New vs. Used Generators: What to Know Before You Buy
Choosing between a new or used generator? Here’s how they stack up.
Feature | New Generators | Used Generators |
Warranty | Full manufacturer warranty | Limited or none (depends on unit) |
Customization | Built-to-spec for your needs | Limited to available inventory |
Condition | Brand-new, zero hours | Pre-owned, tested, and serviced |
Lead Time | Longer, varies by model | Shorter (in-stock units available) |
Price | Higher upfront cost | Cost-effective for tight budgets |
Both options can serve your needs well depending on your project timeline, budget, and technical requirements. Every used unit sold by Hatton Power is professionally inspected and serviced for performance and safety. We’re happy to walk you through what makes the most sense for your use case.

Lead times for new generators vary by model and supplier, usually 3 to 8 weeks. For in-stock used units, delivery can often be arranged within days. Contact us to check availability and lead times for your preferred system.
