Champion 4500W Dual Fuel Open Frame Inverter Generator


Description

The Champion 4500W Dual Fuel Open Frame Inverter Generator is built for campers, RV travelers, tailgaters, and homeowners who need reliable backup power without the bulk. Running on either gasoline or propane, it delivers 4500 starting watts and up to 3650 running watts on gas, giving you the flexibility to use whatever fuel is available. Champion's Quiet Technology keeps noise at just 64 dB(A) - up to 50% quieter than equally rated traditional generators - while the efficient open frame design comes in 20% lighter than comparable units.

Powered by a 224cc Champion engine with electric push-button start, this inverter produces clean power safe for sensitive electronics and features the CO Shield® carbon monoxide auto-shutoff system for added safety. Whether you're powering your RV, running tools at a job site, or keeping the essentials on during a storm, the Champion 4500W Dual Fuel Inverter delivers dependable performance with the peace of mind of a 3-year limited warranty and free lifetime technical support.

Manuals & Guides

FAQ

Can I run this generator indoors or in my garage?

No. Like all generators, the Champion 4500W Dual Fuel Inverter must ALWAYS be used outdoors, far away from occupied buildings, with the engine exhaust pointed away from people and structures. Even with the CO Shield auto-shutoff system, generators produce carbon monoxide - a colorless, odorless, poisonous gas. CO Shield is a safety backup, not a substitute for safe operation. Always run this unit outdoors with plenty of ventilation.

What is the difference between gasoline and propane performance?

On gasoline, the generator delivers 4500 starting watts and 3650 running watts with a 22-hour runtime at 25% load on a full 4.02-gallon tank. On propane, it delivers 4500 starting watts and 3285 running watts with a 21-hour runtime at 25% load using a 20-lb tank. Gasoline provides slightly higher running wattage, while propane offers the convenience of longer storage life and easy connection to a standard BBQ-style tank.

Is the parallel kit included?

No, the parallel kit is sold separately (Champion Model #100319 - 50A ParaLINK Parallel Kit). With the kit, you can connect two compatible Champion inverters together to double your power output - useful for larger RVs or when powering more equipment simultaneously.

What outlets does this generator have?

The generator includes a 120V 30A RV outlet (TT-30R), a 120V 20A duplex household outlet (5-20R), and a 12V regulated automotive-style outlet. All outlets are covered for weather protection. Note there are no GFCI receptacles on this model.

Does this generator require assembly?

Minimal assembly is required - you will need to add the engine oil (included) before first use. The unit ships mostly assembled. Refer to the included Quick Start Guide or Operator's Manual for full setup instructions before first startup.

How is this generator shipped?

This generator ships via standard ground freight due to its size and weight (92.6 lb.). Please email us at service@omahasportsandgames.com for a specific delivery ETA and any questions about the delivery process.
