Let’s investigate its features in detail now!

Review of the Champion 100402 2000-Watt Dual Fuel Portable Inverter Generator

Dual Fuel Machine

It is a dual fuel machine. You can run it on gasoline and propane. When you have the freedom to run your machine on two different fuel types, you won’t run out of options for powering your appliances. You can use gasoline on your Champion 100402 2000-watt inverter for routine power outages runs and propane when there is an emergency or your gasoline has run out. 

Comparing both fuel types reveals that gasoline is more powerful than propane and delivers 10-20% more starting and running watts. Propane gives higher runtime in smaller machines and less in bigger machines. In addition, it burns safe and doesn’t produce high levels of CO2 like gasoline. Moreover, the risks of spillage or fire are lower.  In contrast, gasoline has a shorter shelf life than propane, as propane can last for years. 

Power Output and Usability

The inverter delivers 2000 starting and 1600 running watts on gasoline. The peak output on propane is 1800 watts, and the rated output is 1440 watts. The power output is ideal for running lights, TV, computer, internet modems, phone and laptop chargers, and other appliances falling under its rated power. The inverter can support multiple phones and chargers when you are outdoors or on RV trips. You can also power a portable fridge, ice maker, shaver, and many other appliances.

This inverter is commonly used for tailgates, pool parties, BBQ events, game nights, and other casual gatherings due to its low noise level when running. Many people also use this machine to power smaller tools when completing DIY projects. However, it is not recommended for worksites or commercial use as it can only support 1-2 power tools.

The starting amps for gasoline at 120 volts are 16.7, and running amps are 13.3, whereas on propane, starting and running amps are 15 and 12, respectively.

Tank Capacity and Runtime

The inverter comes with a 1.1-gallon tank capacity, and the suggested propane tank is 20 pounds. One full gas tank or 20-pound propane tank can run for 11 hours and 34 hours, respectively, at 25% load. On 50% load, the runtime will be 5-6 hours on gasoline and 16-17 hours on propane. Let us break down this for you in simple terms.

If the load applied on your machine while running on gasoline is 800 watts, then one full gas tank will run for 5-6 hours, and if the load applied while using propane as fuel is 700 watts, then the 2000-watt inverter will run for approximately 16 hours.

Please note that the runtime, in theory, is different from the runtime in actual use. The runtime is measured by several factors, including your generator’s health, appliances’ age, quality of fuel, and load applied to the machine. Champion’s 100402 2000-watt inverter comes with an eco-mode that adjusts the engine speed according to the load applied on the machine. This ensures that the engine works less when the load is low,  resulting in longer engine life, higher runtimes, and quiet operation. Moreover, it is recommended to add appliances one by one to your machine and turn off the machines/appliances once they are no longer needed.

Engine Specifications

Champion’s 2000-watt inverter uses an 80cc 4-stroke variable speed dual-fuel Champion engine. The engine is good enough to deliver a steady stream of output with less than 3% THD. As a result, you will never notice any fluctuation or feel that your appliances are underpowered.

The recommended engine oil type is 10W-30, and you need 0.4 quarts of oil for this machine. Please note that engine oil for first-time use is not included in the original purchase. Also, the engine is recoil starting and doesn’t feature an electric or remote start.  

Moreover, this machine’s engine is covered inside by shock-absorbing parts, making it slightly difficult to access the engine and change oil. However, this feature also makes it less noisy and reduces vibration and rattling.

Control Panel and Outlets

The inverter comes with an advanced and interactive control panel. For example, the digital power panel includes a low oil indicator, power output monitor, fuel level, total runtime, fuel life, receptacle status, economy mode indicator, and maintenance status.

The bar-style digital indicator for output and fuel makes this machine extremely user-friendly. Its control panel also shows the remaining runtime to help you evaluate when you need to refuel the machine. The control panel also features outlets, breakers, grounding ports, and parallel connectivity ports.

Outlets consist of two 120V 20A duplex (5-20R) and one 12V DC automotive-style outlet. The 120V outlet is best for running household appliances or appliances on the go, and the 12V DC automotive-style outlet works best for portable refrigerators and other appliances. Please note that the machine doesn’t come with a USB outlet. Therefore, it limits its ability to connect USB-style cables. You will need a USB-to-AC adapter to connect USB cables to the inverter.

It is also worth mentioning that outlets are not GFCI protected and don’t come with rubber covers. Moreover, the circuit breakers are also not covered.

Noise Level

Inverters are primarily used for outdoor gatherings and events like tailgates, BBQ parties, game nights, and campsites. Hence, they must not be very noisy. Champion’s 100402 2000-watt inverter generator runs at 53 dBA, measured at a distance of 23 feet.

The noise level is in line with other inverters in this category; therefore, it will not bother you much. The noise of this inverter is not more than someone having a conversation near you. With Champion’s inverter, you won’t need to worry about noise reduction boxes.

Dimensions and Weight

The machine measures 20.5 x 12.6 x 16.9 inches and weighs only 46.5 pounds. One healthy individual can lift the machine and move around with it.


Another important feature that you need to consider before buying an inverter is portability. Lightweight machines like Champion’s 100402 2000-watt inverter generator don’t need wheels. Instead, they need an ergonomic and comfortable carry handle. The handle on this machine makes it easy to lift and move with the machine.

Warranty and Certifications

All champion generators are covered with a 3-year residential and 2-year commercial warranty. The warranty agreement includes faults and workmanship for mechanical and electrical parts in the machine. Please note that a fair usage policy applies to the warranty agreement. It is invalid when excessive use has damaged a part or whole machine. The warranty agreement is also invalid against acts of God and the use of non-Champion replacement parts. Any transportation charges incurred against sending/receiving your machine for warranty claims will be paid by the owner of the machine.

The inverter is EPA-approved and CARB-compliant. You can use it all over the US (50 states). Please note that it is not PGMA G300-2018 compliant.
