What Amps Does a Television Need? (Cost, Power, & More)

These days, TVs’ power consumption specifications can be difficult to find. Lucky for you, I was able to find the manuals of six popular TV brands. Below are their details on power consumption.

What amps does a TV use?

American TVs are 50 inches in size and use 0.95 amps at 120 V. This amounts to an average TV power consumption of 113 watts. The average TV will consume 142 kWh per year and cost just over 17 dollars, assuming five hours of daily use.

American TV Size Average

Surprisingly, the American TV is a medium size. More than twice the growth between 1998 and today It can grow from 23 to 50 inches.

It is important to know the average size of a TV in order to calculate how many amps it uses. A smaller TV will consume less power, while a larger TV will require more.

Because larger TVs require more power, this is why it is so. A typical TV with an 85 inch screen consumes over 400 watts. A TV with a 43 inch screen uses only 100 watts.

You might think that larger TVs consume more power, but what does this mean for amperage?

Great question.

Amps, Volts, and Watts

I won’t go into the finer details of what amps, volts, and watts actually are. There are many great resources.

For our purposes, however, it is important to understand that amps = Watts/Volts.

The supply voltage at the power outlet in a typical American home is 120 volts.

Knowing that the volt part of our equation will always remain constant at 120 means that watts will ultimately determine how much amps the TV uses.

The greater the amperage, the more watts.

Televisions that are larger and more energy-efficient use more watts and, in turn, consume more amperage.

Take the Sony 50 inch X80J television. It consumes 146 watts. 146W divided by 120V gives 1.22 amps. This is almost twice the TCL 50′ 4 series, which uses only 79 watts.

As you can see, this is a significant expense that you will have to pay over the course of a whole year. The Sony 50″ is almost twice the price of the TCL to power.

Regardless of the TV model, TV costs are generally very low. There are also many factors that affect TV power costs.

What are the factors that impact TV power costs

You’ve likely seen a yellow Energy Guide sticker if you’ve been shopping for appliances in the last decade.

This sticker, which is required by law, details how much energy the appliance consumes and how much you will pay to power it for one year.

Like all appliances, TVs’ energy guide labels are based on only estimates. There are many factors that can affect the power cost of your TVs.

Take, for example:

1.What number of hours you watch TV per day. All estimates of TV energy costs assume that you use 5 hours per day. Your costs will vary depending on how much you use your TV. Even if your TV is used for 10 hours per day, your annual cost will still be 100.

2.Utility/power rates. Power rates are affected by where you live, and whether you have access to solar or other renewable energy. Energy guide calculations assume that electricity costs 11 cents per kWh. You may have higher or lower costs. Mine are, for instance, higher.

3.TV settings: The TV’s default picture settings are used to calculate the cost of your TV’s energy consumption. These settings use almost all the energy of every day.

1.Brightness/contrast is the most important TV setting that has an impact on power consumption. The more powerful your TV is, the greater its annual cost and the more power it uses.

2.You can also lower the volume of the TV or mut it during commercials. By doing this, your TV won’t be using power to sound while you’re not paying attention. It might be that you prefer peace and quiet.

3.Consider using the programmable sleep timer. This is ideal for people who fall asleep during a show or movie and then wake up in the middle of the night. Your TV will automatically shut off when you set the sleep timer.


Today’s average television size is 50 inches. This is up from 23 inches in 1998.

How many amps can a TV use if it is 50 inches in size?

An average 50-inch TV consumes 0.95 amps at 120 V. 113 watts is the average TV power consumption.

A 50-inch TV will cost you 17 dollars per year to power (142 kWh/year at 11 cents/kWh).

Larger TVs consume more power and, in turn, use more amperage. Amps are watts/volts.

In America, the volts equal 120.

A few factors can influence TV power costs, including how many hours you spend watching TV per day, the local power/utility rates and the settings of your TV.

This is why every person’s TV cost will be different, but even though yours are twice the American average, you’ll still only pay 34 dollars per year. It’s not bad.
