Lectron 40 A - Level 2 J1772 Smart Portable EV Charger Review and Product Manual

The lectron 40 A - Level 2 J1772 Smart Portable EV Charger is a compact, Wi-Fi-enabled home and travel charging solution designed for EV drivers who want faster charging without installing a permanent wall unit. It delivers up to 40 amps at 240 volts, supporting charging speeds of up to 9.6 kW when paired with a compatible 50-amp circuit and a NEMA 14-50 outlet. That makes it a practical choice for overnight charging, daily commuters, and drivers who need a portable charger they can bring between home, work, and road-trip destinations.

One of its biggest advantages is the smart app control, which lets users monitor charging status, schedule sessions, and adjust charging settings from a smartphone. The charger is widely described as compatible with most SAE J1772 EVs and plug-in hybrids, including many models from Ford, Honda, Nissan, Volkswagen, BMW, Hyundai, Kia, and others. A Tesla driver can also use it with an adapter. The 16-foot cable, IP-rated weather resistance, and rugged build make it suitable for garage use and light outdoor exposure. The device is also positioned as a strong value option, with reported pricing typically around $230 to $300, depending on the retailer and promotions.

For buyers comparing portable EV chargers, this model stands out as a smart portable EV charger that combines Level 2 speed, app-based control, and a travel-friendly form factor. It is especially appealing to users who want a reliable J1772 EV charger for home charging, backup charging, or shared charging setups.

How to Set Up the Lectron 40 Amp Level 2 J1772 Smart Portable EV Charger

To begin setup, first confirm that your outlet matches the charger’s plug type, typically a NEMA 14-50 receptacle on a properly rated circuit. Next, mount the included wall bracket if you want a semi-permanent garage installation, or keep the unit portable for travel use. Plug the charger into the outlet, then connect the J1772 handle to your EV’s charging port. If your vehicle uses a different connector, use the proper adapter before starting a session.

For smart features, scan the QR code in the manual or package insert, download the Lectron app, and pair the charger to your phone over Wi-Fi or Bluetooth. In the app, you can set charging schedules, view energy usage, and select charging current settings when supported by the unit. Common current options include 40A, 32A, 24A, 16A, 12A, and 8A, which helps match the charger to different electrical setups and driving needs.

Before use, inspect the cable, plug, and connector for damage. Do not use extension cords, and never operate the charger with a loose or overheated outlet. If the unit does not connect, restart the app, check Wi-Fi signal strength, verify that the outlet is energized, and make sure the vehicle is fully plugged in. For safety, always follow the circuit rating, keep the charger dry when possible, and avoid charging if you notice unusual heat, smell, or visible wear.
