Westinghouse iGen2500 inverter generator

The Westinghouse iGen2500 Inverter Generator is a small, but mighty generator that is ideal for use in an RV. It is lightweight (48 pounds) and comes outfitted with a carrying handle. This inverter generator has less than 3% total harmonic distortion (THD).

Its low THD levels make it a good inverter generator option for powering small, sensitive devices like laptops and tablets. Additionally, it is strong enough to power all essential home devices with 2500 peak watts (2200 watts running).

If you find that you need more power, this generator is parallel-compatible. You can connect it to another Westinghouse generator using an inverter parallel cord (not included).

This generator also boasts great fuel efficiency. If you’re running the Westinghouse iGen2500 at a 25% load, you can expect up to 10 hours on 1 gallon of gas. The fuel tank holds 1.3 gallons.

Moreover, it has a high-efficiency mode. When you activate this option, the generator automatically adjusts how much power it’s generating (and how much fuel it is consuming) based on what is plugged into any (or all) of its 4 ports: two 120-volt 20-amp outlets and two USB ports.

The safety features for this inverter generator make it an excellent option, too. It has low-oil shutdown, overload protection, and a built-in spark arrestor to prevent accidents. It is also EPA, USFS, and CARB-compliant.

With all of these features and its 98cc engine, it is still quiet. The Westinghouse iGen2500 comes with low-tone mufflers that keep sounds under control. The sound for this generator measures in at 52 dBA making it perfect for camping sites.

You’ll always know what’s going on with this generator, thanks to the LED data center. It has a rotating display that shows fuel level, power output, remaining run time, and voltage output.

Should you have any issues with your Westinghouse, it comes with 3 years of limited service, labor, and parts coverage. You also have access to nationwide customer service and support.

This generator may be small, but the power that it puts out gives it a big reputation. One complaint is that the process of “breaking in” the generator is more involved than anticipated. Otherwise, this is a reliable, portable, and powerful generator for camping and a whole lot more.

Pros
  • Ultra-light
  • Quiet
  • Fuel-efficient
  • Versatile
  • Clean energy
Cons
  • Complicated break-in process

Champion 3500-watt portable generator with wireless remote start

Meet the Champion 3100-watt portable generator’s big sibling, the Champion 3500-watt portable generator. This large unit makes the list because it has a few additional features that its predecessor does not.

To start, the Champion 3500-watt portable generator is wireless remote-start capable from up to 80 feet away. If you’re close, though, just use the touch start. These options already make the unit easy to use.

The 196cc engine makes it one of the more powerful generators on this list. Moreover, it uses an electric start system. If you’re in a cold-weather situation, no need to worry. This generator is designed with cold-start technology, so you’ll be up and running in no time.

The fuel tank on this generator holds almost 4 gallons of gas. There’s also an easily readable gauge on the control panel where you can see where your fuel levels are, too.

Cummins Onan (3.6KY-FA/26120) Micro-quiet LP Generator

If you want a generator that is going to work overtime for you, this is the one. The Cummins Onan micro-quiet LP generator is significantly more expensive (around 5x) than anything on this list. It boasts being able to run a 15,000 BTU air conditioner without using all of its power.

RV Generator Buyer’s Guide

We designed this buyer’s guide to help you answer all of the questions you have (and some you didn’t even know to ask) to help you make the most educated generator purchase.

The truth is that all generators are not created equally. They come in different sizes, shapes, power outputs, features, etc.

There are several criteria that you should consider when you’re about to purchase a generator. Each of the criteria poses a question to you, the buyer. Once you have your answers, they will point you to the generator that meets your needs and (hopefully) more. Those criteria are power, location, and fuel consumption.

Power

How much power do you need? We’ve established that you’ll be using your generator for RV use, so you’ll want to look for something that’s got enough power to run your most essential RV appliances and devices.

If you’ll be charging sensitive electronics, like cell phones and laptops, there are generators that handle those better. If you’ll be running a full A/C unit and a microwave, there are generators that handle those better, too. You just have to know the difference. In terms of power, there are two things you want to think about: Generator type and output.

Broadly speaking, there are two types of generators: standard and inverter. A standard generator has a basic engine that runs at a set speed from when you turn it on and ends when you turn it off. This works well for job sites or for events. It’s straightforward power.

