Buying advice

Consider your power needs: for sensitive electronics, choose an inverter generator; for whole house backup, a conventional dual fuel model with high wattage. Quiet operation is important for camping or neighborhoods. Fuel type (gas, propane, diesel) affects runtime and storage. Check noise levels (dB) and runtime at 50% load. Budget models offer good value but may lack inverter technology or be noisier.
