A 48 amp charger on a 240V circuit delivers 11.5kW — enter your specific battery size to see charging time at this amperage.
Actual charging speed is capped by whichever is lower — this charger's output or your specific EV's onboard charger acceptance rate — check your model's spec if charging seems slower than expected.
A 48 amp circuit at 240V delivers 11.5kW — enough to add a meaningful amount of range per hour for most home charging needs. Actual charging time also depends on your specific vehicle's onboard charger, which has its own maximum acceptance rate regardless of how much power the circuit can deliver — check your model in our EV charging cost calculator or a model-specific page like the Tesla Model 3 calculator for a precise number.
For most daily driving, yes — a 11.5kW charger can fully replenish a typical commute's energy use in just a few hours, comfortably fitting an overnight charging window.
Only up to your vehicle's onboard charger's maximum acceptance rate — beyond that limit, a higher-amperage circuit doesn't speed up charging further, since the vehicle itself caps how much power it will accept.