Inverter generators use a microprocessor to monitor how the load changes when you increase (or decrease) it. It auto-adjusts the power output to an appropriate level as those changes occur. So, if you’re charging your laptop, microwaving a burrito, and watching TV, your output will be at one level. Once you finish microwaving that burrito, the power output adjusts to only needing to supply power to the TV and continue to charge your laptop.

Inverter generators are beneficial for things like microwaves and laptops because it prevents surges that could potentially damage your devices. (In this context, these are referred to as “sensitive” devices.)

Output is the number of watts that a generator puts out. You’ll usually see a larger number and a slightly smaller number. For example, the WEN 56200i is a 2000-watt portable generator. It outputs 2000 surge-watts and 1600 running-watts.

This means that when the generator has a full load, the max that it can output is 2000 watts. It can’t do this for very long, though. The lower number, 1600 watts, is when the generator is at 25% capacity. This load is what the generator will run at for the listed run-time. So, the WEN 56200i will run at 1600 watts for about 10 hours on a full tank of gas.

Check out our guide on how to find the right-sized generator for your camper to ensure you’ll never be left without power!

Location

Where are you running your RV? If you plan on camping with a generator, your generator needs to produce no more than 70 dBAs for you to avoid being asked to turn your generator off (or being asked to leave). These guidelines vary from park to park. Generally, though, a noise level between 60 and 70 decibels is an acceptable range.

did you know Did you know…

If it seems like your generator is louder than normal, it may be time for an oil change.

The location also brings portability into question. Will you be installing it for use exclusively on your RV? Or will you be using it for camping, as a backup power source during power outages, at job sites, or anything else? Generators are so versatile that you can find one that does some or all of these things, but you want to know what you’re looking for beforehand.

If you are going to install the generator, you should find an expert to do it for you. Generators provide power, and you don’t want to be stuck without it at a campsite. Some generators have complex installation instructions. You should also check its dimensions. Ensure that the generator you’re looking at actually fits into your RV before you purchase it.

Installations also come with separate fees. Keep that in mind as you consider how much you are willing to spend.

If you don’t want to install your generator, you’ll need to decide on whether to purchase a portable RV generator or not. Now, just because a generator isn’t labeled “portable” doesn’t mean that you can’t move it. It typically means that it won’t come with wheels and a handle installed.

In some cases, like with the Durostar DS4000S 4000-watt portable generator, it is portable but doesn’t come with wheels. They’re sold separately. Ultimately, a big question in “portability” is weight. Will you need to pick the generator up? If so, can you? Check out how heavy a particular generator is before you purchase it (if heavy lifting is not in your plan).

Fuel Consumption

Gas is the most common type of fuel for generators. All of the units in our list of generator reviews above are gas powered. However, some generators use liquid propane or diesel to power them. And some use two different fuel sources, like the Champion 3800-Watt Dual Fuel Portable Generator, which can operate on gas or liquid propane.

The important thing here is to understand how your power draw affects fuel. Again, using the WEN 56200i as an example: you get 10 hours of time on a 1600-watt load and a full tank of gas. This model carries about 1 gallon of fuel in its tank.

From there, it’s simple math. Take the number of hours that you will be using your generator and divide that by 10. That’s how much fuel you’ll need. Make sure that the number is worth it for you when you decide to purchase a generator.

Generator Maintenance

A crucial part of owning a generator is maintaining it. There’s no worse feeling than trying to start your generator after it has been stored away for the winter with no success. Practicing regular maintenance rituals will ensure that your generator is ready to go when you need it.

Here are the general rules for generator maintenance.

Fresh is best

When it comes to fuel, always get it fresh. Using old fuel can cause a build-up that is difficult and costly to repair. Fresh fuel is one way to ensure that your unit will run properly.

Regular oil changes

Keeping up with oil changes ensures that your generator is well-lubricated. Follow manufacturer guidelines on what type of oil to use and how often you should get your generator oil changed.

Clean your battery

Regularly cleaning your battery lines reduces build-up.

Get professional tune-ups

There are always things you can do to maintain your generator (like the suggestions we’ve made so far). Similar to a car, though, you should take your generator in to be regularly serviced by a professional. If you follow all of these guidelines, your generator should run smoothly for many, many years.
