GM Adds Three EV Charging Adapters as NACS Transition Deepens

The new dongles expand access across mixed charging hardware during the industry's shift to Tesla's plug standard.

Overview

  • GM introduced a NACS-to-J1772 adapter for Level 2 charging, a J1772-to-NACS adapter for Level 2 on future NACS-port GM EVs, and a CCS-to-NACS adapter for DC fast charging.
  • The additions build on GM’s previously released NACS-to-CCS fast-charging adapter that enables existing GM EVs to use Tesla Superchargers.
  • GM reiterated plans to move its EV lineup to the Tesla-style connector, with the 2026 Cadillac Optiq and 2027 Chevrolet Bolt confirmed and no timeline for other models.
  • During the transition, owners may juggle multiple dongles, and many adapters cost more than $200, raising short-term complexity and expense.
  • Technical differences between connector designs require separate solutions for Level 2 and DC fast charging, though most charging occurs on predictable home or workplace equipment.
