What Size Of Power Inverter Do I Need To Run A TV?

Power outages can be unpredictable, but it’s essential to have a backup plan. A power inverter can be an excellent solution for powering small devices like televisions and fans in the event of a disrupted power supply.

If you’re in the market for a new power inverter, you must know what size you need to run your TV. While most TVs only require a small inverter, some larger models may need a more powerful one. In this blog post, we’ll discuss what size inverter you need to power your TV and answer all the questions in your mind about power inverters.

What Size of Power Inverter Do I Need to Run a TV?

While it does depend on what kind of TV you have in your home, you won’t find many bulky CRTs today. The most common variant is the slim 42-inch television. If you need to run an LED screen, you require no more than 80 Watts of power. LCD and Plasma have heavier power drains at 120 Watts and 220 Watts.

Therefore, you need an inverter that delivers at least 50% more to account for other appliances and inactive drainage. Still, power is just one part of the picture. The voltage and current supply also come into play. The higher the voltage of your inverter, the longer you can run your TV. In contrast, the current needs to fall in a suitable range for your TV.
