Frequently Asked Questions

How long does it take to charge a 80 kWh EV battery at 1.4 kW?

Charging a 80 kWh electric vehicle battery from 10% to 80% on a 1.4 kW (120V 12A Level 1 Portable) takes approximately 44h 27m (or 64h 56m for a full 0% to 100% charge including charger efficiency and BMS tapering).

What breaker size is required for a 1.4 kW EV charger?

At 120V (1-Phase), a 1.4 kW charger draws 11.7A continuously, requiring a 15A breaker under US NEC 625.41 (125% continuous load rule) or a 13A breaker under European IEC/NEK standards.
