WEN DF400i vs Predator 3500 - The Differences

Further down the page, you'll find some explanations regarding the key similarities and differences between the Predator 3500 and the WEN DF400i.

But before checking out explanations regarding their power, portability, and features, here's a table that summarizes the main pros of each of these 2 generators:

As the WEN DF400i and the Predator 3500 do not share the same manufacturer, their overall build and technology in use can vary.

Power Comparison

The following charts are provided to show you at a glance how the main specs of the Predator 3500 compare to the WEN DF400i.

  • Fuel: The WEN DF400i is a dual fuel generator. Thus, it has the advantage of being able to run either on gasoline or propane, whereas the other generator only runs on gasoline.
  • Power: With a running wattage of 3200 W, the WEN DF400i will allow to power more appliances and tools than the 3000 running watts of the Predator 3500. Moreover, compared to the 3500 starting watts of the Predator 3500, the WEN DF400i and its starting wattage of 4000 W will give more power to start the appliances which require an additional boost to get their motor running.
  • Runtime: We unfortunately lack the data to compare the runtimes of these 2 generators. One of the manufacturers only provides data @25% load, whereas the other only gives data @50% load. It makes little sense to compare runtimes at different loads.
  • Fuel Efficiency: For the same reasons as pointed out above, we do not see any sense in comparing fuel consumption at different loads. Inverter generators like these 2 are of the most fuel efficient (and quiet) type.
  • THD: Both generators offer a low THD (<5% for the Predator 3500 and <1.2% for the WEN DF400i) and are therefore perfectly suitable to safely power your sensitive electronic devices.
  • Noise: With 56 dBA, the noise emitted by the Predator 3500 is slightly lower than the 58 dBA of the WEN DF400i. While this difference could seem insignificant, the former should still be easier on your ears.

Portability Comparison

  • Bulkiness: As these two products share the same overall bulk, neither of them will really take up less storage space.
  • Weight: With a weight of 100 lbs, the DF400i is slightly less heavy than the 3500 (which weighs 102 lbs).
  • Portability: Both products benefit from a set of wheels, which greatly enhances their maneuverability. The Predator 3500 has a double handle and the WEN DF400i a folding handle, to help you better manipulate them.

Feature Comparison

  • Starting System: Both devices can be started either via a pull-start mechanism or an electric starter.
  • Outlets: The Predator 3500 and the WEN DF400i both offer 3 AC outlets. None of them feature GFCI outlets. Both of them also feature a DC output. However, the Predator 3500 does not provide an out-of-the-box USB connectivity. In addition, it is worth noting that they both only produce 120V. For more detailed information regarding all their respective receptacles, refer to the Predator 3500's and the WEN DF400i's product pages.
  • Data Center & Fuel Gauge: Each of these 2 portable generators is equipped with a data center allowing you to conveniently monitor some aspects of the power output. Besides that, these 2 products are equipped with a fuel gauge allowing to see their fuel level at a glance. For the DF400i, this fuel gauge is digital and part of the data center.
  • Technology: The Predator 3500 benefits from a welcomed additional security feature: its CO Secure technology monitors carbon monoxide and automatically shuts off the generator if the ambient levels become unsafe.
  • Fuel Shut Off: The WEN DF400i benefits from a fuel shutoff feature, which turns off the flow of fuel, allowing for the generator to use up the remaining fuel from the carburetor before automatically shutting down. This helps fight the build-up and blockages caused by stagnant fuel inside the carburetor, minimizing maintenance while prolonging the unit’s lifespan.
