RAB EVC40
RAB EVC40 is a Level 2 home EV charger from RAB with up to 40 A (9.6 kW) output and a J1772 connector — 15 ft cable, non-networked operation.
Our take
Fifteen feet of cable is the defining constraint — shorter than about 90% of the 56 certified 40 A models in this database and nine feet under the cohort median, which effectively limits this unit to mounting within arm’s reach of the charge port. It is also one of the minority of offline units in a 77% networked class. The electrical basics are all present: 9.6 kW on a minimum 50 A circuit, roughly 34 miles of range added per hour, full-rate charging on 25 of our 29 tracked EVs, and a 2.46 W standby draw sitting near the 2.38 W class median.
- Best for: Tight single-bay installs where the unit mounts directly beside the charge port.
- Trade-off: One of the shortest cables in the class, with no connectivity.

EV compatibility
The RAB EVC40'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).
