For a long-range electric sedan, a Level 2 home charging station in the 40-amp range covers a full overnight charge from a low battery for nearly all daily driving patterns, without requiring the most expensive high-amperage stations.
The charger’s amperage needs to be matched to your home’s electrical panel capacity and the vehicle’s onboard charger rating — buying a station rated well above what your panel or vehicle supports adds cost without adding speed.
| Amperage | Approx. Range Added per Hour | Circuit Requirement |
|---|---|---|
| 24 | ~18 miles/hr | 30A breaker |
| 32 | ~25 miles/hr | 40A breaker |
| 40 | ~30 miles/hr | 50A breaker |
| 48 | ~37 miles/hr | 60A breaker |
Before buying
Have an electrician confirm your panel’s spare capacity before purchasing a high-amperage station — this is the single most common install snag, not the charger itself.
