Summary
The Firman W02981 is a 2,900-watt inverter generator built around a 171cc Max-Pro Series OHV 4-stroke engine with a cast iron sleeve. This wattage runs a refrigerator, microwave, and several household circuits simultaneously, or powers a small RV setup with air conditioning. The 1.8-gallon fuel tank delivers 10 hours of runtime at 25% load, meaning light-duty operation stretches a single tank across a full workday or camping trip. At 58 decibels, it operates quietly enough for residential neighborhoods and campgrounds. The 3% THD output protects laptops, phones, and sensitive electronics from voltage spikes that damage circuits. Weighing 84 pounds with a wheel kit included, it sits at the threshold between portable and stationary, requiring two hands or a dolly for regular movement.
The WEN 56360iX is a 3600-watt RV-ready portable inverter generator designed for clean and quiet power, featuring a 149cc engine, fuel shutoff, and a CO shutdown sensor.
