The Champion 100900 generator has a rated noise of 53 decibels (dBA) when operating at a quarter load, which is just slightly louder than a conversation at home.

To give you some context, a noise level of 50-60 dBA is typically considered to be about as loud as a normal conversation. So, the Champion 100900 is relatively quiet and is suitable for use in quiet outdoor settings, such as campsites, tailgating events, or backyard gatherings, where you don’t want the noise to be too disruptive.

With all these features and more, the Champion 100900 generator is sure to be a great addition to your camping setup.


The Champion 100900 is a high-quality and reliable inverter generator that can run on both gasoline and propane. It is suitable for a variety of applications, such as powering RVs, outdoor events, and home backup power.

In terms of price, $600 is a mid-range price point for inverter generators of this size and quality. There are certainly cheaper options on the market, but they may not offer the same level of performance or features as the Champion 100900. On the other hand, there are also more expensive options that may have additional features or higher power output.

If you require a reliable and versatile inverter generator with a mid-range price point, the Champion 100900 may be a good choice. However, if you have a tight budget or require a generator with higher power output, you may need to consider other options.

Design and Features of Champion 100900

Champion 100900 Features

Power and Run Time

The Champion 100900 generator is powered by a 79 cc OHV 4-stroke engine. This engine provides up to 2,000 watts of peak power and 1,700 running watts on gasoline, or 1,0530 running watts on propane.

The engine runs smooth and quiet with low vibration levels and is designed for easy starting in any weather condition.

The Champion 100900 has a run time of up to 11.5 hours on gasoline, and up to 34 hours on propane, at 25% load capacity on a 1.1 gasoline tank and full propane tank of about 20 lbs., respectively. This makes it ideal for long camping trips or emergency situations.

With its smart economy mode, this generator can save fuel when not in use, helping you save money in the long run. All these features make the Champion 100900 generator an ideal choice for anyone looking for a high-quality power source.

Dual Fuel Technology

The Champion 100900 inverter generator features dual fuel allowing both gasoline (1.1 gals) and propane (20-lb propane tank). This means that you have the flexibility to choose the fuel source that is most convenient for your situation.

The dual fuel technology allows you to choose the most cost-effective and available fuel option in your area. For example, if you are camping in a remote area where gasoline is not readily available, you can use propane instead.

Also, dual-fuel inverter generators generally have better performance than single-fuel generators. For example, propane burns cleaner and produces less carbon buildup in the engine, which can lead to a longer lifespan and better performance.

Quiet Operation

The Champion 100900 inverter generator is designed to operate quietly, with noise levels as low as 53 dBA from 23 feet. This is considered an ultra-quiet level of operation, making it ideal for use in residential areas, camping sites, or any other location where noise needs to be kept to a minimum.

The quiet operation of this generator is achieved through several features, including the use of inverter technology, a specially designed muffler, and a low-tone muffler that reduces the noise levels.

Inverter technology allows the generator to produce clean and stable power that is safe for sensitive electronics while also minimizing noise levels. The muffler is designed to reduce engine noise by trapping and dissipating the sound waves,

Lightweight Design

The Champion 100900 is a lightweight portable inverter generator, weighing 39 pounds. With its lightweight design, it can be easily transported and stored without taking up a lot of space. Despite its lightweight design, this generator packs a punch with a maximum power output of 2000 watts and a rated power output of 1700 watts.

This Champion Power Equipment model generator is perfect for camping trips, tailgating events, construction sites, and more – it’s an ideal source of power when you’re on the go! With its compact design and lift handle, this generator can easily fit in the trunk of your car or be carried by hand.

Parallel Ready

The Champion 100900 generator is parallel-ready, which means it can be connected in parallel with another compatible Champion inverter generator using a parallel kit.

To connect the Champion 100900 generator with another Champion 2000-watt inverter, you will need to purchase a parallel kit. The parallel kit includes two 30 Amp RV outlets that allow you to connect the two generators together. You will also need to make sure the two generators are compatible and have the same voltage. Once connected, the two generators will provide up to 30 amps of power combined giving you more power options when running multiple appliances or tools at once.

Clean Electricity

The Champion 100900 dual-fuel inverter generator is designed to provide clean and reliable electricity with a total harmonic distortion (THD) of less than 3%. This means that the power output from this generator is very stable and suitable for powering electronics, such as laptops, smartphones, and other small appliances, without the risk of damaging them.

In contrast, generators with higher THD levels can produce inconsistent power that can damage or degrade the performance of sensitive electronics. This is why it’s important to choose a generator with a low THD level if you plan on powering these types of devices.

Overall, the Champion 100900 inverter generator is a great choice for anyone looking for a portable and reliable power source that can provide clean electricity with a low THD level.

Auto Low-oil Shut Off

The Champion 100900 generator is designed with safety in mind and features a low oil shut-off sensor. This sensor is a safety feature that helps prevent damage to the engine by shutting off the generator automatically if the oil level drops too low.

When the oil level in the generator’s engine drops below a safe level, the low oil shut-off sensor will detect the drop in oil pressure and trigger the sensor to shut off the engine. This is an important safety feature that ensures the generator’s engine is protected and extends the life of the generator, making it a reliable and safe power source for your needs.

Overload Protection

The Champion 100900 generator is designed with several safety features including overload protection and an automatic low oil shut-off. These features work together to protect the generator’s engine and the devices being powered from potential damage.

The overload protection feature, which is implemented through a circuit breaker, helps prevent damage to the generator’s electrical components by cutting off power to the generator in the event of an overload. This can happen when too many devices are connected to the generator at the same time, or when a device requires more power than the generator can supply. By cutting off power, the circuit breaker protects the generator and the devices being powered from damage.

Cold Start Technology

The e Champion 100900 inverter generator is designed with Cold Start Technology, which ensures a quick and reliable start in cold weather conditions.

Cold weather can make starting a generator more difficult due to the thickening of the engine oil and other factors. With Cold Start Technology, the Champion 100900 inverter generator is designed to overcome these challenges and provide a quick and easy start, even in cold temperatures.

The Cold Start Technology feature includes a special design of the carburetor and an automatic choke system that work together to provide the engine with the right amount of fuel and air mixture needed for a quick and reliable start. The choke automatically adjusts to the optimal position for the ambient temperature, and the carburetor is designed to provide the right amount of fuel to the engine, even in cold weather.

Overall, the Cold Start Technology in the Champion 100900 inverter generator is a valuable feature for those who need a generator that can reliably start and operate in cold weather conditions. This feature can help ensure that the generator is always ready to go when you need it, regardless of the temperature outside.
