Buying Guide
What to check before buying a 100 ft, 15 amp outdoor extension cord:
- Gauge: 12 gauge offers higher wattage capacity and better durability for heavy-duty tools; 14 gauge is lighter and cheaper but supports fewer high-demand devices.
- Weather resistance: Look for IP-rated or weatherproof jackets (SJTW or SJTW-C) and cold-resistant performance for winter use.
- Safety features: Lighted ends help confirm power status; ETL/cETL listings indicate conformity to safety standards.
- Visibility: Yellow or bright jackets improve visibility to reduce trip hazards in dim spaces.
- Storage and handling: Consider cords with flexible, bend-resistant jackets and strain relief to extend life after frequent use.
- Application: Match wattage needs (watts = amps × voltage) to avoid overloading the cord, especially when using power tools or heaters.
