Ionna charging questions
- How much does Ionna charging cost per kWh?
- WattWay prices Ionna at about $0.39/kWh for DC fast charging, which makes it the 4th cheapest of the 16 networks it tracks (tied with 1 other at the same rate) and below the $0.43/kWh average by $0.04 per kWh. Actual rates vary by site, time of day and local taxes; when a station publishes its own price, the planner uses that instead.
- Is Ionna expensive compared with other networks?
- Across the networks WattWay prices, rates run from $0.20/kWh (OUC) to $0.59/kWh (Blink). At $0.39/kWh, Ionna sits toward the cheap end. On a 500-mile trip, the charging you buy en route differs by roughly $4.22 versus an average-priced network for a mid-size EV.
- Does Ionna have a membership or subscription?
- WattWay doesn't model a subscription for Ionna, so no membership discount is applied to its sessions. That does not mean every stop is priced at $0.39/kWh: when a station publishes its own rate through Open Charge Map the planner uses that, and this reference rate is only the fallback for stations that don't. If the network introduces a plan worth modeling it will be added to the planner's membership list.
