Portable Generators (Emergency Backup Power Guide)
Part of our Backup Power & Generators Hub.
Portable generators provide temporary electricity during power outages. These generators are commonly used during storms, grid failures, and emergency situations when homes lose access to utility power.
Unlike permanent standby generators, portable units can be stored when not needed and quickly deployed during outages.
What Portable Generators Can Power
Portable generators are designed to supply electricity to essential appliances rather than powering an entire home.
- Refrigerators and freezers
- Lighting circuits
- Internet routers and modems
- Small kitchen appliances
- Space heaters or fans
- Sump pumps
Portable Generator Size Guide
| Generator Size | Power Output | Typical Use |
|---|---|---|
| Small | 1,000–2,000 watts | Electronics and lights |
| Medium | 3,000–5,000 watts | Refrigerators and appliances |
| Large | 6,000–8,000 watts | Multiple appliances and tools |
Portable Generator Fuel Types
Gasoline Generators
Gasoline-powered generators are the most common type. They are widely available and typically offer strong power output at relatively affordable prices.
Dual-Fuel Generators
Dual-fuel models can operate using either gasoline or propane, offering flexibility during fuel shortages.
Inverter Generators
Inverter generators produce cleaner electricity that is safer for sensitive electronics such as laptops and televisions. They also operate more quietly than traditional generators.
Safety Considerations
- Never operate generators indoors or inside garages
- Keep generators at least 20 feet from buildings
- Use proper extension cords rated for generator output
- Install carbon monoxide detectors in your home
Portable Generator vs Standby Generator
Portable generators provide temporary backup power but require manual operation and fueling. Standby generators automatically activate when grid power fails and can support an entire home.
