## How Long Will a 5-Gallon Propane Tank Run a Generator

When it comes to powering a generator with propane, the size of the tank is one of the most important factors to consider. A 5-gallon propane tank is a popular option for many homeowners because it’s large enough to power a generator for several hours, but not so large that it’s difficult to move or store. So, how long will a 5-gallon propane tank run a generator?

It depends on the size of the generator and how much power it uses. If you have a small generator that only uses 500 watts of power, your 5-gallon propane tank will theoretically last for 40 hours. However, if you have a larger generator that uses 2000 watts of power, your 5-gallon tank will only last for about 8 hours.

In reality, though, you’ll likely get less than these theoretical numbers because generators usually don’t run at their full capacity all the time.
If you want your 5-gallon propane tank to last as long as possible when powering a generator, there are a few things you can do. First, make sure your generator is properly sized for your needs.

There’s no point in having a powerful 10000 watt generator if you only need 1000 watts of power – you’ll just be wasting fuel. Second, try to use your generators at off-peak times when electricity rates are lower. This will help reduce the amount of time your generator needs to run and save you money on fuel costs.

Finally, invest in an automatic shutoff switch that will turn off your generator when the tank runs low on fuel.
