bokman Tesla NACS Extension Cable 21 ft — 50A/12 kW Outdoor Rated, Low-Voltage Drop

bokman 21FT 50A NACS extension cable adds 21 feet of usable reach to your Tesla charger while delivering full 240V, 50A charging without power loss.

If your Tesla is parked where the existing charger cord just doesn’t reach, this bokman extension cable gives you the extra length and heavy-duty capacity you need. Built for the Tesla NACS (North American Charging Standard) connector, the cord supports up to 50 amps and 12 kW, is rated for outdoor use, and is compatible with Tesla Wall Connectors, Mobile Chargers, and Destination Chargers. It’s not compatible with Supercharger stations and its locking design requires stopping charge before unplugging.

How does this extension maintain full charging power?

The cable is engineered with low-resistance conductors and an appropriately sized gauge to deliver 240V at up to 50A without speed loss. That means you won’t take a charging penalty for adding 21 feet between charger and car when installed and used correctly.

• Rated for 50A and 12 kW continuous power delivery
• Appropriate conductor gauge to minimize voltage drop
• Designed for use with Level 1/2 home and destination chargers

Is the bokman extension safe to use outdoors and in cold weather?

Yes — the cable is built to withstand varied climates with an IPX5 splash-resistant rating and an operational range from -30°C to +50°C. The durable jacket and sealed connectors resist moisture and temperature stress for year-round use.

• IPX5 water-resistance rating for rain and spray protection
• Extreme temperature tolerance for winter and summer climates
• Robust jacket to resist abrasion and UV exposure

Will this work with my Tesla and how do I disconnect it?

This extension is compatible with all Tesla models that use the NACS connector, including Model 3, Y, S, X, and Cybertruck. Note the plug incorporates a secure lock during charging; you must stop charging from the car or Tesla app before unplugging — there is no button on the extension to release the connector.

• Fits Tesla NACS-equipped models and Tesla chargers (Wall Connector, Mobile Charger)
• Secure locking prevents accidental unplugging during charge
• Disconnect procedure: stop charge in-car or via app, then unplug

Can I use this at any public charger or replace the factory cable?

The extension is designed for Level 1 and Level 2 charging stations and home installations; it is not compatible with Tesla Superchargers. It works as an extension to your existing Tesla charging equipment rather than a replacement for permanently installed charging hardware.

• Compatible with Level 1/2 public and private charging stations
• Not compatible with Tesla Supercharger stations
• Meant to extend existing Tesla chargers, not replace fixed installations

Who this is for: The bokman 21FT 50A NACS extension cable is aimed at Tesla owners who need extra reach to charge conveniently in garages, long driveways, shared parking, or destination spots. It suits drivers who want full 50A charging capacity without moving their vehicle, outdoor durability for all seasons, and a secure locking connection for public or exposed charging locations.
