It comes with a wireless remote with a whopping eighty foot range. Turn on the generator so that the air conditioner has already cooled down the RV on your way back from a hike or turn off the generator from a distance as you realize it is still running as you walk away.
The Champion 75537i generator has several RV ready outlets. It has a single 120 volt 30 amp RV outlet. It has two 120 volt 20 amp outlets suitable for smaller appliances and a 12 volt DC outlet.
The inverter unit has THD (power distortions) of less than 3%, so it is safe to use to charge your cell phone or laptop or run a smart TV. It puts out enough power to run a major RV air conditioner but little else, but it can run multiple other appliances if you don’t have an energy hog plugged into it. Champion offers a three year limited warranty through most sellers. When you send it in for service under the warranty, it may take weeks before you get it back. Its lifetime technical support is more a gray area.
This inverter generator is cheaper than the Champion model 75537i. The biggest advantage of this unit is the ability to conserve propane and burn gasoline; it is also suitable for powering key appliances in your home off of gasoline if there is a power outage or providing power to your cabin.

2 Powerful Inverter Generators on the Market Today
6000 Watt Inverter Generator
7000 Watt Inverter Generator
The manufacturer sells a cheaper 2200 watt inverter generator that costs less, or you can buy the “power pack” that provides both the 2200 watt and 3000 watt generators with a connector to link them and your RV, home or cabin together. Or you can buy your own parallel cable connector cable for this brand of generators for around $70.
One of the benefits of the Briggs & Stratton 30545 generator is the large one and a half gallon fuel tank. It can run your generator for ten hours. It comes with four household outlets for powering that many different items assuming they total up to the load the generator can provide.
It comes with a single 12 volt 30 amp outlet (with RV compatible DC charging outlet) and a USB port. While it has a USB port, it doesn’t have the same level of power quality as Champion’s portable generators.
Note that it is not as efficient as some of the Champion models and cannot be sold in California.
The manufacturer offers a two year limited warranty. Customer service for a Briggs & Stratton RV generator is far worse than that of Champion, since even getting a hold of the company is a challenge.
This is an affordable portable inverter generator. It puts out a constant 2800 watts and handles surges of up to 3100 watts. The WEN brand 56310i generator is CARB compliant – you can buy it and use it if you live in California. It produces clean power with relatively little variation safe for powering your tablets and smart phones. This generator is ideal for a modern family with multiple smart devices, since it has two separate 5V USB ports for charging your devices.
In contrast, most generators have only one of those charging ports. It also has a single 120 volt 30 amp receptacle, two 3 prong 120 volt plugs for plugging in standard appliances and a single 12 volt DC plug.
The nearly two gallon gas tank lets it run for up to eight hours. It naturally economizes fuel, but at full load, it will run closer to four to six hours.
This unit is portable. Just pull it along by the convenient carry handle. And unlike the Champion models, you don’t have to lean down awkwardly to drag it by a handle connected to the side of the generator. The manufacturer provides a basic two year warranty.
Westinghouse is best known for its power plants and home appliances. The model WH2200iXLT generator continues the company’s tradition for quality. This is one of the lighter portable generators on this list (43 pounds).
It puts out around 2000 running watts. The unit is EPA and CARB compliant, eco-friendly and legal to sell in California. It lacks an idle or remote to turn it off when not in use, so it is either on or off.
Its fuel tank only holds 1.3 gallons of gas but is so efficient it can run for up to eleven hours. You can connect it to another WH2400i or WH200iXLT inverter generator. The cords to do so are sold separately from the generators.
It comes with 2 USB ports and has less than 3% THD, making it safe to recharge two cell phones simultaneously.
This Honda EU2000i portable generator only runs on gas. It runs best on premium fuel. If you use other types of gasoline, note that you shouldn’t use fuel with more than 10% ethanol.
It comes with Honda’s three year limited warranty. A common problem with this model is the challenge of starting it up again if it sits idle too long. And you have to pull a cord to start it.
The inverter generator is louder than Honda advertises. You can use it at a campsite or on the RV, but you don’t want it running while the AC is blasting unless you don’t care about the noise.
It puts out 2000 watts at peak load but expect to be able to power 1800 watts worth of appliances off of it when running. In that regard, it isn’t as powerful as most of the inverter generators on this list.
One of the benefits of this portable generator is that it can be as quiet as 57 dB – one of the quietest portable generator on this list. It is also lightweight for a generator and compact; this is the ideal choice when you want to take along a generator in case you need it.
