| Summary | 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. | The Yamaha EF7200D is a robust and economical generator, delivering a maximum output of 7200 watts and a rated output of 6000 watts. It features a durable 358cc OHV engine, providing up to 8 hours of continuous operation at full load. Designed for both home backup and professional use, it includes a wheel kit for portability and a digital hour meter for maintenance tracking. |
