like the speed of electricity that passes through the circuit.

• Amps (A):It is short for amperes and generally measures the electrical current. It is the amount of electrons that flow through the circuit.

Typically, TVs use around 120-volt outlets. If the TV amps 164W of hourly wattage, the amperage will be calculated as follows:

Amps = 164W / 120V = 1.37 amps.

How Much Electricity Does A TV Use?

On average, most TVs use anywhere between 50 - 200 watts of electricity. However, the TV watts will largely depend on the model and size of TV you have. It’s safe to say most modern TVs draw 100 watts of electricity, whereas older models might be less efficient and draw anywhere around 200W.

How Much Electricity Does A TV Use Per Month?

If we suppose you've a TV drawing 100 watts of electricity and are watching TV for nearly 2 hours per day. This calculates to 1.4 kilowatt-hour of electricity per week or 6 kilowatt-hour per month. On the other hand, if you're using the same TV for 3 hours per day, the monthly electricity consumption will be 9.1 kWh per month.

Here's how you can calculate the monthly electricity consumption of a 100W TV yourself:

Electricity or Kilowatt-hour = Watts × Usage per day × 30 = 100W × 2H × 30 = 6kWh per month.

How Many Amps Does a TV Use?

Most TVs typically consume less than one amp when connected to a 120V outlet. Let's take an example where we will calculate the amps of a TV drawing 120 watts of electricity from a 120-volt outlet.

Amps = Watts ÷ Volts = 120W ÷ 120V = 1 amps.

What Are The Factors Affecting TV Wattage?

If you are wondering about how many watts does a TV uses per hour, you'll need to understand the factors that affect the TV watts.

Type of TV: Modern TVs and LED TVs are generally more energy-efficient than older models. Generally, Energy Star-certified TVs are 25% more efficient than conventional TVs.

TV Age: Like any other technology, the older an appliance gets, the more wattage it will consume. The CRT models use up to 120 watts, whereas the LED TV consumes 24-28 watts for small sizes and 90 watts for larger sets.

Size of TV: The larger TVs typically consume more energy than smaller ones. For example, a 48-inch TV consumes 80 watts of power. But how many watts does a 65-inch TV use? It is nearly 115 watts.

TV Usage: The more TV you use, the higher the watts consumption will be. It is best to switch off the TV when not in use to avoid higher bills.

Vampire Power: It's a term for how much power any device consumes when turned off but plugged in. TVs typically consume 5% of their usual power consumption, even in standby mode.

How to Determine The TV Power Consumption?

Most modern TVs, like LED or OLED, are more energy-efficient and have an ENERGY STAR-rated sign. It generally consumes around 150 watts. You can find the TV power consumption on the blank panel of the appliance. If, in case, you cannot find the wattage on the TV, multiply the maximum TV voltage and amperage.

Formula: Watts of TV × Hours Used = Power Consumption

Example: A 150-wattage TV appliance, when used for three per day, will consume 150W × 3H = 450Wh per day.
