Buying Guide: Key Purchase Considerations
Power needs and fuel flexibility: Determine your essential circuit load and choose a generator that delivers enough running watts on your preferred fuel. Dual‑fuel models provide flexibility during fuel shortages or long outages.
Transfer switch compatibility: For permanent or semi-permanent backup setups, ensure the unit is transfer switch ready or comes with features that simplify hard‑wiring to a home’s electrical panel.
Outlets and safety: Look for a mix of 120V outlets, RV outlets, and a dedicated transfer switch connection, plus rubber outlet covers for weather resistance. CO safety features are highly valued for peace of mind around occupied spaces.
Run time and tank size: Larger tanks extend runtime, especially at partial loads. Compare gasoline versus propane efficiency to estimate daily usage during outages.
Starting method and ease of use: Electric start with a remote key fob or switch is convenient, while a simple pull start can suffice in emergencies. Consider noise levels if you live in a quiet‑neighborhood area or rent a campsite.
Portability vs. capacity: Heavy, high‑wattage units offer more continuous power but require wheels, handles, and potentially extra storage space. Balance mobility with power needs based on your home layout or camping plans.
Maintenance and support: Check warranty terms, included tools, and parts availability. A model with CO sensors and automatic shutoff adds a layer of safety and reduces risk during operation.
