As the EU1000i and the EM5000SX are both Honda generators, they benefit from the same level of quality and attention to detail. The EU1000i belongs to the Super Quiet series (EU), which is ideal for recreational and home backup applications. The EM5000SX is from the Deluxe series (EM), which is suitable for home backup and general purpose situations.

Power Comparison

The following charts are provided to show you at a glance how the main specs of the Honda EU1000i compare to the Honda EM5000SX.

  • Engine: The 389cc engine of the EM5000SX is significantly bigger than the EU1000i's engine, which has a displacement of 49.4cc.
  • Power: With a running wattage of 4500 W, the Honda EM5000SX will allow to power more appliances and tools than the 900 running watts of the Honda EU1000i. Moreover, compared to the 1000 starting watts of the EU1000i, the EM5000SX and its starting wattage of 5000 W will give more power to start the appliances which require an additional boost to get their motor running.
  • Runtime: When running at a 50% load, the EM5000SX enjoys a higher approximate runtime on a full tank than the EU1000i. It can deliver power for around 10.5 hours, whereas the EU1000i will be able to power your appliances for around 5 hours.
  • Fuel Efficiency: With a gasoline consumption at 50% load of 0.59 GPH (gallon per hour), the EM5000SX is less fuel efficient than the Honda EU1000i with its 0.11 GPH. The latter will therefore be more economic to run than the former. Inverter generators like the Honda EU1000i are usually much more fuel efficient and quiet.
  • THD: The Honda EU1000i with its low THD (<3%) is the only of these 2 generators that allows you to safely power your sensitive electronic devices (the Honda EM5000SX has a THD <10%, which is too high for electronic products).
  • Noise: There's an important difference in the emitted noise between these 2 generators. In fact, the EU1000i produces as low as 42 dBA, but the EM5000SX is rated for a minimum dBA of 63. As previously mentioned, inverter generators such as the EU1000i offer a much quieter operation.

Portability Comparison

  • Bulkiness: With dimensions of L17.8" x W9.5" x H14.9", the Honda EU1000i offers a much more compact experience of power generation than the Honda EM5000SX and its L41.1" x W27.8" x H28.3".
  • Weight: Weighing 28.7 lbs, the EU1000i is much lighter than the 226.4 lbs of the EM5000SX.
  • Portability: As the EM5000SX benefits from a wheel kit, it is easier to move it once on the ground than the EU1000i, because the latter doesn't have one. The EU1000i has a standard handle and the EM5000SX a folding handle, to help you better manipulate them.

Feature Comparison

  • Starting System: While these two devices can both start thanks to a conventional pull-start mechanism, the Honda EM5000SX has the advantage of also being able to get running via a convenient electric starter. The Honda EM5000SX offers another layer of convenience, as it can be remotely started.
  • Outlets: With a total of 6 AC outlets, the EM5000SX offers more AC receptacles than the EU1000i, which has 2 AC outlets. Moreover, the EM5000SX has the advantage of featuring GFCI outlets. The former also offers a DC output. In addition, it is worth noting that only the Honda EM5000SX can also produce 240V. For more detailed information regarding all their respective receptacles, refer to the EU1000i's and the EM5000SX's product pages.
  • Data Center & Fuel Gauge: Being equipped with a data center, the Honda EM5000SX allows for a better monitoring of its power generation than the Honda EU1000i. Besides that, thanks to a fitted fuel gauge, the Honda EM5000SX provides instant visibility of the fuel level.
  • Technology: Both units benefit from Honda CO Minder carbon monoxide monitoring technology. Besides that, the Honda EM5000SX offers you greater convenience by allowing you to monitor its vital stats via the My Generator mobile app.
