Charging Speed

The Enel X JuiceBox 48A wins on raw charging speed with 11.5kW (48A) versus 9.6kW (40A). In practice, this means:

Vehicle BatteryJuiceBox TimeEnel X Time
60 kWh (e.g., Tesla Model 3)6.3 hrs5.2 hrs
75 kWh (e.g., Tesla Model Y)7.8 hrs6.5 hrs
100 kWh (e.g., Tesla Model S)10.4 hrs8.7 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 Enel X’s extra power won’t help.
