ChargePoint CT4000
ChargePoint CT4000 is a Level 2 home EV charger from ChargePoint with up to 30 A (8.4 kW) output and a J1772 connector — 18 ft cable, networked smart charging.
Our take
An input-voltage quirk gives this commercial staple the most power in its class: rated at 280 V, its 30 A works out to 8.4 kW and roughly 30 miles of range per hour, versus 7.2 kW for its 240 V cohort-mates — though the count of tracked EVs that can use the full rate slips from 26 to 25. Standby lands exactly mid-pack at 3.7 W, about 33 kWh a year. The compromise is reach: an 18-foot cable is the shortest in the 30 A group against a 24.5-foot median, which can bind at a wide stall. Networked, like the entire cohort, on a 40 A minimum circuit.
- Best for: Commercial sites that can supply its higher-voltage input and want the class’s fastest rate.
- Trade-off: Shortest cable of its cohort at 18 feet.

EV compatibility
The ChargePoint CT4000'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).
