how many kilowatts does it take to charge a tesla

You don’t “use” a fixed number of kilowatts to charge a Tesla—kilowatts are charging power, not the energy going in.

At home, a standard 10A socket delivers about 2.3 kW, a 15A outlet ~3.6 kW, a dedicated single‑phase wallbox around 7.4 kW, and three‑phase up to 11 kW (your car’s onboard charger is the ceiling).

Public AC posts usually sit at 7–22 kW, while common DC fast chargers are about 50 kW.

Tesla Superchargers in Australia typically peak between 150 and 250 kW on compatible models with warm batteries.

Energy added is measured in kWh and roughly tracks battery size—think ~55–75 kWh for many Model 3/Y variants.

Key figures: 2.3–11 kW AC at home, ~50 kW DC fast, ~150–250 kW Supercharging. Consult official documentation for exact figures.
