What EV Charger Do You Need for a 2020 Hyundai Kona Electric?
Thirty-two amps is the exact number you need. Your battery takes a maximum charge rate of 7.2 kW on AC power. Plug it into a 40 amp circuit and wake up to a full tank every morning.
The numbers
| Maximum AC charging rate | 7.2 kW (32 A) |
|---|---|
| Charger size to buy | 32 A |
| Circuit breaker required | 40 A |
| Outlet / connection | NEMA 14-50 outlet on a 40 A breaker, or hardwired |
| Charge port | J1772 |
| Full charge on Level 2 | about 9.8 hours |
| Range added per hour (Level 2) | about 26 miles |
| Full charge on a 120 V outlet | about 49 hours |
| Range added per hour (120 V) | about 5.2 miles |
| EPA rated range | 258 miles |
| Energy for a full charge | about 70.9 kWh at the wall |
Why 32 amps and not more
Your onboard charger tops out at 32 amps. Buying a larger 40 or 48 amp supply wastes money because the car cannot pull the extra current. Electricity flows into the 70.9 kWh battery at 26 miles of range per hour on a Level 2 setup. The EPA test logs 29 miles per hour because their specific laboratory drive cycles measure energy slightly differently. Feeding the vehicle more power changes nothing about how fast the pack fills up.
What the install involves
You need a NEMA 14-50 outlet on a 40 amp breaker, or you can hardwire the unit directly to your electrical panel. Hire a licensed electrician for this work. They pull permits, size the copper wire correctly, and verify your home service panel handles the continuous load safely. Local building codes dictate the exact conduit and breaker specifications for your garage.

Common questions
- Can I use a standard wall outlet?
- Level 1 charging on a standard household outlet takes 49 hours for a full refill. You get 5.2 miles of range per hour this way, which is too slow for daily commuting.
- What plug does the car use?
- The vehicle uses a J1772 connector for AC Level 2 charging. Every non-Tesla EV sold in North America through 2024 uses this exact standard.
- How long does a full charge take?
- A complete fill from empty takes 9.8 hours at the maximum Level 2 rate. The EPA test estimates 9.0 hours based on their specific laboratory testing parameters.
- What equipment works with this car?
- Units like the Autel MaxiCharger AC Lite 40A, Grizzl-E Classic 40A EV Charger, and Wallbox Pulsar Plus 40A all deliver the correct amperage. They plug into a NEMA 14-50 outlet and supply the 32 amps your vehicle demands.
