Buying Guide: Gasoline-Powered Generators For Your Needs
- Fuel flexibility: Dual-fuel units let you switch between gasoline and propane, providing more versatility during fuel shortages or outages.
- Power needs: For whole-home protection, aim for 8000–13000+ watts with a transfer-switch-ready outlet. For RVs or camping, 3500–6000 running watts with RV-ready outlets is often sufficient.
- Starting method: Electric start is convenient, especially after a storm. Consider remote start if you anticipate frequent outages.
- Run time and fuel capacity: Larger tanks extend runtimes, typically at reduced efficiency. Balance tank size with portability.
- Safety features: CO sensors, automatic low-oil shutdown, and rubber outlet covers improve safety in home and outdoor use.
- Portability and noise: Inverter or lighter models offer quieter operation and easier transport. Heavier units may require wheels and a sturdy setup.
- Outlets and transfer readiness: Ensure you have the correct outlets for your transfer switch, RV, and common household devices.
Frequently Asked Questions
- What should I consider when choosing wattage?
Answer: Base your choice on the total load you plan to power. For whole-home backup, select a unit with higher running watts and peak watts to accommodate startup surges of HVAC and appliances. - Is dual-fuel better than single-fuel?
Answer: Dual-fuel offers flexibility during fuel shortages, but may be heavier and more expensive. Choose dual-fuel if you expect fuel reliability issues. - Do I need a CO detector with a generator?
Answer: Yes. Many models include CO shutdown features, but a standalone CO detector adds an extra layer of safety, especially indoors or in enclosed spaces. - What is transfer-switch readiness?
Answer: It enables safe, manual or automatic connection to home circuits, allowing powered appliances to switch from grid to generator without backfeeding the utility. - Can these generators power a whole house?
Answer: Some models can, particularly those in the 9000–13000-watt range with transfer-switch readiness. Always calculate your essential circuit load before purchase. - What about noise levels?
Answer: Inverter-based or mid-range portable units tend to be quieter than traditional open-frame generators, which is important for residential use and campground safety.
