10 Best Gen Generators 2026 in the United States

The GENMAX Portable Generator GM9000iED is a strong choice if you need a reliable power source for home backup, job sites, or outdoor activities like camping. Its 9000 peak watts and 7600 running watts provide ample power for most household or work needs. A key strength is its dual fuel capability, running on either gas or propane, which offers flexibility depending on your fuel availability and preferences.

Portability is fairly well addressed with sturdy wheels and a steel handle, though at 280 pounds, it's on the heavier side, so it’s more portable than lightweight but still manageable with some effort. The electric start and remote key fob add convenience, making it easier to operate than pull-start models. One of the standout features is the quiet operation—at 62 decibels under moderate load, it’s quieter than many generators, which is great for neighborhood or camping use. The low idle mode helps extend run time and save fuel, and the 6.9-gallon tank supports long usage periods.

Safety-wise, the built-in carbon monoxide detector is a valuable addition that automatically shuts off the generator if unsafe gas levels are detected. The unit also supports parallel connection, allowing you to link two generators for double power, though the parallel kit is sold separately. The generator’s weight can be a challenge if you need to move it around frequently. Also, while it has 5 outlets and supports both 120V and 240V outputs, users looking for more extensive connectivity options might find it somewhat limited.

The DuroMax XP12000HX is a versatile 12,000-watt generator that can power your entire home during outages. It runs on both gasoline and propane, offering flexibility and fuel efficiency. The 457cc OHV engine with all copper windings ensures durability. With a variety of outlets, including a transfer switch-ready 50 amp outlet, it suits both residential and commercial needs.

The push-button electric start and front-facing interface make it user-friendly. However, at 222 pounds, it's quite heavy, though the included wheel and handle kit aid mobility. Additionally, it features CO Alert for safety. The DuroMax XP12000HX is ideal for those needing reliable, robust backup power for homes or RVs.

Its dual-fuel capability and comprehensive outlet options add to its appeal, though its weight could be a drawback.
