Public Charging Networks Compared: Tesla, Electrify America, EVgo & ChargePoint
How each network charges you
Tesla Superchargers: per-kWh pricing that varies by site and time (roughly 25–50¢), famously reliable, open to many non-Teslas via NACS — non-Tesla drivers often pay a premium unless they take the monthly membership. Electrify America: the guest rate commonly sits near 48–64¢/kWh, with a modest monthly membership (~$7) cutting roughly 25% — do the math at your usage. EVgo: typically 39–59¢ depending on plan, region and time of day, with tiered memberships that reward regulars. ChargePoint: mostly a platform — the property hosting the charger sets pricing, so you'll meet everything from free-with-parking to painful; always check the app before assuming.
Prices shift often and by location — treat these as the shape of each network's pricing, and the session screen as the truth.
The fee traps
Idle fees: most networks bill per minute once charging completes and the car sits (commonly 40¢–$1/min) — set the app's alerts and move the car. Session and connection fees: some stations add a flat $1 or so per session; irrelevant on a big charge, brutal on a 10-minute top-up. Per-minute billing (still used at some stations and states): punishes cars that charge slowly — a cold battery or an 80%+ state of charge means paying full rate for a trickle. And guest-vs-member spreads on some networks are large enough that skipping a free signup literally costs money.
Choosing without tribalism
Road-tripping any NACS-equipped car: Tesla's network wins on reliability and density along corridors — this is the closest thing US charging has to a default. Regular fast-charging in a metro without home power: compare EVgo and Electrify America membership math against your monthly kWh; whichever has the closer, more reliable sites to your life wins, and the membership pays for itself fast at even one session a week. Errand-time Level 2: ChargePoint's host-priced world is where free and cheap charging hides — the app's filters find it.
Universal advice regardless of badge: install all the major apps before you need them, check recent user check-ins for broken stalls, and let our calculator translate any network's per-kWh price into cost-per-mile so you can compare it to gas in one glance.
FAQ
Which EV charging network is cheapest?+
ChargePoint's host-set Level 2 sites can be cheapest (sometimes free); among fast-charging networks, membership pricing at EVgo or Electrify America usually undercuts guest rates by 20–30%, and Tesla is often the value-and-reliability pick for NACS cars. Location beats brand — check the app.
Are charging network memberships worth it?+
At one fast-charge session a week or more, almost always — the ~$7 memberships typically pay back with 25%-ish discounts. Occasional users should stay on guest rates and skip subscription creep.
Why did my charging session cost more than the advertised rate?+
Usually idle fees after the charge finished, a session fee, taxes, or per-minute billing while your car charged slowly. The receipt breakdown in the app tells you which — and the fix (alerts, timing, fuller sessions) follows from it.
