Buying Guide: Key Factors To Consider
- Power needs: Identify essential appliances and total running watts to ensure the generator can handle them simultaneously.
- Fuel type and availability: Gasoline is common, but dual-fuel options provide flexibility if propane is easier to source.
- Outlets and RV connections: Confirm a 30A TT-30R receptacle is present for RV use and check for additional 120V outlets for household devices.
- Runtime and fuel tank size: Larger tanks extend operation between refuels, but may increase size and weight.
- Noise level: Inverter models typically run quieter and deliver cleaner power ideal for electronics.
- Portability: Weight and built-in wheels/stools affect maneuverability in storage bays or campsites.
- Safety features: Look for low-oil shutdown, overload protection, and rubber outlet covers.
