- Weatherproofing: For outdoor use, prioritize SJTW jackets and UV resistance to withstand sun and moisture.
- Conductor Material: Pure copper cores provide better conductivity and less resistance than aluminum; look for 12 AWG copper conductors for high-power needs.
- Safety Certifications: ETL or UL listings indicate compliance with safety standards; prefer listed cords for reliability.
- Outdoor vs. Indoor Use: Indoors may tolerate lighter jackets; outdoor cords should be rated for temperature extremes and moisture.
- Extra Features: LED indicators, reinforced blades, and flexible jackets improve usability and durability in challenging environments.
