Buying Guide

Choosing a predator dual fuel generator comes down to a handful of measurable factors. Start with your real loads, then match the fuel type, noise level and size to how you will use the unit. For a deeper look at noise, see How to Choose a Quieter Generator and Generator Decibel Ratings Explained: What dBA Numbers Mean.

Selection criteria

  • Running watts: the sustained load you need to support
  • Surge watts: the short burst needed to start motors
  • Fuel flexibility: gasoline, propane or both, and the rating for each
  • Noise: the manufacturer-specified dBA at a stated distance and load
  • Portability: weight, handles and wheel kits

Important features

Electric start is useful if you cannot reliably pull a recoil cord. Inverter designs produce cleaner power for electronics and run quieter at light load, though they cost more in watts per dollar. Dual-fuel operation helps when gasoline goes stale or is scarce, but propane typically gives lower rated output and shorter runtime per tank.

Specs to check

  • Rated watts on both gasoline and propane, not just the best-case number
  • Runtime at 50 percent load on each fuel
  • Outlet types, including 120V, 120/240V and 12V DC
  • Noise rating and the test distance used
  • Oil alert and low-oil shutdown features

Choosing by need

For camping and light electronics, a 3,000–3,500-watt conventional unit or an inverter design is usually enough. For a refrigerator, lights and a furnace blower, plan for roughly 5,000 to 6,500 running watts and a transfer switch. For well pumps and shop tools, check the surge rating of your largest motor before choosing. A 12,000-watt class unit is only needed for extended whole-home backup.

Things to watch out for

  • Never run any generator indoors, in a garage or in a partially enclosed space. Carbon monoxide can build up quickly.
  • Do not connect to household wiring without a properly installed transfer switch or interlock. Backfeeding can injure utility workers and damage equipment. Consult a licensed electrician for installation.
  • Propane output drops with cold weather and tank pressure. Plan for this in winter.
  • Stale gasoline causes starting problems. Use fuel stabilizer or rotate fuel regularly.

FAQ

What does dual fuel mean on a predator dual fuel generator?

Dual fuel means the engine can run on either gasoline or propane, usually by switching a fuel selector. Gasoline typically gives higher rated output, while propane offers longer storage life and cleaner starts in many conditions.

Is propane output lower than gasoline output?

In most dual-fuel designs, yes. Manufacturers usually list a lower rated wattage for propane. Check the rating for each fuel before sizing the generator to your loads.

How loud is a typical predator dual fuel generator?

Manufacturer-specified noise for conventional units in this category often falls between the mid-60s and mid-70s dBA at 23 feet, depending on size and load. Inverter designs usually run quieter at light load. Compare ratings only when the test distance and load are stated.

Can I run a predator dual fuel generator during a power outage in my house?

Yes, but only through a properly installed transfer switch or interlock kit. Never plug a generator into a wall outlet, because backfeeding endangers utility workers. A licensed electrician should handle installation.

How long does a tank last?

Runtime depends on load and tank size. Manufacturers usually publish runtime at 50 percent load. Propane runtime is often shorter than gasoline for the same load because of its energy content per unit of fuel.

Do I need an inverter model for electronics?

Many conventional generators produce acceptable power, but inverter units output cleaner, more stable power that is generally safer for sensitive electronics and medical devices. Confirm the total harmonic distortion rating if this matters to you, and consult the device maker if you rely on life-support equipment.

How often should I service a dual-fuel generator?

Follow the owner’s manual. As a general rule, check oil before each use, change it at the interval the manufacturer specifies, and inspect the air filter and spark plug regularly. Propane models still benefit from routine maintenance because the engine works just as hard.

Conclusion

A predator dual fuel generator makes sense when you want fuel flexibility and enough output for real household or work loads. For camping and a few essentials, the 3500-class and the Westinghouse inverter design are the most practical starting points. For a refrigerator, furnace blower and lights through a transfer switch, the 5500 or 6500 class fits well. Buyers running well pumps or shop tools should look at the 6500 and 8750 classes, checking surge ratings first. The 12000-class unit is for extended whole-home backup where size and noise are acceptable. Match the watts to your loads, check both fuel ratings, and plan placement and exhaust safety before you run it.
