Which One Actually Fits Your Driving?
Rate alone doesn't decide the winner. IONNA's 32¢/kWh is cheaper than EVgo's 48¢/kWh, but the better network is the one whose stations are where you actually drive. EVgo operates 1,100 stations; IONNA operates 500. Check PlugShare or A Better Routeplanner for your specific corridors before subscribing — a cheaper rate at a network with a station five miles off your route is more expensive than a more costly network at the exit you're already taking.
Membership economics are the other hidden variable. EVgo charges $7.99/month and drops the per-kWh rate to 32¢ — a 16¢/kWh discount. You need to charge roughly 50 kWh per month on EVgo before the subscription pays for itself. Below that, the standard rate is cheaper. IONNA also has no membership plan, so pricing comparisons stay simple.
Connector compatibility is the other decision gate. EVgo supports CCS, CHAdeMO, NACS, while IONNA supports CCS, NACS. If your EV is a 2025+ Tesla, NACS is native. If you drive a pre-2024 Ford, GM, Hyundai, or Kia, CCS is your primary plug — most OEMs are now shipping free NACS adapters to owners. Check your car's connector and which networks support it natively before choosing a home network.
At 15,000 miles per year on a mid-size EV (roughly 50 sessions at a 75 kWh battery), the annual cost difference between IONNA ($960.00) and EVgo ($1,440.00) is $480.00. That's the financial argument. The practical argument still comes down to location coverage and reliability — which varies more by region than any published rate card shows.
