Wissandric EV Charger Extension Cable 21FT 50A Level 2 is a heavy-duty, weatherproof J1772 extension cord that extends charging reach while supporting up to 50 amps for faster Level 2 charging.

This 21-foot extension cable from Wissandric is designed to remove placement constraints between your electric vehicle and its charging station. Built with 8 AWG pure copper conductors and a durable rubber jacket, the cord provides stable high-current delivery for J1772-compatible EVs while resisting outdoor elements thanks to an IP66-rated enclosure. It’s intended for homeowners, fleet operators, and anyone who needs extra reach without sacrificing safety or performance.

How does this extension cable improve charging flexibility?

The extra 21-foot length gives you leeway to position your EV or charger without moving the other. Instead of relocating a vehicle or charger, you can bridge awkward distances while maintaining a secure electrical connection.

• 21-foot reach for garages, driveways, and workplace stalls
• Compatible with Level 1 and Level 2 J1772 chargers
• Reduces need to rearrange vehicles or charging stations

Is the cable safe for high-current Level 2 charging?

Yes—the extension uses 8 AWG pure copper conductors rated for 50 amps at 240V, minimizing voltage drop and heat. Components meet UL/ETL safety expectations, and the design emphasizes long-term reliability under regular use.

• 50A capacity supports faster charging compared with lower-amp cords
• 8 AWG copper reduces energy loss and overheating risk
• UL-compliant parts and ETL-tested assembly for dependable operation

Can I use the Wissandric cable outdoors in bad weather?

The extension cord is built to handle outdoor conditions; its reinforced insulation and heavy rubber outer jacket resist moisture, dust, and temperature swings. The IP66-rated plugs and seals help keep water and debris out of critical connections.

• IP66 protection against heavy rain, dust, and splashes
• Flexible jacket maintains pliability in cold and heat
• Rugged strain relief and weatherproof connectors for outdoor use

Will this work with my electric vehicle and charger?

Wissandric’s extension is designed to be universally compatible with SAE J1772-standard plugs, so it pairs with most Level 1 and Level 2 EV chargers and charging ports on non-Tesla vehicles (use Tesla adapter when applicable). It functions as a pass-through extension—no special setup required beyond standard safe connection practices.

• Works with all J1772-compliant EVs and chargers
• Plug-and-play design—no electronics to configure
• Use manufacturer-recommended adapters for vehicle-specific systems

Who is this for: The Wissandric 21FT 50A extension cable is for EV owners and managers who need dependable, longer-reach charging without downgrading amperage or weather resistance. It’s suitable for residential garages, shared parking areas, small commercial fleets, and mobile charging situations where a robust, UL-compliant extension cord is required.
