Here's the quick tradeoff view — what this model does well, and where it may not fit.
The Champion Power Equipment 201537 is a tri-fuel generator delivering 6,500 running watts and 8,500 starting watts on gasoline, placing it firmly in the mid-to-large portable generator category. At this wattage level, the unit is capable of powering demanding household circuits during an outage, running multiple high-draw tools on a jobsite, or keeping an RV fully operational with air conditioning and appliances. The tri-fuel design adds a layer of versatility that single-fuel generators simply cannot match, allowing owners to switch between gasoline, propane, and natural gas depending on availability and preference.
What makes this model particularly interesting is that it pairs its robust conventional generator output with inverter technology, meaning the power it produces is cleaner and safer for sensitive electronics like laptops, televisions, and medical devices. Champion Power Equipment has built a reputation for producing reliable and affordable generators, and this unit appears to embody that philosophy by combining high output, fuel flexibility, and modern power conditioning in a single package.
The 201537 delivers its peak performance on gasoline, where it produces 6,500 running watts and 8,500 starting watts. When operating on propane, the running output drops to 5,850 watts, and on natural gas it settles at 5,265 running watts, though both alternative fuels still share the same 8,500-watt starting surge. This means that even on the lowest-output fuel, the generator can handle substantial loads, though users planning to run near-capacity equipment should factor in the reduced output on propane or natural gas.
Runtime on gasoline at 25% load reaches 13 hours, which translates to a comfortable overnight run or a full day of light usage before refueling is necessary. On propane at the same 25% load, runtime comes in at 12 hours, only a marginal difference. At 64 dBA, the noise output is comparable to a normal conversation at close range. This means that while the generator is not whisper-quiet, placing it 20 to 30 feet from living or working areas should keep the sound at a tolerable level. Because this is an inverter generator, it produces clean power that is safe for sensitive electronics, making it a strong choice for those who need to charge phones, run computers, or power home entertainment systems without worrying about voltage irregularities.
The outlet panel on the 201537 is both versatile and well-suited to a range of applications. Four NEMA 5-20R outlets provide standard 120-volt, 20-amp household connections, which means users can plug in everyday devices, power tools, and appliances without adapters. The single NEMA 14-50R outlet delivers 120/240-volt power at 50 amps, opening the door to heavy-duty applications such as connecting to a home transfer switch or powering large equipment that requires 240-volt service.
For RV owners, the dedicated TT-30R outlet provides a 120-volt, 30-amp connection that matches the standard RV shore power plug, making hookup at a campsite straightforward and hassle-free. Rounding out the panel is a single 12-volt DC outlet, useful for trickle-charging batteries or powering DC accessories directly.
At 132.3 pounds, the Champion 201537 is a heavy machine that demands some planning when it comes to movement and storage. This is not a generator that most people will want to lift or carry unassisted, and loading it into a truck bed or moving it across uneven ground will be significantly easier with the help of a second person or an integrated wheel kit. The substantial weight is a trade-off for the high power output and tri-fuel capability packed into this unit, so prospective buyers should consider where they plan to store and stage the generator and ensure they have a means of transporting it without strain.
The starting system on the 201537 is one of its standout conveniences, offering three distinct methods: a traditional recoil pull start, an electric push-button start, and a wireless remote start. The remote start option is a genuine luxury, allowing users to fire up the generator from a distance without walking outside in harsh weather or leaving the comfort of their RV. This trio of starting methods ensures that owners always have a backup way to get the unit running, regardless of conditions.
The generator is RV ready, confirming that it can connect directly to recreational vehicles without requiring additional adapters or modifications. This designation, paired with the TT-30R outlet, makes it a practical travel companion for RV enthusiasts who need reliable power on the road.

These are estimates using typical wattage assumptions. Real appliances vary. Startup surges can be 2–6× the running wattage for motor-driven loads. 240V loads require a 120/240V generator and proper connection. Use a transfer switch or interlock kit; never backfeed a panel.
