What EV Charger Do You Need for a 2023 Kia Niro Electric?
Plugging into a Level 2 setup refills the battery in 6.7 hours. That turnaround easily handles overnight top-offs from a drained pack. You need a 48 amp EVSE to hit that speed. Anything smaller leaves capability on the table.
The numbers
| Maximum AC charging rate | 11.0 kW (48 A) |
|---|---|
| Charger size to buy | 48 A |
| Circuit breaker required | 60 A |
| Outlet / connection | hardwired (a 48 A EVSE must be hardwired -- no household receptacle is rated for it) |
| Charge port | J1772 |
| Full charge on Level 2 | about 6.7 hours |
| Range added per hour (Level 2) | about 38 miles |
| Full charge on a 120 V outlet | about 51 hours |
| Range added per hour (120 V) | about 4.9 miles |
| EPA rated range | 253 miles |
| Energy for a full charge | about 74.0 kWh at the wall |
Why 48 amps and not more
The car accepts up to 48 amps on AC power. Feeding it fewer amps stretches the refill time needlessly. Buying a 48 amp charger matches the onboard capacity directly. If you hook this vehicle up to a larger 50 amp unit, the car still draws its maximum limit of 48 amps. Extra charger capacity does nothing here.
What the install involves
A 48 amp draw requires a 60 amp breaker. Hardwiring is mandatory because household receptacles cannot handle this continuous load safely. Never plug a 48 amp unit into a wall outlet. Hire an electrician to run the heavy-gauge copper wiring and mount the hardware directly to the wall.
Chargers that match this car
Energy monitoring built in. Hardwire it for the full 48 A.
Compact unit, good for tight garages.
Adjustable from 16 A to 50 A in the app, which helps if your panel is tight.

Common questions
- What plug does the car use?
- It uses a standard J1772 connector for all AC Level 2 charging. This plugs directly into the port without adapters.
- How long does a standard wall outlet take?
- Level 1 charging takes 51 hours for a full tank. That yields 4.9 miles of range per hour.
- Why does the EPA test show 7.5 hours?
- The EPA testing protocol does not always run at the absolute peak AC rate of the vehicle. Real-world max charging finishes in 6.7 hours.
- Can I use an adjustable charger?
- Yes, units like the ChargePoint Home Flex let you dial down the amperage in the app. This helps if your home electrical panel has limited remaining capacity.
