Tesla Superchargers substantially outperform Level 2 chargers in reliability, though direct comparisons between DC fast chargers and Level 2 chargers require context:
Tesla Supercharger Reliability
- 3.9–4% issue rate: Consumer Reports and JD Power studies show Tesla Superchargers have charging problems in just 3.9–4% of sessions, making them the most reliable EV charging network.
- Non-Tesla DC fast chargers: These had a 34% reported issue rate, while Level 2 chargers (non-Tesla) were more reliable than fast chargers at 25% issues.
Key Comparison
| Charger Type | Reported Issue Rate |
|---|---|
| Tesla Supercharger | 3.9–4% |
| Non-Tesla DC Fast | 34% |
| Level 2 Chargers | 25% |
While Level 2 chargers are generally more reliable than non-Tesla DC fast chargers, Tesla Superchargers are 6–8 times more reliable than Level 2 chargers overall. Recent data (Q1 2025) shows overall DC fast charging reliability improving to ~82.6% success rates (17.4% failure rate), though this aggregates all networks and still lags behind Tesla’s performance.
