Buying Guide
What load will you back up? Determine required running watts to cover refrigerators, HVAC fans, sump pumps, lights, and communication devices. For essential loads, a portable option with at least 1000–3000Wh may suffice. For whole-home protection, consider standby generators with automatic transfer switches installed outdoors.
What fuel makes sense for you? Gasoline units are portable and fast to deploy, but require storage and ventilation. Dual-fuel models offer flexibility between gasoline and propane. Standby generators usually run on natural gas or propane and stay permanently installed; they’re best for consistent outages.
How portable do you need it? If you frequently camp, RV, or need a flexible power source, a compact portable unit with a solid continuous watt rating is ideal. For stable home operation, plan for higher capacity or a dedicated standby system that automatically switches on during an outage.
Safety, maintenance, and extensions: Ensure proper ventilation for gasoline units, and follow local codes for outdoor placement. Consider a maintenance plan or service partner for standby systems. If you expect extended outages, calculate total runtime on a full tank and understand fuel burn rates.
FAQ
- What is the difference between a portable generator and a standby generator?
Portable units run on fuel and require manual startup during outages; standby systems are permanently installed with automatic transfer switches and often require professional installation. - Can these generators power a full house?
Some portable units can power many essential loads, but a true full-house system typically requires a standby generator with an automatic transfer switch. - Do I need a solar panel to use a Jackery portable power station?
No, but solar panels can recharge the unit, extending its use in off-grid scenarios. - What safety considerations matter for outdoor generators?
Place outside, away from windows and doors, with proper ventilation to avoid carbon monoxide buildup. Follow manufacturer guidelines for storage and maintenance. - How do I determine the right wattage for my home?
List essential appliances and their running watts, then sum them with a buffer. A professional assessment can help align your choice with seasonal needs. - Is dual-fuel better than single-fuel for home backup?
Dual-fuel offers flexibility and can adapt to fuel availability, which can be advantageous during extended outages.
