What EV Charger Do You Need for a 2025 Kia Niro Electric?
Many home chargers can pump out 50 amps, but your car maxes out at 48 amps. You need a 48-amp Level 2 charger to hit the peak charging speed. Plug it in, and the battery goes from empty to full in 6.9 hours. You get 37 miles of range for every hour plugged in.
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 6.9 hours |
| Range added per hour (Level 2) | about 37 miles |
| Full charge on a 120 V outlet | about 53 hours |
| Range added per hour (120 V) | about 4.8 miles |
| EPA rated range | 253 miles |
| Energy for a full charge | about 75.9 kWh at the wall |
Why 48 amps and not more
Your car accepts 11.0 kW of AC power through its onboard charger. Pushing more than 48 amps from a larger unit does zero good because the car regulates its own intake. Buy a 48-amp EVSE to feed the vehicle at its absolute limit. Anything smaller leaves speed on the garage floor. The battery holds 75.9 kWh, so matching the max amperage is the only way to turn around a dead pack in under seven hours.
What the install involves
A 48-amp draw requires a dedicated 60-amp circuit breaker in your electrical panel. Do not look for a wall outlet. This setup demands hardwiring because household receptacles melt under continuous loads that high. Call an electrician to run heavy gauge wire from the panel straight to the charger. Safety rules dictate hardwiring for any continuous 48-amp load.

Common questions
- How long does a standard wall outlet take?
- Level 1 charging on a standard household plug takes 53 hours to fill the battery. You only gain 4.8 miles of range per hour of charging. It is too slow for daily commuting.
- Why does the EPA charge time differ from the max rate?
- The EPA test takes 7.5 hours and yields 34 miles per hour of charge. Standard compliance testing does not always run at the car's peak AC rate. Real-world max charging hits 6.9 hours.
- What plug connector does this car use?
- The car uses a J1772 connector. Many 2025+ vehicles ship with a NACS port but include a J1772 adapter, so a J1772 home charger still works. Confirm your car's port before buying.
- Can I use a 50-amp charger like the ChargePoint Home Flex?
- Yes. The ChargePoint Home Flex adjusts down to your car's limit or runs at 50 amps, though your car only pulls 48 amps max. Always match the circuit breaker to the configured amperage.
