IONNA Price Per kWh, Coverage & Membership

IONNA charges 32¢/kWh as its standard per-kWh rate. For a Tesla Model 3 or similar 75 kWh EV, an 80% top-up costs $19.20 — adding roughly 280 miles of range. IONNA has no paid tier; all drivers pay the same published rate.

Real-world pricing deviates from the published rate for three reasons. First, location: IONNA rates can vary by station, especially at premium sites or airports. Second, peak demand: some sites add congestion pricing during busy hours. Third, idle fees: most networks charge $0.40–$1.00/minute if you stay plugged in past full charge, which can add several dollars if you're inattentive. Always check the app price before you plug in.

On a DC fast charger, the 400 kW peak speed is only hit during a narrow window of the charging curve — typically between 10% and 50% state of charge. From 50% to 80%, charging speed tapers significantly. This is why most EV owners stop charging around 80% on road trips: the last 20% can take as long as the first 60%. The $19.20 estimate above assumes the network bills cleanly per kWh delivered; if your state bills per-minute instead, taper can inflate the effective cost by 10–20%.

Compare IONNA against home charging: at the national residential average of 16.5¢/kWh, a 75 kWh full charge costs $9.90 — about $9.30 less than charging at IONNA. Over 50 sessions a year, that's a difference of $465.00. For most drivers, this is the strongest argument for installing a home Level 2 charger (about $500–$1,500 installed) if you own your home. For renters and road trippers, IONNA's 500 stationsis what you're paying for — reliability and geographic reach, not just electricity.
