Before investing in a 2500 watt generator you want to find out what it will run and whether you need something stronger.
If you want to know about the upper limits, a 2500 watt generator can run devices like smaller AC systems, certain circular saws, and electric grills.
You can also choose to run multiple small to medium-sized appliances at the same time.
For example, a 2500 watt generator should be able to power devices like a refrigerator, sump pump, TV, and dishwasher at the same time.
Ideally, you want to figure out the exact starting and running watts your appliances and tools require and what continuous watts the 2500 watt generator you have in mind offers.
The table with appliances below can help you get a rough idea but keep in mind that different brands of devices can still vary.

What can a 2500 watt generator run?
Before checking out the list of examples of tools and devices 2500 watt generators can run you want to know a few things.
First of all, the watt requirements below are for the individual devices.
If you want to run multiple options at the same time, you want to look at the guidelines later in the article.
Something else to note is that 2500 peak watt generators can have different amounts of running watts.
For the table below, I will assume your 2500 watt generator offers at least 2200 running watts but keep in mind that there are also models with less capacity.
Lastly, the watt requirements below are just rough general guidelines. Individual brands can vary.

What will a 2500 watt generator run at the same time?
You will likely already realize that a single 2500 watt generator will not be able to run all the appliances above at the same time.
That being said, you likely also don’t have to stick to just one of these devices.
By following the steps below you can figure out what things your 2500 watt generator will run at the same time:
- Write down what appliances and tools you want to power.
- Find or measure the running and starting watts of each of these devices.
- Add up the running watts of the devices. Your generator needs at least this amount of running watts (or you need to run fewer devices at the same time).
- People who don’t mind changing in what order they start up their devices can order their devices from highest peak + running watts to lowest. Calculate whether the 2500 watt generator would be able to deal with this sequence.
- A simpler and more flexible calculation is adding up all the running watts and adding the single highest starting watts to this. This has to be below the 2500 watt capacity of the generator.
By doing this, you would find out that a 2500 watt generator can run appliances like a refrigerator, dishwasher, a few light bulbs, a coffee maker, a blender, and a TV at the same time.
It is worth noting again that what your 2500 watt generator will actually be able to run still depends on your startup order and appliance brand models.
Specific appliances and tools FAQ for 2500 watt generators
Many people also have certain appliances and tools in mind when considering a 2500 watt generator.
You can find some examples of these below.
Will a 2500 watt generator run a refrigerator?
Some refrigerators will need more power but an average model will need around 2200 starting watts (including 800 running watts).
That means 2500 watt generators will be able to run some but not all refrigerators.
Will a 2500 watt generator run a furnace?
A 2500 watt generator can likely start a 1/3 HP furnace fan blower.
Since you will likely need a stronger model for anything more than that, it is fair to say that a 2500 watt generator will typically not run a furnace.
Will a 2500 watt generator run an RV air conditioner?
An 11,000 BTU air conditioner needs around 1600 starting watts (this includes 1010 running watts).
However, since stronger models need more watts, you can only say a 2500 watt generator will run some but not all RV air conditioners.
Will a 2500 watt generator run a 13,500 BTU air conditioner?
Both regular and RV 13,500 BTU air conditioners tend to need more than 2500 watts to get going.
In turn, you can say a 2500 watt generator will typically not run a 13,500 BTU air conditioner.
Will a 2500 watt generator run a 5,500 BTU air conditioner?
Since 5,500 BTU air conditioners will typically need less than 1000 watts to get and keep going, a 2500 watt generator will generally be able to run these.
Will a 2500 watt generator run a skill saw?
While it depends on the individual model, there are skill saw that only need 2300 watts to get going.
At the same time, there will also be skill saws that need more than this.
In turn, a 2500 watt generator will be able to run some but not all skill saws.
Will a 2500 watt generator run a camper?
Whether a 2500 watt generator can run a camper depends more on the specific devices you intend to use than the camper aspect.
That means a 2500 watt generator will be able to run a camper with a limited amount of small to medium appliances or even certain sizes of AC systems.
On the other hand, there is also still a limit in terms of what this size of generator can power.
Will a 2500 watt generator run a freezer?
Brands and sizes can vary but the average freezer only needs around 1800 watts to get going and around 200 watts to keep going.
That means it is fair to say a 2500 watt generator will be able to run many models of freezers.
Will a 2500 watt generator run a TV?
Flatscreen TVs only require 120 watts and even a tube TV only requires 300 watts.
A 2500 watt generator should definitely be able to run a TV.
