Both the myenergi zappi (7kW / 22kW) and NexBlue Edge (7.4kW / 22kW) support three-phase charging, offering up to 22kW on a three-phase supply. On a standard UK single-phase supply, both deliver around 7kW — more than enough for overnight charging.

On a standard UK single-phase supply, both will charge a Tesla Model 3 Long Range (75kWh battery) from 20% to 80% in approximately 5–6 hours overnight. Even a Tesla Model Y with its larger battery completes a typical daily top-up well within an overnight window. For the vast majority of UK Tesla owners, single-phase 7kW charging is more than sufficient — you'll wake up to a full battery every morning.
