Liquid-cooled generators are designed for extended use, often capable of running continuously for several days—up to 7 days or more—during an outage without overheating.

These generators are more efficient in terms of propane consumption, burning fuel at a slower rate, which is beneficial during long-term use.

This makes them ideal for large homes, businesses, or industrial settings where a reliable and consistent power source is essential.

However, they come with a higher cost, require more complex maintenance, and occupy more space due to their larger size.

Air-cooled generators are more budget-friendly and easier to maintain, making them suitable for smaller or medium size homes.

These generators are typically capable of running for around 12-24 hours at a time before needing a cool-down period to prevent overheating.

They also have a higher propane burn rate, consuming fuel more quickly than liquid-cooled models, which can make them less efficient for long-term use.

While noisier and with a shorter operational lifespan, air-cooled generators offer a practical solution for short-term power needs or less demanding applications.
