As a result, the generator uses less fuel, produces less noise under lighter loads, and experiences less engine wear compared to many conventional portable generators.

With 5,200 starting watts and 3,900 running watts, the iQ5200 is capable of powering multiple household essentials at the same time. It can comfortably run appliances such as a refrigerator, freezer, lights, televisions, laptops, Wi-Fi routers, fans, and small kitchen appliances. It also has enough capacity for many RVs equipped with a 13,500 BTU air conditioner, although actual performance depends on the AC’s startup requirements and any additional appliances running simultaneously.

Because this is an inverter generator, it produces clean sine wave power with low total harmonic distortion (THD). That makes it safe for sensitive electronics, including:

• Laptops
• Desktop computers
• Smartphones and tablets
• Televisions
• Gaming consoles
• Medical devices such as CPAP machines
• Battery chargers
