Charging Speed
The Wallbox Pulsar Plus wins on raw charging speed with 11.5kW (48A) versus 9.6kW (40A). In practice, this means:
| Vehicle Battery | JuiceBox Time | Wallbox Time |
|---|---|---|
| 60 kWh (e.g., Tesla Model 3) | 6.3 hrs | 5.2 hrs |
| 75 kWh (e.g., Tesla Model Y) | 7.8 hrs | 6.5 hrs |
| 100 kWh (e.g., Tesla Model S) | 10.4 hrs | 8.7 hrs |
The 1.9kW difference translates to about 1.3 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, the Wallbox’s extra power won’t help.
