The DuroMax XP16000iH is a powerful dual-fuel generator capable of producing up to 16,000 starting watts and 13,000 running watts, making it well-suited for whole-home backup, job sites, or RV use. Its ability to run on both gasoline and propane offers great flexibility, especially if you want to switch fuels during longer outages or prefer propane for cleaner emissions. The generator features inverter technology, which means it provides stable power safe for sensitive electronics like laptops and TVs. Starting the unit is convenient thanks to the remote electric start, and the included battery tender helps keep it ready to go at all times.

It also has a digital control center with an easy-to-read display showing important information like run time and load. While the DuroMax XP16000iH is portable for its size, it weighs 368 pounds, so moving it around might require some effort or wheels. It has a large 10.5-gallon fuel tank.

An automatic low oil shutoff and EPA/CARB emissions compliance add safety and environmental friendliness. This generator is a robust, reliable power source capable of handling heavy loads, but if portability or quiet operation are top priorities, you might want to consider other options.

The generator features an electronic ignition system for easy and reliable starting, so you won’t have to worry about manual effort when power goes out. With its Wi-Fi connectivity, you can monitor its status remotely, giving you peace of mind even when you’re away.

Since it is designed to be a permanent home standby unit and weighs 338 pounds, it is not portable. However, it excels in durability and low maintenance thanks to its purpose-built engine. Installation requires a certified electrician, so it’s not a simple plug-and-play device but rather a solid investment for long-term home protection. This generator offers powerful, quiet, and efficient backup energy with smart features, ideal for keeping your home running smoothly during emergencies.

The Westinghouse Outdoor Power Equipment 14500 Peak Watt Tri-Fuel Home Backup Portable Generator is a versatile and robust option for those needing reliable backup power. With a peak power output of 14,500 watts and running power of 11,500 watts on gasoline, it is capable of handling substantial power needs. When using propane, it delivers 13,500 peak watts and 10,500 running watts, making it a strong choice for households and larger properties. For natural gas, it provides 12,000 peak watts and 9,500 running watts, offering flexibility depending on fuel availability.

The generator's run time is impressive, lasting up to 19 hours on a full 9.5-gallon gasoline tank and up to 7 hours on a standard 20 lb. propane tank, which ensures long periods of power during outages. The 230-pound weight and dimensions (27.2”L x 26.1”W x 26.5”H) make it quite hefty, which could be a drawback if frequent relocation is needed. However, its portability is somewhat mitigated by the built-in wheels and handles. Noise levels are typical for a generator of this size, but the presence of a muffler helps reduce the overall sound.

Fuel efficiency is decent, particularly with the tri-fuel capability, allowing users to choose the most cost-effective and available fuel source. The remote electric start feature enhances convenience, making it easy to operate without manual effort. Additional features like overload protection, automatic voltage regulation, and a CO sensor add to its safety and reliability. While the generator is on the heavier side and may produce some noise, its power, long run time, and tri-fuel versatility make it an excellent choice for those needing a dependable home backup power source.
