Dual fuel capability provides crucial flexibility. If gasoline supplies run low, you can switch to propane, which stores for years without degrading. This gives you more options to keep the generator running during extended supply chain disruptions that often follow major disasters in 2026.

Do I need an electric start feature for a backup generator?

While not strictly necessary, electric start is highly recommended. In stressful, dark, or cold conditions, a simple key turn or push-button start is far easier and more reliable than pulling a recoil cord repeatedly. It ensures anyone in your household can start the generator when needed.

How do I maintain my generator so it’s ready for a long outage?

Follow a regular maintenance schedule: use fuel stabilizer, change the oil and filter as recommended, run the generator under load for 30 minutes monthly, and keep the battery charged. For cold-weather readiness, consider a battery tender and a cold weather kit to ensure instant starts.
