Practical Notes: i4 on IONNA
The i4's CCS port plugs directly into IONNA's CCS stalls without an adapter. Check the IONNA app before your first session to confirm which connector your target station uses — mixed-connector deployments are common in 2026.
On a session-by-session basis, the i4's 205 kW peak charging speed is well-matched to IONNA's DC fast hardware. Expect a 10→80% charge in roughly 14 min. Real-world times run 10–20% longer due to charging taper and battery preconditioning.
Cost-wise, one $21.48 full charge on IONNA represents $0.07 per mile of driving — about 6.8¢/mile. A gas equivalent at 30 mpg and $3.50/gal is roughly 11.7¢/mile, so this charging session is still cheaper than gas. Over 15,000 miles/year, exclusive reliance on IONNA would cost roughly $1,266.42/year in fuel — a meaningful delta compared to mostly-home charging (~$653.00/year).
For most i4 owners, the realistic use-pattern for IONNA is road trips and occasional top-ups — not primary fueling. If you live in an apartment or condo and rely on public charging as your main option, factor in the per-session pricing with no membership option. For regular home charging in a specific state, check our home vs public analysis and your i4 state-by-state breakdown.
