Tesla is cheaper for a one-off charge: $0.42–$0.49/kWh at Superchargers versus $0.48/kWh standard at Electrify America. But Electrify America flips the comparison if you charge there even twice a month — its Pass+ membership ($7.99/mo) drops the rate to roughly $0.36/kWh, below almost any Supercharger. The honest answer is: Tesla without memberships, EA with one.
The numbers side by side
| Scenario | Tesla Supercharger | Electrify America |
|---|---|---|
| Standard rate | $0.42–$0.49/kWh | $0.48/kWh |
| With membership | No membership exists (Tesla owners) | ~$0.36/kWh with Pass+ ($7.99/mo) |
| Non-Tesla vehicle | Same rate (+$12.99/mo membership drops it to Tesla-owner pricing) | Same as any vehicle |
| Idle fee | $1.00/min when site is >50% full | $0.40/min after 10-minute grace |
A typical road-trip session of 50 kWh costs about $21–$24.50 at a Supercharger, $24 at EA standard, or roughly $18 at EA with Pass+.
The break-even math
Pass+ pays for itself at about 65 kWh per month — one full charge. Charging a 300-mile trip’s worth monthly at EA? Get Pass+, charge cheaper than Tesla. Passing through EA territory once a quarter? Skip it, and Tesla wins on price.
For non-Tesla drivers, Tesla’s own membership works the same way: $12.99/month drops Supercharger pricing to the Tesla-owner rate, breaking even around two Supercharger sessions a month.
What the per-kWh price hides
Delivered speed changes effective value. EA’s 350 kW hardware outruns Tesla’s 250 kW V3 — but only for 800V vehicles, and EA’s measured session-start reliability still trails Tesla’s. A failed session costs time, which is the real road-trip currency.
