| Summary | The Briggs & Stratton 30814 P4500 PowerSmart is a 3700-watt inverter generator built for users who need reliable backup power without the noise of traditional models. At 60 decibels, it runs quiet enough for residential neighborhoods and campgrounds, making it suitable for homeowners managing outages, campers extending trips, and outdoor enthusiasts who cannot tolerate generator noise. The 4500-watt peak output handles startup surges for larger appliances like air conditioning units or power tools, while the 3700-watt running capacity sustains continuous operation. With a 3.5-gallon fuel tank and 16-hour runtime at 25% load, users can power essential devices through a full night or longer without refueling. The inverter technology produces only 3% THD, which means laptops, smartphones, and other sensitive electronics charge safely without risk of voltage spikes or damage. | The NorthStar c15000s is a commercial-grade portable generator powered by a Honda GX690 OHV engine, delivering 15,000 surge watts and 13,500 rated watts. It features Quiet Armor Technology for reduced noise, a built-in battery charger/maintainer, and carbon monoxide detection with automatic shutdown for enhanced safety. |
