The BMW i4 is equipped with a Flexible Fast Charger compatible with any 120V or 240V outlet. A 240V outlet will typically charge your all-electric BMW from 0% to 100% in under 12 hours. The standard North American charging system is CCS (DC Fast Charging) and J1772 (Level 2 charging). The BMW i4 can charge on all public charging stations with a CCS or J1772 plug.
