What EV Charger Do You Need for a 2020 Hyundai Ioniq Electric?
You need a 32 amp Level 2 home charging setup for this car. The onboard charger caps your intake at 7.2 kW. Buying a bigger unit wastes money because the vehicle cannot accept higher speeds.
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 6.0 hours |
| Range added per hour (Level 2) | about 28 miles |
| Full charge on a 120 V outlet | about 30 hours |
| Range added per hour (120 V) | about 5.7 miles |
| EPA rated range | 170 miles |
| Energy for a full charge | about 43.2 kWh at the wall |
Why 32 amps and not more
Matching the 32 amp onboard limit lets you push 28 miles of range into the battery every single hour. A larger 40 amp or 48 amp EVSE costs more cash up front. Your car draws its maximum 32 amps and leaves the extra circuit capacity sitting idle. The battery capacity totals 43.2 kWh. Feeding it at 7.2 kW brings the pack from empty to full in 6.0 hours.
What the install involves
Have a qualified electrician pull a circuit for a NEMA 14-50 outlet on a 40 A breaker. Hardwiring the unit directly to the wall works fine too. The electrician must check your main panel to verify spare capacity before landing any wires. Never skip the breaker sizing step because 40 amps requires heavy gauge copper wiring to prevent dangerous heat buildup.

Common questions
- Can I plug this car into a standard wall outlet?
- Yes, standard Level 1 charging works on a household 120 V outlet. Expect a crawl speed of 5.7 miles per hour. A full recharge takes 30 hours.
- What plug type does the car use?
- The charge port uses a J1772 connector. Every non Tesla EV sold in North America through 2024 uses this standard for AC Level 2 charging.
- Will a 40 amp charger charge my car faster than a 32 amp charger?
- No. The car maxes out at 32 amps. A 40 amp Grizzl-E Classic or ChargePoint Home Flex will still deliver power at the exact same speed.
- Can I use Tesla destination chargers?
- Yes, if you buy a compatible adapter like the Lectron Tesla to J1772 Charging Adapter. It handles up to 80 amps.
