Buying Guide
What should I consider when choosing an LP gas powered generator?
Key factors include peak and running wattage, fuel flexibility, and RV readiness. Choose a model with enough running watts to cover essential appliances during an outage, plus a margin for startup surges.
How do I choose between propane and gasoline options?
Propane stores longer and is cleaner for indoor use, but gasoline often provides higher power and longer runtime in some models. Dual-fuel units offer flexibility if you have both fuel types available.
What about noise and portability?
Inverter generators and models labeled as quiet operation typically produce less noise, which is important for camping or residential use. If portability is essential, prioritize lighter units with ergonomic handles or wheels.
What outlets and safety features matter?
Look for 120V outlets, RV outlets, and transfer-switch compatibility if you plan a whole-home backup. Safety features like CO detectors, rubber outlet covers, and automatic shutdown increase reliability in emergencies.
How much capacity do I need for a full-home backup?
Assess the total wattage of your essential devices. For larger homes, higher-output dual-fuel units with transfer-switch readiness are typically required. For RVs, ensure RV-ready and 30A/50A outlets are present.
Maintenance and setup considerations
Check included accessories (oil, funnel, hoses, toolkit) and whether minimal assembly is required. Regular oil changes and safe storage practices extend generator life and reliability during outages.
FAQ
- Q: Are LP gas generators safe to use indoors?
- A: Use only outdoors or in well-ventilated spaces; CO safety features help but cannot remove all risk of fumes indoors.
- Q: Do these generators require a transfer switch?
- A: A transfer switch is recommended for home backup to prevent backfeeding and to simplify power management during outages.
- Q: Can I run a generator for long periods?
- A: Yes, with proper fuel supply, ventilation, and routine maintenance; monitor fuel levels and follow manufacturer guidelines.
- Q: Is propane more economical than gasoline?
- A: Fuel costs vary by location and time; propane can be more stable and easier to store, but running efficiency depends on the model and load.
- Q: What is “dual fuel” exactly?
- A: Dual fuel generators run on gasoline or propane, giving you flexibility based on fuel availability and cost.
