Detroit automaker's U.S. customers will be able to buy GM-approved NACS DC adapter through vehicle brand's mobile apps.

GM will offer the NACS adapters for $225 through its vehicle brand mobile apps, which can also be used to locate charging stations and pay for charging sessions. They will initially be made available in the United States Wednesday, followed by Canada later this year.

GM says it’s ready to start selling power adapters compatible with Tesla, more than a year after it announced plans to adopt the related charging standard.
