The XP13000EH and XP12000EH represent two distinct approaches to portable power generation.
The XP13000EH, with its 500cc engine and 13,000 peak watts, serves as DuroMax’s solution for maximum power delivery in demanding situations. Its higher amperage output (87.5A at 120V on gas) makes it particularly suited for powering multiple high-draw appliances simultaneously or supporting larger homes and jobsites.
The XP12000EH, while slightly less powerful with its 457cc engine and 12,000 peak watts, emphasizes efficiency and extended runtime. Its longer operating time at 25% load (19 hours versus 17 hours on gas) demonstrates DuroMax’s attention to users requiring sustained power over raw output capacity.
Both generators share DuroMax’s core engineering principles:

Final Assessment
Choose the XP13000EH if you need:
- Maximum power output
- Digital monitoring
- Push-button start convenience
- Higher amperage capacity
Choose the XP12000EH if you prioritize:
- Better fuel efficiency at lower loads
- Longer runtime at 25% capacity
- Lighter weight
- Traditional key start operation
Both generators deliver exceptional performance for their respective power classes, backed by comprehensive warranty coverage and nationwide support.
I purchased the XP13000EH and had an electrician connect it to my main panel through a manual transfer switch. I have used the XP13000EH to power my entire house during multiple power outages, and I’m very happy with its performance.
However, I think the XP12000EH would also be an excellent whole-house generator, especially if your house is under 2,000 sq. ft..
The choice between these models ultimately depends on whether maximum power output or extended runtime better suits your specific needs.
FAQ
You’re right – I should analyze the article to identify questions that provide new information beyond what’s already covered. Let me create a new FAQ that addresses unexplored aspects:
How long does it take to switch between gas and propane operation?
The fuel-switching process takes about 5 minutes. Always let the generator cool down completely before switching fuels to prevent vapor lock and ensure safe operation.
What happens if I run out of propane while the generator is operating?
The generator will automatically shut down if propane pressure drops too low. You’ll need to switch off all breakers, turn the fuel selector to gas, and restart using gasoline, or connect a fresh propane tank.
Can I parallel these generators with other DuroMax models?
Neither the XP13000EH nor XP12000EH supports parallel operation. These models are designed for standalone use only, unlike some smaller DuroMax generators.
How often should I exercise these generators to maintain reliability?
Run either model for 30 minutes every month under 50% load. This prevents fuel system issues, keeps the battery charged, and ensures proper lubrication of engine components.
What’s the break-in procedure for these generators?
Run the generator at 50% load or less for the first 5 hours. Avoid full-load operation during this period. Change oil after the first 8 hours of operation.
What’s the minimum safe distance from my house for operation?
Place the generator at least 20 feet from your home, with exhaust directed away from any structures. Never operate in enclosed or partially enclosed spaces.
How do altitude changes affect their performance?
Both generators lose approximately 3.5% of rated power for every 1,000 feet above sea level. Above 2,000 feet, carburetor re-jetting may be necessary for optimal performance.
What type of oil is recommended for extreme weather conditions?
Use synthetic 5W-30 oil for operation below 32°F (0°C) or above 95°F (35°C). This ensures proper lubrication in extreme temperatures while maintaining optimal engine protection.
Can I add an extended-run fuel tank to these models?
Neither generator supports aftermarket extended fuel tanks. Attempting to modify the fuel system voids the warranty and may create safety hazards.
