Our verdict
For a Tesla or other NACS-port EV and a NEMA 14-50 outlet, this is a simple way to get full Level 2 speed from a cord rather than a wall unit. It's the same 40 A design as Lectron's J1772 portable with a NACS handle, and Lectron lists the Tesla Model S, 3, X, Y and Cybertruck. The manual asks for a dedicated 240 V split-phase or 208 V circuit, with the outlet installed by a licensed electrician to the NEC and local codes.
The rest matches the J1772 twin: a 16 ft cable, an IP65 control box rated from -22 to 122 °F, a wall plate, and a place on the ENERGY STAR list. The manual warns against non-approved power adapters and asks for a properly grounded outlet with the plug pushed fully in.
The catches: this version has no current setting (the Wi-Fi twin, LECHG14-50-40ATSLBLKUS-APP, adds 8 to 40 A steps in the Lectron app), and its manual gives no breaker size, so have the electrician confirm the circuit. The two-year warranty appears only as a store-wide badge. Lectron doesn't say whether its ETL mark covers Canada, so we list it for US buyers only.

Lectron Portable Level 2 Tesla (NACS) EV Charger (40 A, NEMA 14-50) questions
Which cars can use the Lectron NACS portable charger?
Cars with a NACS (SAE J3400) charge port. Lectron lists the Tesla Model S, 3, X, Y and Cybertruck and other EVs with a NACS port. It isn't for J1772-port cars; Lectron makes a J1772 version of the same 40 A cord for those.
What outlet does it need?
A properly grounded NEMA 14-50 outlet on a dedicated 240 V split-phase or 208 V circuit. Lectron recommends a licensed electrician install it to the NEC and local codes. This manual gives no breaker size, so ask the electrician to confirm the circuit before you plug in.
