The math
| Usable capacity | 500 Wh × 0.85 = 425 Wh |
|---|---|
| Average draw | 80 W running × 1 duty = 80 W |
| Runtime | 425 ÷ 80 = 5.3 h |

Questions people ask
How long will a 500 Wh power station run a TV?
About 5.3 hours (about 5.3 hours). A 500 Wh power station has roughly 425 Wh usable, and a TV averages about 80 W. Depending on the model the range is about 2.1 to 8.5 hours.
How many watts does a TV use?
A typical 55-inch LED TV uses about 60-100 watts while on, roughly 80 W on average. Smaller sets can use 50 W or less; large or OLED sets with bright HDR can reach 150-200 W. There is no startup surge.
How do you calculate power station runtime?
Hours ≈ capacity in Wh × 0.85 ÷ average watts. The 0.85 allows for inverter and battery losses.
