What Sizes Do Portable Generators Come In?

Portable generators come in various sizes and capacities. Of course, bigger sizes do not always mean higher capacities. By that, we mean that a smaller portable generator may sometimes generate a higher wattage than a bigger generator. So, it is better to focus on the capacities.

And portable generators come in various wattage capacities. You can find portable generators with the following capacities:

  • 200 watts
  • 250 watts
  • 300 watts
  • 350 watts
  • 400 watts
  • 500 watts
  • 750 watts
  • 1000 watts
  • 1500 watts
  • 2000 watts
  • 2500 watts
  • 3000 watts

How Big of a Generator Do I Need for a 2500 Square Foot House?

People often choose their generator based on the size of their house, but this is not accurate. What matters more is knowing all the appliances in your house. Sometimes, a bigger house may have fewer appliances than a smaller house. On that note, if you choose a generator for houses based on their size, you’re likely to get it wrong.

So, to know the size of a generator for a 2500 square foot house, find out all the electrical appliances in the house. Find out the wattage required by each of the appliances. You can then total the figures. That should give you an idea of the size and capacity of a generator you need.

This is not applicable to only 2500 square foot houses. Rather, it is applicable to every house. The size of the house plays a little role in determining the size of a generator.

Will a 15000-Watt Generator Run a House?

Even if you have a heavy work tool, this size of generator should be able to power it easily. We understand that it costs a fortune to purchase a 15,000-watt generator. So, it may be a complete waste of money if you purchase this generator when a smaller and cheaper generator can easily power your house.


  • You can use this to power all the household appliances you need to run during a power outage. You’ll be able to run your fridge, AC, home security system, lights, TV and sound system, your PC, and even your beloved coffee machine.
  • When you’re camping with an RV, the generator can make sure your RV is as comfy as living at a regular house. Just because you’re at a campsite doesn’t mean you have to make do without the (electronic) comforts of home.

Buying Guide – How to Choose the Best Rated Large Portable Generator?

Picking one among our 12 recommendations may still take you a while, and there’s always a chance you’ll pick wrong. To help make sure you get it right, you should consider the following factors:


The kinds of appliances you can run, along with the number of appliances you can power, will depend on the number of watts you get from the generator.

This means you need to add up the watts needed by the appliances you plan on running if there’s ever a power outage. You should get both the starting watts and the running watts totals.

The nice thing about a large generator is that you do get many thousands of watts. However, there’s a difference between getting 7.000 watts and more than 10,000 watts. With more watts, you pay more and you have to deal with greater weight and noise levels.

Run Times:

You can expect a large generator to run for a long while, especially if you don’t power too many watt-hungry appliances. But putting in a full load for the generator can shorten the time frame.

A longer run time before refueling is obviously better, and you should get one that can run for at least 8 hours straight if you plan on using a generator overnight.

Safety Features:

These can include automatic low oil shutoff and circuit breakers, as well as warning lights and voltmeters. It’s also nice if you have rubber covers on the outlets.

The safest ones are also the generators that you can use easily. So you should find out what using one entails, as complicated generators may not be best for you.

Noise Levels:

Large generators will make noise, and that’s the main drawback of having too many watts at your disposal. If you want your generator to be comparatively quieter, check for EPA approval and the reported decibel level. If the manufacturer isn’t saying anything about the noise, expect it to be noisy.

Do be sure that you won’t annoy people with the generator you use. You may even find the noise level intolerable, and that may not be great if you plan on using it while sleeping.


The more watts you get and the larger the generator you buy, the more you will likely spend. That’s why you should only get a generator with the watts you need, so you don’t pay for watts you don’t really use at all.


If it’s a portable generator, then it should at least have wheels and a handle. But the weight will be a factor to consider if you’re using this for a campsite.

Lifting a 200-pound generator from the trunk may be difficult if you’re alone. That’s the problem with large generators that offer many thousands of watts—they can be very heavy indeed.


Look for the warranty as a clue regarding the durability of the generator. Usually, these things have a warranty of a year, so a longer warranty may indicate greater durability and reliability.


A portable generator can make life a lot more comfortable at home even when there’s a power outage. As it’s portable, you can even bring one to a construction work site for your power tools or to a campsite for your TV, lights, and electric fan.

You can even have proper coffee with your espresso machine! Just pick the right one, or else you’re going to waste your money. A large generator may be more expensive, but it can be a proper investment in the long run.
