SEGUMA EV Extension Cable for Tesla NACS 21ft 50A 240V — Weatherproof, 12kW Rated

SEGUMA EV Extension Cable for Tesla is a 21-foot, 50A NACS extension cord that extends Tesla Level 1 and Level 2 charging reach at 240V with weatherproof, high-strength construction.

If your Tesla charger cable just falls short of the parking spot, this SEGUMA extension cord adds 21 feet of safe, rated reach without changing your wall connector or mobile charger. Built to deliver up to 50 amps at 240 volts, the cable is intended for home and destination charging where added length matters. It is designed specifically for Tesla's NACS connectors and for use with Level 1/Level 2 charging equipment; it is not compatible with Superchargers.

How much additional reach and power does this extension provide?

The SEGUMA extension cable adds 21 feet to your existing NACS charging lead while supporting up to 50A at 240V, allowing stable charging performance up to approximately 12 kW. That extra length helps you park more flexibly without moving your Wall Connector or mobile charger.

• Current rating: 50 amps
• Voltage: 240 V, suitable for Level 1 and Level 2 chargers

Will this work with all Tesla chargers and vehicles?

The extension is built for Tesla equipment that uses the NACS standard: Wall Connectors (all generations), Destination Chargers, and compatible mobile chargers up to the stated rating. It also fits Tesla Model 3, Y, S, X and Cybertruck vehicles, but it does not function with Tesla Superchargers or override any vehicle-specific latch or door controls.

Who is this for: The SEGUMA 21-foot 50A NACS extension cable is aimed at Tesla owners who need extra reach for home, garage, or destination charging without investing in rewiring or repositioning charging equipment.
