What You'll Learn
Use a portable power station
If you want to run a TV without electricity, one option is to use a portable power station. These devices can store and supply electricity for various appliances and devices, and they can be especially useful for camping, emergencies, or outdoor activities.
The first step to choosing a portable power station is to figure out how much power your TV and other devices need. The power consumption of a device is typically measured in watts (W) or kilowatts (kW). You can find this information in the TV's user manual, on its label, or online. For example, a typical 32-inch LED TV may consume about 40 watts of power, while a 55-inch OLED TV may consume about 100 watts of power.
Once you know the power consumption of your TV, you can compare it to the power output and battery capacity of different portable power stations. The power output of a portable power station is the maximum amount of power that it can supply to your devices at a given time, and it is also measured in watts or kilowatts. The battery capacity of a portable power station, on the other hand, refers to the amount of energy that it can store and use, and it is measured in watt-hours (Wh) or kilowatt-hours (kWh). You can usually find this information on the label, manual, or online.
When choosing a portable power station, it is important to consider both the power demand and the running time. The power demand is the amount of power that your devices need, and the running time is the amount of time that you want to run your devices. For example, if you want to run a 70-watt TV and other devices for 4 hours, you need to make sure that the power output of the portable power station is greater than or equal to 70 watts, and that the battery capacity is sufficient for 4 hours of use.
Additionally, keep in mind that some appliances may have a higher surge power or startup current, which can be two to three times their normal operational capacity. So, it is recommended to have some extra watts available on your portable power station to accommodate for this.
Overall, portable power stations can be a great way to keep your TV running without electricity, but it is important to carefully consider your power needs and choose a station that is suitable for your specific devices and usage habits.

Try a 12V TV
If you want to run a TV without electricity, one option is to try a 12V TV. Many LCD TVs run on 12V batteries, and you can also connect them directly to a car battery or a 12V power supply. However, it's important to note that a 12V battery alone is not sufficient to power a TV; you also need to consider the amps required to run the set.
Some TVs have a power supply with a line voltage input and multiple outputs. If you want to input 12V directly, you would need to provide all the required voltages. One option is to use an inverter, which can be more efficient than converting between AC and DC power. However, there may be some voltage loss, and it's important to consider the current and power requirements of your TV.
If your TV has a 110V AC power cord, you cannot bypass the cord and plug it directly into a 12V socket. However, if your TV has an "inline" converter, you may be able to bypass the cord and plug the TV directly into a 12V socket, such as a car lighter socket. Be sure to read and understand the specifications of the inline power cord adapter to ensure compatibility and safe operation.
Additionally, you can consider purchasing a TV specifically designed for automotive or marine use, as these models often operate with a 12V source. Alternatively, you can look for a TV with an external power supply that outputs a single DC voltage, which can be more efficient and convenient.
Finally, if you experience frequent power outages, you may consider investing in an Uninterruptible Power Supply (UPS). A UPS provides temporary battery backup and supplies AC power to connected devices during outages. However, most UPS systems are only rated for a few minutes, so a whole-home generator with UPS may be a more suitable option for longer power outages.

Get an inverter
An inverter is a device that converts direct current (DC) into alternating current (AC), allowing you to connect appliances like a television to a power source other than your electrical grid, such as a vehicle battery. This can be especially useful during power outages or in areas with unreliable electricity access.
When choosing an inverter to run your TV, there are a few factors to consider:
- Power consumption of the TV: Televisions typically don't consume a lot of power, so you won't need an extremely powerful inverter. A 100-watt to 200-watt inverter should suffice, but you can determine the exact power usage of your TV to be sure.
- Inverter efficiency: Inverter efficiency refers to the energy loss during the conversion of DC to AC power. Inverter efficiencies typically range from 80% to 90%. A more efficient inverter will result in longer TV running time.
- Battery capacity: The size of the battery connected to your inverter will impact how long you can run your TV. Larger capacity batteries provide longer power supply times, while smaller ones offer shorter usage times. Battery capacity is typically measured in ampere-hours (Ah), and vehicle batteries usually range from 40 to 100Ah.
- Inverter size: Inverters come in various sizes, ranging from 50 watts to 50,000 watts. For household use, inverters under 11,000 watts are typically sufficient.
- Inverter type: Pure sine wave inverters are recommended as they provide reliable and clean power compared to modified sine wave inverters. However, a modified sine wave inverter can also safely power an LED TV.
By considering these factors and choosing the right inverter, you can enjoy uninterrupted TV entertainment even during power outages. Remember to calculate the power requirements of your TV and any additional devices you wish to connect to ensure you purchase an inverter that can handle the load.

Solar panels are an option
To run a TV using solar panels, you will need to determine the wattage requirements of your TV. TVs come in different sizes and technologies, each with specific power and energy requirements. You can usually find the power requirement information in the documentation that came with your TV or on a label on the back of the TV.
Once you know the wattage requirements of your TV, you can calculate the number of solar panels needed to run it. For example, to run a 50W TV for 6 hours per day, you would need one 100W solar panel and a power station that can store 400Wh of energy.
There are a few ways to set up a solar-powered TV. One method is to use solar generators or power stations combined with solar panels. Solar generators come in different capacities and sizes to suit your needs. They can store energy to power your TV even at night, during rainy weather, or on cloudy days. Another method is to use solar panels connected to a solar charge controller, which is then connected to a deep cycle battery or battery pack. This setup can store more energy but may be more complex and have slightly lower energy efficiency than solar generators.
By utilizing solar panels, you can power your TV without relying on traditional electricity sources, reducing your utility costs, and ensuring a consistent source of entertainment during blackouts or emergencies.
