Generator Type: Champion 100519 is a powerful digital hybrid open-frame inverter generator. It is different from a 5000-watt conventional generator in terms of weight, sound, and size. RV travelers, homeowners, food van owners, tailgaters, campers, or even professionals can use this generator to power their appliances, electronics, or tools.

Portability: Its efficient mechanical design decreases its weight.

It is 20% lighter (121 lbs.) than a traditional 5000-watt generator, and its dimensions are 26.6” (L) x 25.6” (W) x 23.7” (H).

Champion 100519 comes with 8” never-flat wheels and a folding handle for easy mobility. You will find it difficult to lift it manually, but once it hits the ground, it will become easy to handle.

Starting Mechanism: A traditional pull-start mechanism featuring cold start technology ensures quick and easy starts in minus temperatures.

Output Power: Champion 100519 can produce 6250 starting watts and 5000 running watts, thanks to its 301cc, 4-stroke OHV engine.

This output power is quite enough to run your essentials at home, camping, or a worksite.

Champion 100519 delivers clean power with only 3% THD (Total Harmonic Distortion). It means you can also connect your sensitive electronics along with appliances and tools.

Tank Size and Runtime: A 4-gallon steel tank allows the engine to run up to 12.5 hours at a quarter load. It uses up to 0.32 gallons of gasoline per hour.

Economy Mode: An economy mode helps the engine change its rotating speed and fuel consumption according to the amount of load applied. This will save fuel, provide quieter operation, and increase the engine’s life.

Operational Sound: This Champion 100519 inverter is 50% quieter than a traditional 5000-watt portable generator. It operates at 69 dBA.

Control Panel: Its control panel has four GFCI-protected 120 Volt 20 Ampere (5-20R) outlets, one transfer switch ready 120/240 Volt 30 Ampere (L14-30R) outlet, and one 12 Volt 8 Ampere DC (cigarette lighter style)outlet with a dual USB adapter. All the power receptacles are rubber covered for protection.

GFCI (Ground Fault Circuit Interrupter) outlets provide ultimate protection against electrical shocks.

Also, Champion 100519 includes an intelligauge that helps monitor voltage, frequency, and lifetime operating hours.

Other than this, there are three light indicators that turn on when the oil levels are insufficient, the generator is ready to go, and the generator is overloaded.

Safety: Overload protection and low-oil shutoff are the two most common safety features.

Overload protection shuts off the engine when users apply additional electrical load to the generator. Low-oil shutoff also stops the engine in case of insufficient oil levels.

Warranty: It features a limited 3-year warranty with free lifetime technical support.

Emissions: Champion 100519 is easy to ship to any American state as it is certified and tested by both EPA (Environmental Protection Agency) and CARB (California Air Resources Board) agencies.

My Opinion:

Pros: Champion 100519 is a quality inverter generator. It is easy to set up and move. It produces clean and higher output power with the help of a powerful engine. It is lighter, quieter, built to last, and has GFCI outlets. Also, Champion 100519 includes a 3-year limited warranty.

Cons: Its fuel tank capacity is relatively low. Also, it doesn’t have an electric start system.


What is its oil capacity? What type of oil Champion recommends for this model?

It has an oil capacity of 1.2 quarts. Champion recommends 10W-30 automotive oil for this model, but you can switch to synthetic oils at the time of the first oil change.

What is the function of the choke?

Choke helps start cold engines. It allows more fuel to pass to the carburetor as compared to air. This rich fuel mixture helps the engine to start easily at low temperatures. But once the engine starts, turn off the choke switch to allow the engine to run on a fair mixture of air and gasoline.

Can I operate Champion 100519 at high altitudes?

Both the engine power and generator output get affected by about 3% for every 1000 feet. You can use this Champion 100519 at high altitudes but to deal with high altitude issues, never forget to install a high altitude carburetor main jet.
