Cost to Charge Volkswagen ID.4 on IONNA

The ID.4'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 ID.4's 135 kW peak charging speed is well-matched to IONNA's DC fast hardware. Expect a 10→80% charge in roughly 20 min. Real-world times run 10–20% longer due to charging taper and battery preconditioning.

Cost-wise, one $20.99 full charge on IONNA represents $0.07 per mile of driving — about 7.2¢/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 $1,352.58/year in fuel — a meaningful delta compared to mostly-home charging (~$697.42/year).

For most ID.4 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.
