10 Best Natural Gas Home Generators 2025 in the United States

The Generac 7172 10kW Air Cooled Guardian Series Home Standby Generator is a robust option for those seeking reliable home power backup. With a strong power output of 10,000 watts, it is capable of handling essential household needs during outages. One of its standout features is the 100-amp automatic transfer switch, which ensures seamless switching and comprehensive protection for up to 16 circuits.

The generator operates on natural gas or LP gas, offering flexibility in fuel options. The Mobile Link Wi-Fi connectivity allows for remote monitoring and real-time updates, which is highly convenient for users who travel or want peace of mind when away from home. The unit is designed for easy installation by a licensed electrician and is made with durable materials, including an aluminum enclosure and a purpose-built G-Force engine, which promises reduced maintenance and high reliability.

Additionally, the 5-year limited warranty provides long-term assurance of the generator’s durability and performance. At 338 pounds and a size of 48 x 25 x 29 inches, it is quite heavy and might not be easily portable. The noise level is mentioned as super quiet. This generator is a solid choice for residential use, offering versatile power, smart controls, and reliable operation, though its weight could be a potential drawback for some users.

The ERAYAK 4500W Dual-Fuel Portable Inverter Generator is a flexible and compact option ideal for home backup, RV trips, and outdoor activities. It delivers a solid power output of 3,500 running watts and 4,500 peak watts, enough to handle most household essentials and recreational appliances. One of its standout features is the dual-fuel capability, allowing you to switch between gasoline and propane easily. This extends run times—up to 16 hours on gasoline at a quarter load and more than 20 hours with propane—meaning longer use without frequent refueling. The generator also has an automatic fuel switch system that prevents unexpected shutdowns by prioritizing gasoline when propane runs out.

At just 58 decibels, it operates quietly, so it won’t disturb neighbors or your peace during camping or power outages. The compact size and relatively light weight (54 pounds) make it fairly portable for its power class. Safety features include a built-in carbon monoxide sensor that shuts the unit off if dangerous gas levels are detected, adding peace of mind for indoor-adjacent use. It’s equipped with convenient outlets including a 30A RV plug and USB ports for multiple devices.

A drawback is that the generator relies on a recoil start system, which might be less convenient than electric start models. While it includes a 3-year warranty and maintenance tools, like any generator it requires routine upkeep, especially if used frequently. Additionally, although it’s designed for propane and gasoline, natural gas (if from a fixed line) may need additional adapters or professional setup. This generator is suitable for anyone needing reliable, quiet, and versatile power for home backup or outdoor use, provided they are comfortable with manual starting and basic maintenance.

However, there are some considerations to keep in mind.
