SemaConnect
SemaConnect is a Level 2 home EV charger from SemaConnect with up to 80 A (19.2 kW) output and a J1772 connector — 18 ft cable, networked smart charging.
Our take
The trade here is reach for idle efficiency: an 18-foot cable in the bottom quarter of the 80 A class, against 2.71 W of standby in the 14th percentile of the 65 certified models — about 24 kWh a year, well under the median. Output is the class-standard 19.2 kW on a minimum 100 A circuit, and it carries the Wi-Fi connectivity found on 94% of the cohort. Measure the parking geometry before committing to the shorter cable.
- Best for: Close-quarters installs that value a top-15% idle figure.
- Trade-off: Seven feet less cable than the class median.

EV compatibility
The SemaConnect's J1772 connector plugs directly into 23 of the 29 EVs tracked in this database. The other 6 (Hyundai Ioniq 5, Tesla Cybertruck, Tesla Model 3, Tesla Model S, Tesla Model X, Tesla Model Y) work with it too — requires a J1772-to-NACS adapter (Tesla includes one with its vehicles).
