| Summary | The Champion Power Equipment 201438 is a 10,000-watt Tri-Fuel portable generator equipped with CO Shield® technology, capable of operating on natural gas, propane, or gasoline. | The Cummins Onan P4500i is a 3700-watt inverter generator built for users who need reliable power without the noise penalty. Its 4500-watt peak capacity handles startup surges for air conditioners, power tools, and RV air conditioning units. The gasoline engine runs clean enough for sensitive electronics like laptops and phones, thanks to a 3 percent THD rating that protects against voltage spikes. This unit bridges the gap between portable camping generators and stationary backup power, making it useful for RV owners, homeowners facing extended outages, and contractors working near occupied spaces. |
