🔍 Buying Guide – How to Choose the Right 12,000-Watt Generator

Before picking a model, consider the following:

✅ Fuel Type

• Dual fuel (gas + propane) models offer flexibility during fuel shortages.
  
• Gas-only models are typically cheaper but less versatile.

Look for a unit with at least 8–12 hours of runtime at 50% load to get through a night or workday.

✅ Start Type

Electric start is more convenient, while remote start adds extra comfort.

✅ Portability

Most generators in this class are heavy. Make sure the model has durable wheels and handles if you plan to move it.

✅ Outlets & Transfer Switch Compatibility

Ensure the generator supports the types of connections you need (e.g., 120/240V twist-lock, GFCI outlets) and is compatible with your home’s transfer switch if using it for backup power.
