Generac 3600W 49ST Portable Generator

The Generac GP3600 (Model 7721) is a reliable and efficient 3,600‑watt portable generator designed to power tools, equipment, and essential appliances during home projects, outdoor events, and emergency outages. Fueled by generac's robust 212cc OHV engine, it delivers 3,600 running watts and 4,500 starting watts, ensuring strong and consistent power for inductive loads like pumps, saws, and refrigerators.

Built with inverter technology, the iQ5200 delivers low total harmonic distortion, making it safe for powering sensitive electronics such as laptops, phones, and medical devices. The fully enclosed housing not only protects the internal components but also helps reduce noise levels, allowing for quieter operation in residential or recreational environments.

Featuring PowerRush™ advanced technology, the GP3600 instantly boosts its output by over 40% to accommodate heavy starting requirements—perfect for devices with high initial draw. It also includes a sizable 3.7-gallon steel fuel tank with integrated fuel gauge, supporting up to approximately 9.3 hours of continuous operation at half load, making it ideal for longer jobs or storm preparedness.

Safety and durability come standard with Generac’s COsense® system, which actively monitors carbon monoxide levels and automatically shuts down the unit if unsafe gas levels are detected. A low-oil shutdown protects the engine from damage, while the hardened steel tube cradle and heavy-duty never-flat wheels with a fold-down handle provide ruggedness and portability. Despite its tough build, it remains compact enough for easy storage.

The control panel offers two 120 V 20 A outlets and one 120 V 30 A twist-lock outlet, all protected by circuit breakers and conveniently covered. An hour meter tracks usage for maintenance, and simple recoil-pull start makes it user-friendly. Together, these features create a high-performing, safe, and dependable generator suitable for homeowners, DIYers, and professionals.
