Portable-generator shopping starts with a load plan, not the largest wattage printed on a box. This guide compares four exact configurations using current manufacturer documentation. ToolShed Tested did not physically test these generators.
Quick answer
- Best dual-fuel inverter: Champion 200988
- Best lower-cost open-frame option: Westinghouse WGen3600v
- Best higher-output dual-fuel option:DuroMax XP5500EH
- Best compact inverter:Pulsar G2319N
The Champion 200988 is an inverter generator, not a conventional open-frame model. The Westinghouse and DuroMax are open-frame generators. The Pulsar is a smaller inverter intended for a much narrower load plan.
Comparison table
Published running and starting watts are not interchangeable. Propane output can differ from gasoline output, and an appliance's startup demand can be much higher than its normal running demand.
1. Champion 200988: best dual-fuel inverter
Champion's manual identifies model 200988 as a 4,500-watt dual-fuel inverter generator. It lists 3,500 running watts on gasoline and 3,150 running watts on propane, with electric and manual starting.
Choose it when you want fuel flexibility and inverter operation for selected 120-volt loads. Skip it if your plan requires a 240-volt receptacle or more continuous output than the model provides.

2. Westinghouse WGen3600v: best lower-cost open-frame option
Westinghouse publishes 4,650 peak watts and 3,600 rated watts for the gasoline-powered WGen3600v. It includes a TT-30R RV receptacle and recoil start. The manufacturer lists the wheel and handle system as a separate kit, so confirm the exact package before checkout.
Choose it for a straightforward gasoline generator where rated output and RV connectivity matter. Skip it if dual fuel, inverter construction, or included wheels are requirements.

3. DuroMax XP5500EH: best higher-output dual-fuel pick
DuroMax publishes 5,500 peak and 4,500 running watts on gasoline, plus 5,225 peak and 4,275 running watts on propane. The XP5500EH supports 120/240-volt output, electric and recoil starting, and has a published dry weight of 124 pounds.
Choose it only after confirming the complete load calculation, receptacles, voltage, placement, and safe connection method. Higher output does not make it a whole-home solution by itself.

4. Pulsar G2319N: best compact inverter
Pulsar's manual lists 2,300 maximum watts, 1,800 rated watts, 120-volt output, a 1.18-gallon tank, USB output, and a 12-volt outlet. This is a compact portable-power model, not a substitute for the larger generators above.
Choose it for camping, tailgating, charging, or a small set of modest loads. Skip it when the load plan includes several motor-driven appliances or broad outage coverage.

Build the load plan before buying
- Record the running watts for every load you intend to use at the same time.
- Record the starting or surge requirement for motor-driven loads.
- Confirm the generator's rated output for the fuel you will actually use.
- Confirm voltage and receptacle compatibility.
- Decide which loads will run together and which must be staged.
- Follow the generator and appliance manuals. Do not rely on generic appliance-wattage estimates for a final decision.
Do not infer that a generator can run a particular air conditioner, well pump, medical device, or panel from its marketing wattage alone. Exact equipment nameplates, starting behavior, and connection requirements decide that.
Safety is part of the purchase decision
The U.S. Consumer Product Safety Commission says to use a portable generator outdoors only, at least 20 feet from the home, with exhaust directed away from the home and other occupied buildings. Install working carbon-monoxide alarms on every level and outside sleeping areas.
OSHA says not to connect a generator directly to a building electrical system unless a qualified electrician has installed an appropriate transfer switch. Keep the generator dry, use intact grounded cords rated for the intended load, shut the unit down before refueling, and follow the manufacturer manual.
Safety references: CPSC carbon-monoxide guidance and OSHA portable-generator safety.
Bottom line
The Champion 200988 is the broadest 120-volt fit here because it combines inverter operation, dual fuel, and electric start. The Westinghouse WGen3600v is the simpler open-frame value. The DuroMax XP5500EH offers the highest published running output and 120/240-volt capability. The Pulsar G2319N is the compact choice for a deliberately small load plan.
Verify the exact model, seller, package, fuel rating, receptacles, and current availability before buying. Never size or connect a generator from a roundup alone.
