GENMAX Inverter Generator
This little guy is the “Grab-and-Go” king. While it won’t power a central AC, the GENMAX Generator is perfect for keeping the absolute essentials alive—think phones, laptops, and a few lights. It’s incredibly lightweight, making it a favorite for camping trips or tailgating when you aren’t fighting a blackout.

- Eco-Mode: Adjusts engine speed to save fuel and reduce noise, perfect for quiet neighborhoods.
- Gas Powered: Simple, traditional fuel source you can find anywhere.
Generac Guardian 10kW Standby
This is the heavy artillery. The Generac Guardian isn’t just a generator; it’s a permanent home upgrade. It hooks directly into your home’s natural gas or liquid propane supply and turns on automatically the second the power cuts out. You don’t have to drag anything outside or pull a cord in the rain. It comes with a 100 Amp transfer switch, meaning it integrates seamlessly into your breaker box.
Key Features:
- Automatic Operation: Detects outages and starts up within seconds—even if you aren’t home.
- No Refueling: Runs on your home’s existing Natural Gas or LP line, so no hunting for gas cans.
- WiFi Enabled: Monitor the status and maintenance schedule right from your smartphone.
- True Whole House: 10kW is enough to run major appliances, pumps, and lights simultaneously.
Westinghouse 14500 Peak Watt Tri-Fuel
If you want massive power without the permanent installation cost of a standby unit, the Westinghouse 14500 is a monster. This “Tri-Fuel” beast runs on Gas, Propane, or Natural Gas, giving you ultimate flexibility during a fuel shortage. With 14,500 peak watts, it can easily handle high-demand appliances like central air conditioners, sump pumps, and refrigerators all at once.
Key Features:
- Tri-Fuel Capability: Switch between Gasoline, Propane, and Natural Gas on the fly.
- Massive Output: 14,500 Peak Watts is practically commercial-grade power for a portable unit.
- Remote Start: Includes a key fob so you can start it from the comfort of your porch.
- Ready to Rock: Comes transfer-switch ready with 50A and 30A outlets built-in.
WEN 14500-Watt Tri-Fuel Generator
The WEN 14500-Watt is the direct rival to the Westinghouse, offering similar “Tri-Fuel” versatility at a competitive price point. It’s built for the homeowner who wants options. Whether you have a propane tank lying around or a natural gas line on your patio, this generator hooks up and delivers serious juice. It features a rugged wheel kit, making it easier to roll out of the garage when the storm hits.
Key Features:
- Fuel Flexibility: Run it on whatever fuel you have available—Gas, LPG, or NG.
- Electric Start: No arm-breaking pull cords; just turn the key (battery included).
- Safety First: Includes a CO Watchdog that shuts the unit down if carbon monoxide levels get too high.
- High Capacity: 8.2-gallon gas tank provides up to 12 hours of run-time at half load.
DuroMax XP13000HX Dual Fuel
DuroMax is known as the “Powerhouse,” and the XP13000HX lives up to the name. It is a Dual Fuel unit (Gas and Propane) that features “CO Alert” technology for safety. This unit is designed with a fully loaded power panel, making it a favorite for RV owners and homeowners alike who need 240V power for heavy-duty appliances. It’s built like a tank and handles surges with ease.
Key Features:
- Dual Fuel Technology: flexibility to run on gasoline or cleaner-burning propane.
- CO Alert: Automatically shuts down if unsafe levels of carbon monoxide are detected.
- Push Button Start: effortless startup with a simple push of a button.
- All-Metal Construction: Built tough to withstand job sites and rough weather conditions.
Buying Tips for Whole House Generators
- Calculate Your Watts: Don’t guess. List your “must-haves” (Fridge = 700W, Sump Pump = 1000W, AC = 3500W+) and add them up. Buy a generator with at least 20% more running watts than you need.
- Tri-Fuel is King: In a real emergency, gas stations run dry. Having a unit that runs on Propane (which stores forever) or Natural Gas (infinite supply) is a game-changer.
- Get a Transfer Switch: Never plug a generator into a wall outlet (backfeeding). It kills utility workers. Install a manual transfer switch or an interlock kit to power your house circuits safely.
The “Break-In” Period.
Don’t wait for an emergency to unbox your generator. Run it for 5 hours with a light load, then change the oil immediately. This flushes out metal shavings from the manufacturing process and ensures your engine lasts for years.
