Summary
The Briggs & Stratton 30758 P2400 PowerSmart is an 1800-watt inverter generator built for users who need portable, clean power without the weight penalty. At 51 pounds, this unit sits at the intersection of serious capacity and genuine portability. It runs household essentials like refrigerators, power tools, and laptops simultaneously, but cannot power an entire home or heavy-duty job site equipment. The 79 cc OHV engine produces 2400 starting watts to handle motor inrush, then settles to 1800 running watts for sustained operation. This inverter's sub-3% THD output protects sensitive electronics from voltage spikes that damage laptops, phones, and medical devices. The gasoline fuel type means refueling at any gas station, and the 1-gallon tank with 8-hour runtime at 25% load creates a predictable refueling cycle for day-long use. Three-year warranty coverage backs the entire package, making this a low-risk entry point for homeowners, campers, and emergency preparedness planners.
The Powermate PM4500 is a 4500-watt portable generator featuring COsense® Technology for carbon monoxide protection, a Generac® 224CC OHV Engine, and a 19-hour run time at 25% load.
