Charging Speed
The ChargePoint Home Flex wins on raw charging speed with 12kW (50A) versus 9.6kW (40A). In practice, this means:
| Vehicle Battery | ChargePoint Time | JuiceBox Time |
|---|---|---|
| 60 kWh (e.g., Tesla Model 3) | 5.0 hrs | 6.3 hrs |
| 75 kWh (e.g., Tesla Model Y) | 6.3 hrs | 7.8 hrs |
| 100 kWh (e.g., Tesla Model S) | 8.3 hrs | 10.4 hrs |
The 2.4kW difference translates to about 1.6 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 ChargePoint’s extra power won’t help.
