SEGUMA NACS to CCS1 Charging Adapter — 500A 250 kW DC Fast, 1000V with Thermal Safety

If you drive a CCS1-standard EV and want reliable access to the Tesla Supercharger network, this SEGUMA adapter bridges CCS1 to the NACS inlet. Built for high-current DC fast charging, it is engineered to handle up to 500 amps and 1000 volts while prioritizing safety features like temperature monitoring and dual-locking connectors. The adapter expands public charging options by permitting CCS1 vehicles (that have authorized Tesla Supercharger access) to use compatible NACS fast chargers.

How fast can this adapter charge my EV?

The adapter supports peak charging capability up to 500A and 250 kW when both your vehicle and the Supercharger can deliver those rates. Actual range added in 15 minutes depends on station output, vehicle acceptance rates, battery state and temperature.

• Maximum specification: 500A / 1000V / 250 kW.
• Example pace: up to ~180 miles in 15 minutes under ideal conditions (real results vary).
• Charging rate adjusts automatically with thermal and vehicle limits.

Which cars work with the SEGUMA NACS to CCS1 adapter?

This adapter is made for CCS1-equipped vehicles that have been granted access to Tesla’s Supercharger network. It supports many North American CCS1 brands but does not universally support all models or every manufacturer.
