The Most Efficient Way to Use Your TV
More or less, it only takes 1 ampere to power a regular flat television. That is why you can have a functioning medium-sized television in an RV van. However, it is worth finding out the power that your television requires so that you could manage your TV usage and electricity consumption while looking out for the TV that would suit your viewing needs.
Other than amperes, there are other factors that come to play in powering your TV. For instance, a 50-inch TV with a good diagonal display will require 200 watts. This means that if you are plugging your TV to 120V, it would need 1.6 amps. Inversely, if your TV requires 240V, its amperage requirement would be lower or halved at 0.8 amps. Basically, this means that at a higher voltage, your TV would require lesser amperes, the measure for electrical current.
Additionally, in terms of energy consumption, expect a large variation among different television manufacturers and within a manufacturer’s range of TV models. Consider as well how old your TV is. In 2011, TV manufacturers were required to carry an Energy Guide label to help users understand the power requirements of their TV.
Power requirements depend as well on the display size, brightness settings, display technology, and integration of features such as Internet and Smart TV capability. For instance, a brand new 55-inch Samsung UHD 4K TV would need 34 watts at 120V. On the other hand, a 5-year-old 40-inch HD TV would need 55 watts. Although a Samsung UHD 4K TV might cost you, in the long run, you get to save on energy consumption while having the best viewing experience.
