While a 3,000 watt generator won’t run every appliance in your home, it will go a long way towards keeping everyone comfortable and content in during a power outage.
When the power goes out, you can keep your family comfortable and your home running smoothly with a simple, gas-powered generator.
Three thousand watt generators can also be used for fun applications such as camping and entertaining.
A 3,000 watt generator can run most of your basic home appliances, such as your refrigerator, television, microwave, laptop, coffee maker, lights, dishwasher, small air conditioner, and even a space heater. You may need to pick and choose which appliances you can run simultaneously, but once you understand the starting and running watts of your generator, you’ll be able to figure that out easily.
In this article, we’ll explain the starting and running watts of your 3,000 watt generator.
We’ll look at how those watts work and help you figure out which appliances you can run on your generator and which appliances you can run simultaneously.
But first, let’s look at the difference between starting and running watts.

Starting Watts and Running Watts
Electrical output is measured in watts. All appliances that use electricity to run will have a required wattage, which you can find on the appliance itself or in the user’s manual. Typically, the larger the appliance, the more watts it will require.
The smaller the appliance, the fewer watts it will require. Appliances that use motors will require an extra boost of power to get the appliance started, known as starting watts. That extra boost of power is why you need to know the difference between starting and running watts.
Running Watts or Continuous Watts
Running watts, also known as continuous watts, are the highest number of watts your generator can run for an extended period.
For example, if you want to run a 75-watt lightbulb for 4 hours, the lightbulb will require a continuous 75 watts of electricity the whole time it is lit. When you purchase your generator, you should be able to find this information on the box or, at the very least, in the owner’s manual.
However, appliances that need motors typically need extra watts to get the motor running and then a smaller amount of watts to keep the appliance running.
Starting or Surge Watts
Starting watts, sometimes known as surge watts, are the extra watts an appliance needs to get running. Most appliances can supply extra surge watts for a few seconds, but the amount and length it can provide will depend on your specific generator. Again, you can usually find this information on the box of the generator when you purchase it.
Your 3,000 watt generator should have at least an extra 200 starting watts, but most will have even more. It just depends on the particular brand of generator you are running because they are all different.
You must have enough starting watts and running watts for all of the appliances you plan to run on your generator. If you don’t have enough starting or surge watts, you won’t be able to power up your appliances.
You also run the risk of damaging both your equipment and your generator, so always check your numbers to make sure you aren’t overtaxing your generator. Overestimating what your generator can run can be a dangerous and costly mistake.
3,000 Watt Generator Run Capabilities
Ideally, you won’t run your generator at more than 90% of its maximum running watts, or about 2700 watts. This will give your generator a little room to run efficiently. It also leaves a margin of error in case you miscalculated or in case your appliance happens to pull more watts than you expect.
However, a 3,000 watt generator can technically run 3,000 watts of machines simultaneously. You can run multiple appliances simultaneously as long as the total of their individual watts does not equal more than 3,000 watts.
For example, on a cold morning, you might want to run a few lights, your laptop and coffee maker, and a small space heater. Provided the total watts needed aren’t more than 3,000, you should be just fine to run all of those together.
On the other hand, if you are trying to run your water heater, you might be able to do so, but you won’t be able to run anything else with it. The water heater would require too many watts, and if you try to run more appliances with it, your generator will overload.
It could damage the generator and the appliances. See the chart below for an estimate of typical home appliance starting and running watts.

How Do You Know If Your 3,000 Watt Generator Has Enough Watts?
The chart above gives you a general idea of the number of watts your average appliances require to run. Your specific appliance could be a little bit different, but you can find this information on the box your appliance came in, listed in the owner’s manual, and on the appliance, as well.
Most of these appliances run easily on your 3,000 watt generator, but if you want to combine appliances, you’ll need to figure out the number of watts they need.
First, figure out the starting and running watts your generator can supply. For example, a 3,000 watt generator can deliver 3,000 watts continuously. The starting or surge watts will vary by model, but for this article, let’s just suppose your generator has 3,500 surge watts.
Examples of Running Multiple Appliances on a 3,000 Watt Generator
It’s early morning, and you need to get your day started. You need a light, cell phone charger, and your space heater to take off the chill. But can your 3,000 watt generator handle this? Let’s find out.
To know if your 3,000 watt generator can handle all of those items, you’ll need to figure out how many watts they each need to start and run and add them up. None of these items require extra starting watts, so you just need to add up the continuous or running watts:
- Space heater 1,800 watts
- Light 75 watts
- Cell phone charger 25 watts
In this case, the total watts comes to 1,900, so your 3,000 watt generator will have no problem taking on the tasks you need. If you need a cup of coffee, you could do that, too, since your coffee maker requires 1,000 watts. That would bring your total to 2,900 watts. Running these items together should be no problem for your generator.
Of course, if you are running your refrigerator with your 3,000 watt generator, you’re going to need to rethink your plan. A typical fridge will require 2,200 surge watts and about 700 running watts.
You might need to skip the space heater if you want to run the refrigerator, as well. If you need to, you could turn off the fridge for a short period while you run the space heater. Once you get a little bit warmed up, turn off the space heater and turn the refrigerator back on.
What Can’t a 3,000 Watt Generator Run?
A 3,000 watt generator can run most of your essential household appliances. It can even run a number of smaller appliances simultaneously. However, it won’t be able to run everything in your home.
A clothes dryer simply requires more watts than a 3,000 watt generator can supply. It also can’t run anything as hefty as a central heating unit, central air conditioner, and it probably cannot handle your electric range.
If you try to run these items, your generator won’t handle the amount of power required. It is never safe to overload your generator. It can cause damage to the generator, the appliances and might even start a fire.
