Best EV Charger for Hyundai IONIQ 6 Long Range
We recommend the ChargePoint Home Flex hardwired EV charger as the top choice for the Hyundai IONIQ 6 Long Range due to its superior fast charging capabilities compared to the plug-in version. However, if portability is a priority, the ChargePoint Home Flex Plug-in charger is an excellent option for the Hyundai IONIQ 6.
Charge Point Home Flex EV Charger Review
The hardwired ChargePoint Home Flex Level 2 EV charger offers adjustable amperage up to 48A, meeting the IONIQ 6’s maximum onboard charging capacity of 11 kW. When connected to a 240V, 60A circuit, it can fully charge the 77.4 kWh IONIQ 6 Long Range lithium-ion battery in under 7.5 hours.
In comparison, the plug-in ChargePoint Home Flex Level 2 EV charger offers an adjustable amperage of up to 40A, delivering 9.6kW optimized for circuit compatibility and component support, per NEC rules. This is approximately 14.56% lower in power output than the IONIQ 6’s maximum onboard charging capacity of 11kW on a 240V, 60A circuit. As a result, the plug-in charger takes about 1.5 hours longer, fully charging the battery in 9 hours.
| Feature | ChargePoint Home Flex (Hardwired) | ChargePoint Home Flex (Plug-in) |
|---|---|---|
| Amperage | Adjustable up to 48A | Adjustable up to 40A |
| Circuit Requirement | 240V, 60A circuit | 240V, 50A circuit |
| Charging Speed | Up to 11kW | Up to 9.6kW |
| Battery Charge Time (77.4 kWh) | 7.5 hours | 9 hours |
| Installation Type | Hardwired | Plug-in (with NEMA 14-50 or NEMA 6-50 outlet) |
Both chargers deliver reliable performance under continuous 7+ hour loads, maintaining approx 94% to 95% EV charging efficiency, without throttling or significant performance drops. Based on our tests, the main difference is the charging time.

ChargePoint Home Flex Performance on Hyundai IONIQ 6 Long Range
To evaluate the real-world charging performance of the ChargePoint Home Flex, we conducted a 28-day test using a rented Hyundai IONIQ 6 Long Range (EPA-estimated 342-mile range).
Our analysis included the use of professional tools such as the Autel MaxiSys Ultra EV OBD2 Scanner for onboard battery diagnostics, the ChargePoint Mobile App for energy consumption monitoring, distance tracking, and setting reminders, and an independent meter-based system for measuring energy delivery to the circuit, monitoring efficiency, and verifying billing accuracy.
Our daily driving varied between 150 and 250 miles, except on the first and last days when we drove 50 miles to pick up and return the vehicle. Thanks to its long range, the IONIQ 6 proved ideal for our test, allowing us to drive confidently without experiencing EV charging range anxiety.
For the first 14 days, we used the hardwired 48-amp ChargePoint Home Flex, followed by another 14 days with the 40-amp plug-in version.
The table below outlines each day’s charging durations for each setup and the miles we covered:
| Day | Miles Traveled | ChargePoint Home Flex 48A (Hours Charging) | ChargePoint Home Flex 40A (Hours Charging) |
|---|---|---|---|
| 1 | 50 | 2.0 | 2.0 |
| 2 | 150 | 2.5 | 4.0 |
| 3 | 200 | 4.5 | 5.0 |
| 4 | 150 | 4.0 | 4.0 |
| 5 | 250 | 5.0 | 6.5 |
| 6 | 200 | 4.5 | 4.5 |
| 7 | 200 | 4.5 | 5.5 |
| 8 | 200 | 5.0 | 5 |

| 10 | 150 | 3.0 | 5 |
| 11 | 200 | 4.0 | 4 |
| 12 | 150 | 4.0 | 4 |
| 13 | 200 | 4.5 | 5 |
| 14 | 50 | returned without charging | returned without charging |
ChargePoint Home Flex (Hardwired) Performance
For the first 14 days, we paired the IONIQ 6’s 77.4 kWh battery with the hardwired ChargePoint Home Flex 48A, utilizing an 11 kW onboard charger on a NEMA 14-50 circuit. Following the 80/20 charging rule (keeping the EV battery between 20% and 80% SoC), the 48A unit provided fast, consistent power, making overnight charging seamless.
The chart below visualizes the 14-day charging and discharging patterns, providing key insights into the IONIQ 6’s State of Charge (SoC) performance and charging behavior.
As shown in the 14-day charging and discharging patterns chart above, although the IONIQ 6 has built-in battery preconditioning features, we also used a traditional method by charging the EV immediately after driving. This helped precondition the battery, reducing charge time and improving charging rate and efficiency.
Charging patterns showed predictable SoC reductions of approximately 45.1% for 150-mile trips and 60.1% for 200-mile trips. Our hardwired circuit recorded 95% EV charging efficiency with charging times ranging from 2.5 to 5.0 hours, with longer sessions for deeper discharges.
The energy delivered vs. charging time chart below, based on our test results, demonstrates a stable energy transfer rate with minimal throttling and we never experienced EV charging voltage drops.
The hardwired 48A ChargePoint Home Flex proved to be an efficient and reliable home charging solution, minimizing downtime for daily long-range commutes.
ChargePoint Home Flex (Plug-in) Performance
For the next 14 days, we switched to the plug-in ChargePoint Home Flex 40A (9.6 kW). This test assessed its charging speed, energy efficiency, and practicality compared to the 48A hardwired version.
Following the same 80/20 EV charging strategy, SoC reductions ranged from 15.0% (50 miles) to 75.1% (250 miles) per day.
Our plug-in circuit achieved 94% EV charging efficiency, with charging times ranging from 2.0 to 6.5 hours. It replenished between 18.2 kWh and 59.3 kWh daily without overheating any component of the circuit, including the cables, outlet, or charger.
Compared to the 48A model, the 40A plug-in version required longer charge times:
- Over the 14 days, the total additional charging time was approximately 7.0 hours.
- Each session took 30-40% longer than the 48A version.
- The most significant single-day difference was +2.0 hours, while typical differences ranged from 0.5 to 1.5 hours per charge.
While the 40A plug-in version remained effective for home charging, users requiring faster turnaround for high-mileage daily driving may benefit from the hardwired 48A unit.
