Charging Speed
The Autel MaxiCharger Home 50A wins on raw charging speed with 12kW (50A) versus 11.5kW (48A). In practice, this means:
| Vehicle Battery | Autel Time | Siemens Time |
|---|---|---|
| 60 kWh (e.g., Tesla Model 3) | 5.0 hrs | 5.2 hrs |
| 75 kWh (e.g., Tesla Model Y) | 6.3 hrs | 6.5 hrs |
| 100 kWh (e.g., Tesla Model S) | 8.3 hrs | 8.7 hrs |
The 0.5kW difference translates to about 0.3 hours faster on a 75 kWh battery — noticeable but not dramatic for overnight charging.
Important: Most EVs have an onboard charger that caps AC charging speed (typically 11-11.5 kW). If your car maxes out at 11 kW, both chargers will charge at the same rate regardless.
