As the Honda EU7000iS and the Yamaha EF6300iSDE 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 Yamaha EF6300iSDE compare to the Honda EU7000iS.

  • Power: As both the Yamaha EF6300iSDE and the Honda EU7000iS share the same running wattage of 5,500W, they will both allow you to simultaneously power the same appliances. However, compared to the 6,300 starting watts of the Yamaha EF6300iSDE, the Honda EU7000iS and its starting wattage of 7,000 W will give more power to start the appliances which require an additional boost to get their motor running. Out of these two models, only the Honda EU7000iS is parallel capable, allowing for increased power when paired to another compatible unit.
  • Runtime: When loaded to 25% of their max capacity, the Honda EU7000iS offers a higher runtime on a full tank than the Yamaha EF6300iSDE: it can operate for up to 16 hours, whereas the Yamaha EF6300iSDE offers a maximum runtime of 13.3 hours.
  • Fuel Efficiency: With a gasoline consumption at 25% load of 0.32 GPH (gallon per hour), the Honda EU7000iS is more fuel efficient than the Yamaha EF6300iSDE and its 0.34 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 (<4% for the Yamaha EF6300iSDE and <3% for the Honda EU7000iS) and are therefore perfectly suitable to safely power your sensitive electronic devices.
  • Noise: With a noise of 52 dBA, the Honda EU7000iS allows for a quieter operation than the 58 dBA of the Yamaha EF6300iSDE. The former will therefore be the most suitable for you if you take noise emission seriously.

Portability Comparison

  • Bulkiness: With dimensions of L30.7" x W24.3" x H27.2", the Yamaha EF6300iSDE offers a much more compact experience of power generation than the Honda EU7000iS and its L33.4" x W27.6" x H28.4".
  • Weight: The EF6300iSDE and its 216 lbs is somewhat lighter than the 263.2 lbs of the EU7000iS.
  • Portability: Both products benefit from a wheel kit, which greatly enhances their maneuverability. The Yamaha EF6300iSDE has a double handle and the Honda EU7000iS a folding handle, to help you better manipulate them.

Feature Comparison

  • Starting System: While you can get both devices running via a convenient electric starter, the Honda EU7000iS is the only one which benefits from an additional conventional pull-start mechanism. The Honda EU7000iS offers another layer of convenience, as it can be remotely started.
  • EFI: The Honda EU7000iS benefits from an Electronic Fuel Injection (EFI) system, which enhances its engine's reliability, lowers its fuel consumption, improves its startup, reduces its servicing, boosts its stale fuel resistance, and offers better altitude adaptability.
  • Outlets: With a total of 6 AC outlets, the Honda EU7000iS offers more AC receptacles than the Yamaha EF6300iSDE, which has 4 AC outlets. Yet, they both feature GFCI outlets. In addition, it is worth noting that they can both produce either 120 or 240V. For more detailed information regarding all their respective receptacles, refer to the Yamaha EF6300iSDE's and the Honda EU7000iS'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 fitted with a fuel gauge allowing to see their fuel level at a glance.
  • Technology: They both benefit from a technology that monitors the ambient CO level. Besides that, the Honda EU7000iS offers you greater convenience by allowing you to monitor its vital stats via the My Generator mobile app.

  1. Good comparison. I have owned the Yamaha 3000is for 8 years now. It performs flawlessly, starts every time and continues to run smooth. I drain the fuel meticulously after use and leave no remaining fuel in the carburetor. I would prefer the fuel injection that the HONDA offers but have no issues with YAMAHA’S carbonation system of fuel delivery. So I don’t really know if the higher price and 30% additional weight is worth it. I have logged about 250 hours on my YAMAHA 3000is and am leaning towards the purchase of a YAMAHA 6300isE This will run my whole house
    (2500 sq ft) (NOT INCLUDING the central AC) via a transfer switch at the Electrical box.
