Design and Build Quality

Upon handling the Lectron adapter, its sturdy construction stands out. While reminiscent of the older version of the TeslaTap in size, its more extensive profile ensures visibility, particularly in public charging stations. However, its design is well-suited for private usage, such as home garages.

It features a pigtail-style design with a short power cord, consisting of a Tesla female socket on one end and a J1772 male socket on the other. The total length is 17.2 inches, adding reach to a charging cord. The adapter comprises a Tesla adapter and charging head connected by a 4″ cable, available in two colours.

The charging head’s ribbed surface provides a comfortable grip, enhancing the user experience. Although disconnecting from the Tesla connector requires more effort for safety reasons, the snug fit ensures secure connections without hindering charging mechanisms.

The adapter is available in two variants, featuring a black cord. However, customers can choose between black or white sockets and plugs.

Usability and Performance

The plug-and-play simplicity of the Lectron adapter streamlines the charging process. The adapter maxes out at 48 amps with any 240-volt Tesla charger, except for the Tesla Supercharger, which outputs 480 volts; we tested the adapter on the Tesla High Power Wall Connector on a standard double pole 60 amp circuit breaker, Destination Charger, and Mobile Connector.

Charging speeds for the Lectron Tesla to J1772 adapter vary depending on numerous factors. These include the Tesla charger type, the charged EV on-board charger, battery level, cable specifications, and ambient temperature. While the adapter supports a maximum power output of 11.5kW, translating to around 25 miles per hour of charging, real-world speeds typically range between 10 and 20 miles per hour.

The adapter maintains a cool temperature during operation, indicating reliable contact and efficient performance. Users have reported high compatibility with many electric vehicles, including less popular models, enhancing its appeal and utility.

While the adapter does not have an official IP rating, it works fine in the rain, with rubber plugs to cover the openings at each end.

Using the Lectron Tesla to J1772 Adapter

During our usage of the Lectron Tesla to J1772 Adapter, several unexpected findings emerged, shedding light on the nuances of its operation and ensuring optimal performance.

Ensuring Proper Connection

Achieving a secure connection with the Tesla Tap proved to be challenging due to the adapter’s tight fit. Utilizing dielectric grease on the pins can facilitate smoother seating, enhancing the overall user experience.

Sequential Connection Process

For seamless charging, it’s imperative to connect the adapter to the Tesla destination charger first and then wait approximately 10 to 30 seconds for the charger to detect the adapter before linking it to the vehicle. This brief delay ensures successful charging initiation.
