3. How Many Hours Can You Run Your 3,000-Watt Generator?

The simple answer for that is it depends on what appliances you are turning on and the rated running hours of the generator you are using. Aside from that, the running hours also depend on the type of fuel used. We’ll explain it a bit below.

What appliances you are turning on

If you are using appliances that use a lot of wattage, then it may come to an end-result of shorter running hours of your generator. Let’s take an example for that: if you are using a fridge (170 watts), air conditioner (500 watts), and a laptop computer (45 watts), then your total need is 715 watts. Compared to that, turning on the whole house’s light circuit (500 watts), will save more fuel despite the number of lamps turned on.

Your generators’ rated wattage

If we are talking about best 3000 watt portable generators running wattage, then in most cases, your generator will have around 2,400-2,800 watts as its rated wattage (again, it depends on your generator!). 

You may have known that the more wattage you are using, then the shorter your generator will run. It is because the more fuel your generator is taking to bear out the needs. That’s why, despite the 3,000 watts, people are cutting down their electricity use because they don’t want to refuel their generator much often.

Types of fuel used

There are two kinds of fuel commonly used in generators: gasoline and propane. It puts your mind at ease when you are using a hybrid generator, which can work with both kinds of fuel. What if you are using that kind of generator that only works with one type of fuel? How many hours can you use your best 3000 watt portable generators?

  • Gasoline

Generators that work with gasoline will have limited running time, if compared to generators working with propane. However, the upside is it’s way cheaper than getting propane to refuel the generator. In general, the rated runtime of generator with this type of fuel is around a few hours to 12 hours, or even more.

You may think that you can refuel the generator directly when it is working. But hey, it’s a big no! Don’t refuel your gasoline generator when the generator is still running. It’s tempting to refuel it, isn’t it? But this is a dangerous thing to do as it may cause an unexpected bursting flame.

  • Propane

As aforementioned, the portable generator with propane can run longer. Why so, you can ‘link’ two tanks of propane to one gas line through a changeover regulator. As a result, you can turn on one tank while leaving the other still connected, yet closed. No need to be busy while switching between two tanks. Simply twist the valve, and you’re good to go.
