Bigger numbers sell chargers, but the right answer depends on two ceilings: what your home's supply can deliver and what your car's onboard AC charger can accept.
| Setup | Power | Range added per hour | Empty→full (75kWh) |
|---|---|---|---|
| Standard powerpoint | ~2kW | 10–12km | 30+ hrs |
| Single-phase charger | 7kW | 40–50km | ~11 hrs |
| Three-phase charger | 11–22kW | 60–120km | 4–7 hrs |
Many popular EVs cap AC charging at 11kW — some at 7kW. A 22kW charger can't push past your car's onboard limit. Check your vehicle's AC charging spec before paying for three-phase hardware.
For most Sydney households, a smart single-phase 7kW unit on an off-peak tariff is the value pick — it fills the car every night for the least money.
