As the GP8000E and the XT8500EFI are both Generac generators, they benefit from the same level of quality and attention to detail.
Power Comparison
The following charts are provided to show you at a glance how the main specs of the Generac GP8000E compare to the Generac XT8500EFI.
- Power: With a running wattage of 8,500 W, the Generac XT8500EFI will allow to power more appliances and tools than the 8,000 running watts of the Generac GP8000E. However, as the 2 generators have the same starting watts (10,000 W), they will both give you the same boost needed to start the motor of your most demanding appliances.
- Runtime: When running at a 50% load, the GP8000E enjoys a higher approximate runtime on a full tank than the XT8500EFI. It can deliver power for around 10 hours, whereas the XT8500EFI will be able to power your appliances for around 9 hours.
- Fuel Efficiency: With a gasoline consumption at 50% load of 0.89 GPH (gallon per hour), the XT8500EFI is less fuel efficient than the Generac GP8000E with its 0.79 GPH. The latter will therefore be more economic to run than the former.
- THD: The Generac XT8500EFI with its low THD (<5%) is the only of these 2 generators that allows you to safely power your sensitive electronic devices (the Generac GP8000E has a THD <20%, which is too high for electronic products).
Portability Comparison
- Bulkiness: When compared, the Generac XT8500EFI and its dimensions of L31.4" x W20.5" x H26.5" offer a slightly more compact experience than the L27.2" x W27" x H26.5" of the Generac GP8000E.
- Weight: With a weight of 198 lbs, the GP8000E is slightly less heavy than the XT8500EFI (which weighs 214 lbs).
- Portability: Both products benefit from a wheel kit, which greatly enhances their maneuverability. Both offer a folding handle, which improves your grip when you wish to move them around.
Feature Comparison
- Starting System: Both devices can be started either via a pull-start mechanism or an electric starter.
- EFI: The Generac XT8500EFI 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: The GP8000E and the XT8500EFI both offer 5 AC outlets. They also 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 GP8000E's and the XT8500EFI'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: Both units benefit from Generac's COsense® carbon monoxide monitoring technology.
