Buying Guide
- Power needs: Consider starting watts vs running watts. Oil and fuel efficiency influence runtime and performance under load.
- Fuel options: Gasoline-only units are common; tri-fuel or LPG-capable models offer flexibility during outages or remote use.
- Noise and THD: Lower noise levels improve suitability for residential use; a THD under 3% helps protect electronics.
- Portability: Weight, wheels, and handles affect transport; many models list around 89 lb with mobility kits.
- Safety features: CO sensors, automatic shutdown on low oil or high CO, and proper EPA/CARB compliance are important for indoors or RV use.
- Outlets: Ensure sufficient 120V outlets and RV/TT-30R or L5-30R options for your appliances and equipment.
- Fuel capacity and runtime: Larger tanks extend runtime; check runtime at common loads to plan outages or trips.
- Maintenance: Look for available service networks, oil change intervals, and warranty terms for long-term reliability.
