Overview

• GM introduced a NACS-to-J1772 adapter for Level 2 charging and plans J1772-to-NACS and CCS-to-NACS adapters for future GM models with native NACS ports.
• The new hardware builds on GM’s existing fast-charging adapter program that enables access to Tesla’s Supercharger network.
• GM reaffirmed its plan to shift its EV portfolio to the North American Charging Standard, with native NACS ports slated for the 2026 Cadillac Optiq and the 2027 Chevrolet Bolt.
• The company acknowledged the transition will take time, leaving many drivers to manage multiple dongles to cover home, workplace, and public charging scenarios.
• Most automakers now offer adapters to reach Tesla stations, yet drivers face added complexity and expense, with many adapters priced above $200.
