Generator Buying Guide

In this guide, I’ll walk you through some of the key things to consider when purchasing a generator, as well as some tips to help you make the right choice for your needs.

Determine your power needs.

The first thing to consider when buying a generator is your power needs. Make a list of the appliances or devices you plan to power and their wattage requirements. This will help you determine the size and power output you need from your generator.

Choose the right type of generator.

There are two main types of generators: portable and standby. Portable generators are typically smaller and can be moved around, while standby generators are larger and are designed to provide backup power to an entire home. Consider which type is best for your needs.

Consider fuel type and efficiency.

Generators can run on a variety of fuels, including gasoline, propane, and diesel. Determine which fuel type is most convenient and cost-effective for you. Also, consider the generator’s fuel efficiency, as this will impact how often you need to refuel the generator.

Look for safety features.

Safety should be a top priority when choosing a generator. Look for features such as low oil shut-off, automatic voltage regulation, and GFCI outlets to ensure safe operation.

Evaluate noise level.

Generators can be loud, so consider the noise level of the generator before making a purchase. Look for models that have low decibel ratings or include noise-reducing features.

Check the warranty and customer support.

Make sure to check the warranty and customer support offered by the manufacturer. A good warranty and responsive customer support can provide peace of mind and help you get the most out of your generator.

Champion Power Equipment 200966 Features & Benefits

Champion 200966 Features

Power & Run Time

With the ability to produce 4375 starting watts and 3500 running watts on gasoline and 3950 starting watts and 3150 running watts on propane, this generator is capable of powering your essential appliances and devices during a power outage or outdoor adventure.

The generator can run for 14 hours at 50% load when using gasoline and 10.5 hours at 50% load when using a 20-pound propane tank. This means you can enjoy reliable power for an extended period of time without worrying about refueling.


Champion 200966 Oultets

Covered outlets provide an extra layer of protection against electrical shocks, especially when using power tools or appliances outdoors. This feature is incredibly important for ensuring my safety and the safety of those around me, and I appreciate the added protection it provides.

The generator is equipped with 120V 30A (TT-30R) RV outlet, a 120V 30A outlet (L5-30R), and two 120V 20A household outlets (5-20R).


While it’s true that it’s not the lightest generator on the market, at 123 pounds, it’s still manageable for most people to move around. Plus, it comes with a wheel kit and foldaway handle, making it even easier to transport and store. The generator has a compact design, with dimensions of 24.7 inches in length, 25 inches in width, and 22.2 inches in height.

Noise Level

Despite being a powerful generator, the noise level is surprisingly low. At only 68 dBA from 23 feet away, it’s only slightly louder than a vacuum cleaner, making it a great option for use in residential areas or campsites. This feature is incredibly important for me, as I don’t want to disturb my neighbors or fellow campers while I’m using my generator.

Dual Fuel capability

The Dual Fuel feature is incredibly convenient for me as an avid RV camper. It gives me the flexibility to choose between using propane or gasoline to power my generator, depending on what’s available or most cost-effective. This is a huge plus, especially when I’m camping in remote locations where propane may be more readily available. Plus, the patented fuel select dial allows for safe switching between fuel sources, making the transition easy and stress-free.

Electric Start

This generator with an electric start feature is a game-changer for me. No more struggling with a manual pull start, especially when it’s cold outside! With the convenient rocker switch, battery included, I can start up my generator with ease and get on with my day. This feature has saved me a lot of time and effort, and I love that I can quickly and easily power up my generator without any hassle.

Champion Power Equipment 200966 Generator Vs. the Competition

Gas & Run Time @50% Vs. Competition

The Champion 200966 generator stands out for its impressive run time, offering around 14 hours at a 50% load, which is higher than the average generator of its type and power range. If run time is a top priority for you, there are other generators available with even longer run times on a single full tank. For example, the Westinghouse iGen4500DF offers around 15 hours of run time in the same power range, making it a great option for those who require extended periods of use without refueling.

When considering run time, it’s important to also factor in fuel consumption, as run time is dependent on the fuel tank’s capacity. The Champion 200966 has an estimated fuel consumption of 0.34 GPH at a 50% load, which is average for generators in its wattage range.

However, if you’re looking for a generator with greater fuel efficiency, the Westinghouse iGen4500DF may be a good option to consider. It has a fuel consumption of just 0.23 GPH, making it one of the more efficient devices available in the same power output range.

Noise Vs. The Competition

If you prioritize low noise levels in a generator, it’s important to note that the Champion 200966 has a noise rating of 68 dBA, which falls on the noisier end of the spectrum compared to other generators with a similar running wattage.

However, it’s important to consider all features and benefits when choosing a generator that fits your needs. While the Westinghouse iGen4500DF may have a lower noise rating of only 52 dBA, it may not offer the same level of power or performance as the Champion 200966. Ultimately, it’s up to you to decide which features matter most for your specific use case.

Weight Vs. The Competition

At 123 pounds, the Champion 200966 generator is not the lightest option in the dual fuel category for generators that can produce 3000 to 4000 running watts. However, there are other generators in this power range that are lighter in weight. For example, the Genmax GM3500iAED is one of the champions in the same power range, with a dry weight of only 56.2 pounds.

Weight Vs. The Competition

The WEN GN400i generator is priced lower than the Champion 200966 generator. While both generators fall in the same power range, the WEN GN400i generator is more affordable, making it a good option for those on a tight budget.

However, it’s important to note that the WEN GN400i is a gas-only generator, whereas the Champion 200966 is a dual-fuel generator that offers the convenience of running on both gasoline and propane. So, if dual fuel capability is a must-have feature for you, the Champion 200966 might be worth the additional cost. Ultimately, your decision will depend on your specific needs and budget.

Final Thoughts

Overall, I highly recommend the Champion Power Equipment 200966 Generator to anyone looking for a versatile, reliable, and powerful generator. It’s packed with features that make it stand out in the market. This generator is a fantastic choice for anyone who loves to RV or spends time outdoors. What feature did you like the most?
