Our verdict
This is the portable we'd suggest to a US J1772 driver with a NEMA 14-50 outlet: it gives the full 40 A (about 9.6 kW) at home, then coils into its carrying case for trips. The manual asks for a dedicated 240 V split-phase or 208 V circuit protected at no more than 50 A, with the outlet installed by a licensed electrician to the NEC and local codes.
The control box is rated IP65 and works from -22 to 122 °F, the cable is 16 ft, and a wall plate is included so it can hang in the garage between trips. It's on the ENERGY STAR list. Lectron's safety notes rule out extension cords and adapters on the outlet side, and if the charger keeps overheating, the manual says to have an electrician check the outlet.
The catch is control. This plug-and-play version has no way to lower the current, so it always offers the car up to 40 A; its Wi-Fi twin (LECHG14-50-40ABLKUS-APP) adds 8 to 40 A steps in the Lectron app. Lectron shows the two-year warranty only as a store-wide badge, and it doesn't state a Canadian safety mark, so we list it for US buyers only.

Lectron Portable Level 2 J1772 EV Charger (40 A, NEMA 14-50) questions
What circuit does the Lectron 40 A portable charger need?
A NEMA 14-50 outlet on a dedicated 240 V split-phase or 208 V circuit, protected at no more than 50 A, according to the manual. Lectron recommends a licensed electrician install the outlet to the NEC and local codes, and local codes win where the two differ.
Can I use it with an extension cord or plug adapter?
No. The manual says not to use it with an extension cord or any AC adapter. Plug it straight into a properly grounded NEMA 14-50 outlet and push the plug fully in so no metal shows on the prongs. If it keeps overheating, have an electrician check the outlet.
Can I lower the charging current?
Not on this plug-and-play version: its manual describes no current setting, so it offers the car up to 40 A. The Wi-Fi version (LECHG14-50-40ABLKUS-APP) lets you pick 8, 12, 16, 24, 32 or 40 A in the Lectron app, connected over Bluetooth or a 2.4 GHz Wi-Fi network.
