Summary
The Westinghouse iGen5000 is a gas-powered portable inverter generator delivering 5,000 peak watts and 3,900 running watts. It features a compact design with a telescoping handle and never-flat wheels for easy portability, making it suitable for recreational activities and emergency backup power.
The Aceup Energy AI4500 is a 3,600-watt inverter generator built around a 223cc 4-stroke OHV engine. It produces 3,600 running watts and 4,500 peak watts, making it suitable for home backup of essentials, jobsite tools with moderate surge needs, and applications where clean power matters. As an inverter model, it delivers stable electricity to sensitive electronics like laptops, chargers, and networking gear while handling traditional household loads and motor starts. The 2.65-gallon fuel tank and 10-hour runtime at 25 percent load support overnight run windows for light to moderate demand. Parallel capability lets users connect two units later to increase total output without replacing the generator entirely.
