Charging Speed
Both chargers deliver identical charging speed at 9.6kW (40A). In practice, this means:
| Vehicle Battery | Grizzl-E Time | JuiceBox Time |
|---|---|---|
| 60 kWh (e.g., Tesla Model 3) | 6.3 hrs | 6.3 hrs |
| 75 kWh (e.g., Tesla Model Y) | 7.8 hrs | 7.8 hrs |
| 100 kWh (e.g., Tesla Model S) | 10.4 hrs | 10.4 hrs |
Since both chargers deliver the same power, charging time is identical. The decision comes down to features and price.
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 JuiceBox’s extra power won’t help.
