My Experience with the WOLFBOX Level 2 EV Charger 40 Amp

Installing the WOLFBOX 40 Amp charger was straightforward with clear instructions. The charger plugged into a standard NEMA 14-50R outlet, and setup through the WOLFBOX app was intuitive. The 4.3-inch LCD screen clearly displays charging rate, voltage, time elapsed, and energy delivered, which is helpful for tracking charging sessions without opening the app.

Wi-Fi connectivity allowed me to adjust charging current, schedule charging to avoid peak rates, and monitor the session remotely. The charger integrates well with Alexa and Google Assistant for voice commands, enhancing smart home compatibility. Sharing control among multiple household members was seamless, adding convenience.

Charging performance was solid and consistent, providing a steady 40 amps without overheating or interruptions. Compatibility with all J1772 vehicles is a plus, though Tesla owners will need a dedicated WOLFBOX J1772-to-Tesla adapter to use this charger.
