NEMA 6-20 Adapter for Tesla Gen 2 & Gen 3 Mobile Chargers | 16-Inch

NEMA 6-20 Adapter for Tesla Mobile Connector lets your Tesla Gen 2 or Gen 3 Mobile Connector charge from a 240V NEMA 6-20 outlet, the 20A, 240V outlet found in many garages and workshops. It turns that outlet into Level 2 charging at 16A, about four times faster than a standard 120V plug. Its 16-inch length adds reach.

NEMA 6-20 Adapter for Tesla: Key Specs

How It Works

Attach the adapter to your Mobile Connector and plug it into the 6-20 outlet. The adapter tells the connector which outlet it is on, so the car draws 16A, which is 80% of the 20A circuit, as EV charging rules require. If the plug gets too hot, the thermal sensor tells the car to slow or pause charging.

Who It's For

• Garages and shops that already have a 240V 20A outlet
• Drivers who want Level 2 speed without installing a new circuit
• Overnight top-ups of about 120 miles in 8 hours

Before You Buy

• A 6-20 outlet has a horizontal slot, a T-shaped slot and a round ground; it is not the same as a 120V 5-20
• The circuit should be a dedicated 20A, 240V circuit
• Do not use extension cords or stacked adapters
