Finding the right power source for entertainment on the road can be tricky. When figuring out how big an inverter to power a 32 tv, the answer lies in the wattage. Most modern 32-inch LED TVs draw between 30 and 50 watts. In our tests, we found that while a 150W inverter is technically sufficient, a 300W unit offers the necessary headroom for startup surges and additional devices like streaming sticks. We evaluated the market to find reliable units that keep your picture clear and your battery safe.
Our Winner: BESTEK 300W Pure Sine Wave Power Inverter
This unit strikes the perfect balance between performance and price. It delivers clean power that prevents static lines on TV screens, a common issue with cheaper modified sine wave models.
Technical Benchmarking & Field Testing
In our technical analysis, we evaluated these units based on sine-wave stability, high-temperature durability, and low-voltage protection. We prioritized models that meet UL 458 safety standards for mobile applications. For a television, waveform quality is critical to avoid audio buzz or visual artifacts.

Frequently Asked Questions
How big of an inverter do I actually need for a 32-inch TV?
Most 32-inch LED TVs require between 30 and 50 watts of continuous power. We recommend a 300W inverter to ensure the unit runs cool and can handle the initial startup surge, which can be briefly higher than the running wattage.
Can I plug a TV into a cigarette lighter inverter?
Yes. Since a 32-inch TV draws less than 100 watts, it is safe to use a cigarette lighter inverter (which usually supports up to 150W). However, ensure your vehicle’s fuse is rated for at least 15 amps.
Do I need Pure Sine Wave for a TV?
While many modern TVs work on Modified Sine Wave inverters, Pure Sine Wave is superior. It eliminates visual noise (lines on the screen) and audio buzzing. For long-term use, Pure Sine Wave is recommended to prevent component stress.
Conclusion
Selecting the right inverter depends on your specific usage. For a quick and easy solution, the SUPERONE 150W is perfect for the occasional road trip. However, for the best viewing experience without interference, the BESTEK 300W Pure Sine Wave is our top recommendation for powering a 32-inch TV efficiently.
