TV Plasma 55-inch Wattage for Generator Sizing
About the TV Plasma 55-inch
An older 55-inch plasma television. Plasma TVs draw significantly more power than modern LED models, up to three to four times as much. While plasma TVs are no longer manufactured, many households still use them. If you have a plasma TV and are sizing a generator, be aware of the higher power requirement compared to current LED models. Upgrading to an LED TV would free up over 200 watts of generator capacity for other uses.
Generator Sizing for a TV Plasma 55-inch
Running a tv plasma 55-inch by itself requires a generator with at least 375 W of capacity (1 kW), which includes a 25% safety margin. However, you rarely run a single appliance on a generator. When combined with other appliances, the tv plasma 55-inch contributes 300 W to the continuous running load.
The tv plasma 55-inch is a resistive load, meaning it uses a heating element or simple electronic circuit rather than a motor. Resistive loads draw the same wattage from the moment they turn on until they turn off, with no starting surge. This makes them the easiest type of appliance to run on a generator. When calculating your total generator load, the tv plasma 55-inch adds a flat 300 W to your running total with no impact on peak surge calculations. Resistive loads also produce a power factor of 1.0, meaning they use electricity very efficiently with no wasted reactive power.
To determine the total generator size you need, use our interactive calculator to combine the tv plasma 55-inch with your other appliances. The calculator automatically handles the starting surge calculation and applies the 25% safety margin to give you an accurate recommendation.

Tips for Running a TV Plasma 55-inch on a Generator
Running a tv plasma 55-inch on a generator is straightforward since it is a purely resistive load. There are no special starting procedures or surge considerations. Simply ensure your generator's continuous (rated) wattage exceeds 300 W plus the wattage of all other appliances running simultaneously.
Since the tv plasma 55-inch draws a constant 300 W whenever it is operating, you can accurately predict generator fuel consumption. At typical generator fuel efficiencies, running the tv plasma 55-inch continuously adds approximately 0.0 gallons of gasoline per hour to your fuel consumption. If the tv plasma 55-inch operates intermittently (like a thermostat-controlled heater), the actual fuel impact will be lower.
For sensitive electronic components within the tv plasma 55-inch, an inverter generator provides the cleanest power output. However, most resistive appliances work fine on conventional generators as well. If you are running the tv plasma 55-inch along with sensitive electronics like computers, the inverter generator protects all connected devices.
