Champion 3500 Watt Generator Review – Dual Fuel Power for RVs and Homes

We spent three full days testing the Champion 3500-Watt Dual Fuel Generator to see how it performs in terms of power output, runtime, noise, and overall usability. Designed with both RV owners and homeowners in mind, this unit promises flexibility and solid performance, especially with its RV-ready outlet and dual fuel capability.
Let’s dive into the details and see whether this generator lives up to its claims.

Unboxing and First Impressions
The generator arrived well-packaged, with foam and cardboard offering strong protection during transit. Inside the box, we found a user manual, propane hose, engine oil, and an oil funnel. The build feels sturdy, and the yellow-black color scheme is visually appealing.
One notable drawback is the absence of a wheel kit, which would make transportation much easier. You can buy it separately, but we feel it should’ve been included by default.
Design and Build Quality
The overall design is rugged and user-friendly, featuring a clean control panel layout. While compact and fairly lightweight for a dual fuel unit, the lack of built-in wheels is a disadvantage, particularly for users who plan to move it frequently.
Control Panel & Outlet Options
The control panel includes:
- 2x 120V 20A AC outlets
- 1x 120V 30A RV-ready outlet
- 1x 120V 30A locking outlet
- Circuit breakers
- 3-mode intelligauge (voltage, frequency, runtime)
- Engine ON/OFF switch
- Fuel selector switch
- LPG inlet
Fuel Tank, Runtime & Fuel Flexibility
The Champion 3500-Watt Generator comes with a 3.4-gallon gasoline tank and the ability to connect to a propane tank for extended runtime.
During our tests:
- Gasoline: 9–10 hours @ 50% load
- Gasoline: Up to 12.5 hours @ 25% load
- Propane: Varies depending on tank size, but generally longer due to larger volume availability
While newer models may offer larger fuel tanks, the dual-fuel design here allows for flexible operation, especially in extended outages or during travel.
Load Capacity Test Results
Powered by a 224cc 4-stroke engine, this unit delivers:
- Gasoline: 4375 surge watts / 3500 running watts
- Propane: 3950 surge watts / 3150 running watts
We tested it with several high-demand appliances:
Appliance | Surge (W) | Running (W) |
15,000 BTU RV A/C | 3500 | 1500 |
Coffee Maker | 1740 | 1740 |
½ HP Air Compressor | 1600 | 975 |
½ HP Water Pump | 1000 | 2100 |
Sump Pump (½ HP) | 1050 | 2150 |
Space Heater | 1800 | 1800 |
Lighting + TV | – | 1800 |
Every device listed above ran smoothly on both gasoline and propane. This generator handles a standard RV or home setup with ease but isn’t designed for running heavy-duty appliances all at once.
Noise Test
The manufacturer rates this unit at 68 dB from 23 feet, but we found that under a 75% load, it actually ranges between 71–74 dB at 25 feet.
Tip: Position the generator 40–50 feet away from your RV or home for quieter operation.
Parallel Capability
This model is not parallel-compatible. If you need more power or plan to run multiple large appliances simultaneously, consider a generator with parallel capability or a higher wattage unit.
Maintenance & Warranty
Routine maintenance includes oil and air filter changes, seasonal storage prep, and carburetor cleaning. Champion backs this generator with a 3-year limited warranty and lifetime technical support, with service centers located across the U.S.
Environmental Safety
Certified by both EPA and CARB, this generator meets strict emission standards, making it a safe choice for both the user and the environment.

- Compact and portable (for its category)
- Strong and consistent voltage output
- Dual fuel compatibility
- RV-ready with 30A outlet
- Impressive runtime

Who Should Buy It?
The Champion 3500-Watt Dual Fuel Generator is a great choice for:
