Buying Guide
What kind of power you actually need?
Assess peak watts versus running watts to match your essential appliances or circuits. A larger home backlog typically requires higher peak watts and steady running watts, while RV or camping use may do fine with inverter models.
Fuel sources and availability
Gasoline engines are common and provide strong power, but propane and natural gas offer flexibility when gasoline is scarce. Consider fuel storage, delivery, and ease of refueling in your plan.
Portability and storage
Weight, wheel kits, and compact dimensions determine how easily you move the unit around your property or campsite. Inverter generators often weigh less and run more quietly, but may provide less total output than traditional open-frame models.
Outlets and compatibility
Check the type and number of receptacles, transfer switch readiness, RV connections, and safety features like rubber covers and ground fault protection to ensure compatibility with your loads.
Runtime and fuel efficiency
Look at fuel tank size and consumption at typical loads. Longer runtime reduces refueling during outages, especially in extended outages or remote locations.
Frequently Asked Questions
- What does peak wattage mean? It’s the maximum instantaneous power the generator can provide for a short time to start appliances.
- Do I need a transfer switch? A transfer switch simplifies switching power from the grid to the generator and improves safety for home backup.
- Is inverter power better for home use? Inverters are quieter and more efficient for smaller loads, with good line stability for electronics.
- Can I run a whole house with a portable generator? Large homes typically require high‑output dual‑fuel units or multiple units with a transfer switch; portable models cover essential circuits or critical loads.
- How do I determine run time? Run time depends on fuel tank size and the load. Lighter loads extend runtime significantly.
- Are dual‑fuel generators worth it? Yes, they offer flexibility during fuel shortages and provide options for different fuel availability.
