Properly, AoG has Pentecostal roots, but is under the broader umbrella of "Charismatic." Pentecostals are a distinct denominational group(s).

Interestingly, the Wesley's of Methodism are the true pioneers of this movement.

[Anitius Severinus Boethius]

The Assemblies of God considers themselves a Pentecostal movement. Charismatic usually refers to a movement within a non-Pentecostal founded church (e.g. Charismatic Catholics, Charismatic Lutherans) or a movement or denomination that came out of a non-Pentecostal based church.
