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 GB/T 20234.3 (DC) 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.
