SEGUMA J1772 EV Charger Extension Cable 20ft (50A) — UL Listed, IP66 Weatherproof, Full-Copper

If your electric vehicle or plug-in hybrid is parked where the factory cable won't quite reach, this SEGUMA extension cord adds six meters of safe, high-current connection without sacrificing performance. Built with heavy-gauge copper conductors, a durable TPE jacket and precision-plated contacts, it’s engineered for frequent outdoor use and simple plug-and-play operation with standard J1772 chargers.

How does this extension keep charging fast and stable?

The cable is rated for up to 50 amps, allowing Level 2 charging at high current when supported by your EV and charger. Thick, 100% copper conductors minimize voltage drop, and silver-plated inlet contacts improve conductivity to reduce heating under load.

• 50A maximum current for rapid Level 2 charging
• Full-copper conductors to limit power loss over 20ft/6m
• Silver-plated connector contact surfaces for lower resistance

Will this work in bad weather or outdoor environments?

The SEGUMA extension is built for outdoor durability with a robust TPE outer jacket and IP66-rated protection against water and dust. It resists rain, splashes and typical garage or driveway conditions, so it’s suitable for year-round use when installed properly.

• IP66-rated housing for reliable weather resistance
• TPE jacket resists abrasion, UV and temperature changes
• Rugged molded J1772 plug and inlet for repeated use

Is it compatible with my EV and charging equipment?

Designed for universal J1772 connections, this extension works with common Level 1 and Level 2 charging stations and most electric vehicles sold in regions using the J1772 standard. It is UL-listed to meet recognized electrical safety benchmarks for such accessories.

• Standard J1772 male plug and female inlet for broad compatibility
• Compatible with Level 1 (120V) and Level 2 (240V) chargers supporting 50A
• UL listing indicates independently tested safety compliance

How easy is it to install and maintain?

Installation is straightforward: simply connect the male J1772 to your EV or charger and the female inlet to the station or cable end. The cord needs no tools or setup, and routine care involves wiping clean and storing coiled off the ground to avoid damage.

• Plug-and-play operation with no special tools required
• Durable moldings and TPE jacket require minimal maintenance
• Store coiled in a dry place when not in use to prolong life

Who is this for? The SEGUMA 20ft J1772 extension cable suits EV drivers who need extra reach without compromising charging speed — homeowners whose parking spots are set back from a charger, renters who require a temporary solution, and fleet operators seeking flexible connections. It’s best for vehicles and charging equipment that accept J1772 connectors and can benefit from up to 50 amps of current. SEGUMA supports the product with a one-year guarantee and customer assistance if you encounter operational concerns.
