Key takeaways
- Power-sharing chargers split one circuit between two cars.
- Most households can refill two cars overnight with shared power.
- Smart scheduling can stagger charging into off-peak hours.
Option 1: power sharing
Some chargers can be linked so two units share one circuit, dividing the available current between cars. When one car finishes, the other gets the full amount.

Option 2: a dual-port charger
A dual-port unit has two cables on one box. It's simpler to install but both cars must park within reach.
Do the math on your driving
If each car drives 40 miles a day, that's roughly 10–13 kWh each. Even split between two cars, a 40-amp circuit can usually replace that overnight. Use our charging time calculator to check your own numbers.