This Yamaha EF2200iS generator has a Twin Tech parallel function allowing you to connect two units together to provide 30 AMPs of rated power. It will run up to 10.5 hours at 1/4 rated load on a tank of gas. It is also easy to drain dry for storage. It has a fuel guage so you know how long the generator can run for without guessing.
Don’t use this generator at elevations above 4,000 feet. This warning is in the manual but often not communicated to buyers. And the manufacturer considers the warranty void if you try to install a high altitude kit.
Summary
The Champion model 75537i is a good choice for running multiple appliances or electronics and being able to turn on and off as desired. The model 100263 inverter generator by Champion is the best choice for those who want a portable generator that can power their homes or anything else using whatever fuel they have on hand.

The Westinghouse generator is the best choice for those who want a backup generator on the back of the RV or in storage until needed. Honda offers a basic generator whose only drawbacks are using the traditional pull-start and noise. The Yamaha generator is an ideal choice for those who want an portable generator as quiet as possible.
Inverter Generator Vs Conventional Generator
In the comparison of the inverter generator vs conventional generator, the first thing to understand is the difference between the two. Conventional generators are what we’ve had for decades. The gas or propane powered motor is attached to an alternator that generates AC power, though some deliver DC power. The frequency of the power fluctuates along with the RPM, making this type of generator risky to use to power electronics because power spikes could damage the sensitive electronics.
Inverter generators use an inverter alternator; it produces three phase AC power that is converted to DC power and then inverted back to AC power. The power produced through this process often has less than 3% total harmonic distortion (THD), making it safe to power a modern laptop computer, smart phone or big screen TV. Smart electronics will fry if THD exceeds 6%.
Inverter Generator FAQ
Q: Is an inverter generator better than a conventional generator?
A: Yes, there are several reasons why people are prepared to pay more for an inverter generator. This is primarily because this type of generator supplies clean power with low Harmonic Distortion (HD). This prevents damage to electronic equipment. Just about all modern appliances have electronic circuits and microprocessors. It’s not just TVs and computers that are sensitive to high levels of harmonic distortion. Most microwaves, refrigerators, washing machines, and air conditioners, have electronic controls. If an appliance has touch pad controls, or an LCD screen, it has electronic components. For this reason, inverter generators are growing in popularity.
Q: What are the advantages / disadvantages of an inverter generator?
A: There are several advantages to using an inverter generator:
A: Though inverter generators are not without their disadvantages:
Q: Do inverter generators use gas?
A: An inverter generator has a gas engine and an alternator like any other. Inverter generators differ in that the Alternating current (AC) power generated by the alternator is first converted to direct current (DC). The inverter then converts this power back into AC. The reason for this is that inverter uses a sophisticated computerized management system to monitor the load and the output current, maintaining a nearly perfect sine wave. So, while many inverter generators may use less gas than conventional equivalents, they all require gas for the engine to run.
Q: What is the best use / application for an inverter generator?
A: An inverter generator can be used in situation where one would use a traditional gas generator. Though they are best suited to powering electronic devices. These generators are popular for emergency home power, RVs, offices, and food trucks.
Q: What is the most powerful inverter generator on the market today?
A: The Honda EU7000iS is the most powerful portable inverter generator available. It has a peak (surge) output of 7,000 watts and continuous rated running power of 5,500W (120V/240V). It is also one of the quietest and most fuel-efficient generators on the market. The Yamaha EF6300iSDE has the same rated (continuous) power of 5,500W, but has a lower peak output of 6,300W.
I mean no disrespect, but not mentioning that all gas generators should be run on ethanol free gas is foolish not to mention. Ethanol free gas can sit for long periods and worth the extra .25 cents for generator fuel.
As far as the Honda generator, it should be #1 all day everyday and twice on Sunday for it’s rock solid dependability. While I don’t own Honda gensets, lots of my friends and family do, and their reputation speaks for itself.
The Honda generator and even Ryobi 2200 watt inverter generators are hard to start due to inactivity because of the design, it must be cold cranked a few times to prime the engine. ANYONE that owns a Honda or Ryobi and most <3000watt inverter generators without a remote start know this.
It shoulda been also noted, that most inverter generators can use tri fuel adapter so they can run on gas, propane or natural gas, these adapters are sometimes called snorkels. On sale they can be as low as $79
I live in West Florida, and I'm always prepared with lots of ethanol free fuel, a couple inverter generators and a portable AC. When Irma hit, it hit hard, I had to loan out all my generators and fuel to elderly neighbors less prepared that had to power medical devices. I sat in the dark with my two cats. But it was the right thing to do.
I wonder why there’s no mention of The Hyundai HY7500 inverter generator. It may actually be the most powerful, and less expensive than Honda from what I’ve researched.
