As the Cummins Onan P4500i and the Honda EU3000iS 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 Honda EU3000iS compare to the Cummins Onan P4500i.

  • Power: With a running wattage of 3700 W, the Cummins Onan P4500i will allow to power more appliances and tools than the 2800 running watts of the Honda EU3000iS. Moreover, compared to the 3000 starting watts of the Honda EU3000iS, the Cummins Onan P4500i and its starting wattage of 4500 W will give more power to start the appliances which require an additional boost to get their motor running.
  • Runtime: When loaded to 25% of their max capacity, the Honda EU3000iS offers a higher runtime on a full tank than the Cummins Onan P4500i: it can operate for up to 20 hours, whereas the Cummins Onan P4500i offers a maximum runtime of 18 hours.
  • Fuel Efficiency: With a gasoline consumption at 25% load of 0.17 GPH (gallon per hour), the Honda EU3000iS is more fuel efficient than the Cummins Onan P4500i and its 0.19 GPH. The former's operation will therefore cost less in terms of the money spent on gasoline. Inverter generators like these 2 are of the most fuel efficient (and quiet) type.
  • THD: Both generators offer a low THD (<3% for the Honda EU3000iS and <3% for the Cummins Onan P4500i) and are therefore perfectly suitable to safely power your sensitive electronic devices.
  • Noise: With 50 dBA, the noise emitted by the Honda EU3000iS is slightly lower than the 52 dBA of the Cummins Onan P4500i. 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: Weighing 98 lbs, the Onan P4500i is much lighter than the 130.7 lbs of the EU3000iS.
  • Portability: As the Cummins Onan P4500i benefits from a built-in set of wheels, it is easier to move it once on the ground than the Honda EU3000iS, because the latter doesn't have one. The Honda EU3000iS has a double handle and the Cummins Onan P4500i a telecospic 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. The Cummins Onan P4500i offers another layer of convenience, as it can be remotely started.
  • Outlets: The Honda EU3000iS and the Cummins Onan P4500i both offer 3 AC outlets. None of them feature GFCI outlets. The latter also offers a DC output. In addition, it is worth noting that they both only produce 120V. For more detailed information regarding all their respective receptacles, refer to the Honda EU3000iS's and the Cummins Onan P4500i's product pages.
  • Data Center & Fuel Gauge: Being equipped with a data center, the Cummins Onan P4500i allows for a better monitoring of its power generation than the Honda EU3000iS. Besides that, these 2 products are equipped with a fuel gauge allowing to see their fuel level at a glance. For the Onan P4500i, this fuel gauge is digital and part of the data center.
  • Technology: The Honda EU3000iS benefits from a welcomed additional security feature: its CO Minder technology monitors carbon monoxide and automatically shuts off the generator if the ambient levels become unsafe.
