Real-world differences
The output is nearly a tie
Gasoline running output differs by only 50 watts. On propane the DuroMax publishes slightly more running output, even though Champion has the higher peak label.
Champion is the known light-carry benchmark
At 43.2 pounds, the 201323 is easy to classify: it is genuinely hand-carried. That matters more than a small wattage difference for campers.
DuroMax's remote-start listing is unusual in this size
Remote start is rare on very small inverters. If that feature matters, verify the exact XP2300iH package and key-fob inclusion before buying.
Who should buy which?
Buy the Champion if…
You want the simplest lightweight dual-fuel camping generator with a well-documented sound figure and strong portability.
Buy the DuroMax if…
Remote-start capability and long propane runtime are more valuable than the small gasoline-output advantage of the Champion.

Price, parts, and ownership cost
Purchase price is only one part of the decision. Budget for the oil and service parts specified in the manual, a weather/storage cover, correctly rated cords, fuel containers or propane equipment, and any model-specific parallel or RV hardware you actually need. Electric- and remote-start models also add a battery that has to remain healthy during storage. For emergency use, parts availability and local service can matter more than saving a small amount at checkout.
When comparing marketplace listings, match the exact model number rather than only the wattage in the title. Generator families often contain several revisions with different starting systems, CO-shutoff hardware, outlet panels, CARB status, included propane hoses, or parallel-kit compatibility. A lower price is not a bargain if the listing is an older revision that lacks a feature your plan depends on. For used generators, ask about hours, storage fuel, oil-service history, load testing, and whether the inverter or voltage-regulation system has been verified under load.
Generator safety is not optional
Portable generators are combustion engines. The U.S. Consumer Product Safety Commission says to operate them outside only, at least 20 feet from the home, with exhaust pointed away from the home and other occupied buildings. A garage, shed, carport, porch, basement, crawlspace, or partly enclosed area is not made safe by opening doors or windows. Install and maintain carbon-monoxide alarms on every level of the home and outside sleeping areas.
For home circuits, do not improvise a connection and never backfeed a house through a receptacle. A transfer switch or properly approved interlock/inlet arrangement should be selected and installed in accordance with the generator manual, electrical code, utility requirements, and qualified professional guidance. For rain or snow, follow the manufacturer's weather instructions rather than moving a running unit into an enclosure.
Output ratings also change by fuel. Propane and natural gas commonly produce less power than gasoline, so size the system around the fuel you actually expect to use. Verify the appliance nameplate, motor starting behavior, voltage, receptacle type, and generator manual before purchase.
FAQ
Can either run a 13,500 BTU RV AC?
They are generally too small for a typical RV air conditioner without very favorable startup characteristics and careful load management. A 3,000–4,500W class generator is the safer shopping target.
Which makes more power on propane?
The referenced Champion publishes 1,665 running watts on propane; DuroMax publishes 1,700.
Are these good for refrigerators?
Yes for many refrigerator/freezer and electronics loads, but always account for compressor startup and other simultaneous loads.
