Frequently Asked Questions
How much power can this adapter handle?
It is rated 300 A continuous (400 A peak) at up to 1000 V DC - roughly 250-300 kW with a compatible high-power charger. Actual power is negotiated between the vehicle and the station.
Which vehicles does it fit?
NACS (Tesla J3400) on one side and CHAdeMO on the other. Confirm your charge port and the charger standard before ordering.
Does it support vehicle-to-load or AC charging?
No. This is a DC fast-charging adapter. For AC cross-standard charging, see our /ac-adapters collection.
