Buying Guide
What to consider when choosing surge protected extension cords
- Joules rating: Higher joules mean stronger surge protection. For electronics-heavy spaces, prefer models with 900–2700+ joules.
- Outlet spacing: Wider spacing helps fit large adapters and prevents blockages. Look for 1.8–2.2 inches or more between outlets.
- USB ports: Check total USB output and USB-C availability for fast charging needs. Some models include smart charging to optimize speed.
- Cord length and design: Flat plugs save space behind furniture; longer cords offer flexibility but require better cord management.
- Number of outlets: Match to your device count; if you routinely power many devices, a tower or 12+ outlet strip can simplify setup.
- Safety features: Overload protection, circuit breakers, and indicator lights help confirm protection status and safety.
- Certifications: ETL or UL listings indicate compliance with safety standards; prefer models with reputable certifications.
