Expert ScoreRead review

The Enphase 32 Amp Plug-in EV Charger (HCS-40) with NEMA 14-50 plug offers 7.7kW power for fast, reliable charging. Featuring a durable 25 ft cable and J1772 ruggedized connector, it ensures compatibility with all EVs. Backed by a 5-year warranty, this charger provides robust, long-term performance for home use.

The Enphase HCS-40 Level 2 EV Charger offers reliable and fast charging with a simple installation process. This charger features a 5-year limited warranty and 24/7 customer support, making it a trustworthy option for EV owners. Its durable design ensures long-lasting performance, while the NEMA 14-50R plug allows for easy setup on a 40 Amp dedicated circuit.

This charger meets ETL safety certifications and is ENERGY STAR-rated. Built to withstand high-traffic use and extreme temperatures, it’s perfect for both home and commercial environments. The NEMA 4 weather-resistant enclosure protects internal components from moisture, ensuring consistent performance in various outdoor conditions.

With a 7.7 kW output, the HCS-40 charges up to 7 times faster than standard Level 1 chargers. Depending on your vehicle, it can add up to 31 miles of range per hour. It works well with all plug-in EVs in the USA, especially those with charging rates up to 7.7 kW like the Tesla Model 3, Jeep Wrangler 4xe, and Hyundai Kona.

The charger includes a 25-foot cable and a J1772 connector, allowing for flexible placement in your garage or driveway. It also features a cable wrap and wall-mounted holster for easy storage after use. While it may be on the pricier side, the quality, safety features, and integration with solar systems (if applicable) make it a solid choice. Plus, it fits seamlessly into the Enphase ecosystem, offering the convenience of managing everything through one app.

Though the rubberized cord can be difficult to manage and prone to tangling, the overall value and peace of mind from using a safe, fast charger outweigh this minor inconvenience.
