Propane is a popular fuel source for outdoor cooking, heating, and running generators. Propane tanks are available in various sizes, ranging from small, portable tanks to large, permanent tanks. One question often asked by those who use propane-powered generators is: How Long Will A 20lb Propane Tank Run A Generator? Let’s delve into this topic and find out the answer.
First of all, it’s important to note that the runtime of a propane tank depends on several factors, such as the size and efficiency of the generator, the load being powered by the generator, the outdoor temperature, and the altitude. However, as a general rule of thumb, a 20lb propane tank will run a generator for 10-20 hours, depending on these factors.
Let’s explore each one of these factors in more detail.
Generator size and efficiency:
The size and efficiency of the generator play a significant role in determining the runtime of a propane tank. A larger generator with a higher wattage output will consume more propane and run for a shorter time than a smaller, more efficient generator. Therefore, it’s crucial to choose a generator that matches your power needs while ensuring optimal fuel efficiency. Ensure that the generator is meant to run on propane fuel as well.
Load being powered:
Another factor that influences how long a 20lb propane tank will run a generator is the load being powered. A generator that powers a small load, such as a few light bulbs, will consume less fuel and run for a more extended time than a generator that powers a large load, such as a refrigerator or an air conditioner. It’s essential to identify the power requirements of the appliances you intend to power with the generator and select a generator that delivers the appropriate wattage to run them effectively.
Outdoor temperature:
The outdoor temperature also affects the runtime of a propane tank. Propane vaporizes into a gas when exposed to heat, and the rate of vaporization increases with higher temperatures. Therefore, if the outside temperature is high, the propane tank will run out faster than if the temperature is lower. However, take note, extremely low temperatures are also possible to reduce the performance of a propane tank.
Altitude:
Altitude is another factor that impacts the runtime of a propane tank. At higher altitudes, the air pressure decreases, which causes the propane to vaporize more slowly. Therefore, generators that run on propane at higher altitudes may experience reduced performance, which will, in turn, reduce the runtime of the propane tank.
In conclusion, the answer to the question, “How Long Will A 20lb Propane Tank Run A Generator?” is that it varies and depends on the factors mentioned above. However, as a general rule of thumb, a 20lb propane tank will run a generator for 10-20 hours, provided that you have a properly sized generator that is efficient in its use of fuel, powering the right load, you are in moderate outdoor temperatures, and at a lower altitude.
Now that we know the answer to the question, let’s remind ourselves of the precautions we have to take when handling propane tanks. They are highly pressurized and must be appropriately handled and stored to prevent accidents. It’s essential to ensure that the valves are closed and that the tank is secured in place to prevent any risks of tipping. We should also keep propane tanks away from flame or heat sources to prevent fires or explosions. Always consult your generator’s user manual and follow the manufacturer’s recommendations on how to operate and maintain the generator and the propane tank.
We hope this article gave insights on how long a 20lb propane tank will run a generator. Remember to take all necessary precautions when handling propane tanks and follow the manufacturer’s recommendations for safe use.

Frequently Asked Questions – How Long Will A 20lb Propane Tank Run A Generator?
1. How long will a 20lb propane tank run a generator?
It depends on the size of the generator and its fuel consumption rate. Generally, a 20lb propane tank can run a 5000-watt generator for up to 10 hours at half-load capacity.
2. Can I use a 20lb propane tank to power my whole house generator?
It may not be sufficient to power a whole house generator that runs on propane as it requires large propane tanks. However, you can use a 20lb propane tank to power a portable generator to run essential appliances during power outages.
3. Can I store a 20lb propane tank indoors?
No, it is not recommended to store a propane tank indoors as it can be hazardous. A propane tank should be stored in a well-ventilated area outside the house. Do not store it near heat sources or other flammable materials.
4. Can I refill a 20lb propane tank?
Yes, you can refill a 20lb propane tank at a propane filling station or exchange it for a full tank at a propane exchange location. Always remember to check the expiration date of the tank, and if it is more than 12 years old, it should not be refilled and needs to be replaced.
