POWGRN NEMA 14-50P to NEMA 14-50R 10 FT Extension Cord

- 50A capacity with 125/250V rating; compatible with Level 2 EV charging such as Tesla Model 3, S, X, Y
- Weatherproof and durable: IP65 waterproof, wear-resistant jacket, flame retardant
- User-friendly insulated grip handle for safe plugging and unplugging
- Pure copper conductors for potential efficiency and safety
Best for: Users needing a short, highly portable option for close-in charging at home or a campground with a nearby outlet. Avoid this if you require a very long run or if your outlet is farther than 10 feet.
Limitation: The 10 ft length may require an extension only in tight spaces; check your EV charger’s distance to the wall outlet before choosing.
POWGRN NEMA 14-50P to 14-50R 50 Amp 15 Ft Extension Cord

- 50A, 125/250V, 6250/12500W capacity; STW jacket; designed for Level 2 EV charging
- Weatherproof, IP65 rated, corrosion and heat resistant; copper conductors
- Insulated handle and generous grip space to simplify plugging/unplugging
Best for: Moderate-length, outdoor charging scenarios where weather exposure is a factor and a sturdy handle is desirable. Consider this when a 15-foot reach matches your installation layout.
Limitation: Ensure correct plug type matching to your EV charger to avoid compatibility issues.
POWGRN NEMA 14-50P to 14-50R 75 Ft Extension Cord

- Long-run capability for outdoor installations far from the power source
- Weatherproof, IP65 waterproof and heat-resistant jacket; pure copper conductors
- Insulated handle for safer plugging/unplugging
Best for: Environments where the EV outlet is far from the vehicle, such as driveways with distant wall outlets or staging areas. Better for long-term outdoor use than shorter cords.
Limitation: A 75-foot extension can experience higher voltage drop; ensure your EV charger and vehicle can tolerate longer cords.
RVGUARD 50 Amp 50 Foot RV/EV Extension Cord

- 50A rating with 50A male (NEMA 14-50P) and 50A female (NEMA 14-50R)

- ETL/cETL certified; designed for RVs and Level 2 EV charging use
Best for: Users needing a mid-length, rugged option for outdoor charging in yards or RV sites. Choose this when weather exposure is a concern and you want a robust 50-foot reach.
Limitation: Heavier and less flexible than shorter cords; plan storage and handling accordingly.
