What home charger does the Mercedes-Benz EQB need?
| Model years | Trims | Charger | Breaker |
|---|---|---|---|
| 2022, 2024-2025 | all trims | 40 A | 50 A |
The Mercedes-Benz EQB accepts 9.6 kW on AC, which calls for a 40 A charger on a 50 A breaker. That is true of the 2022, 2024 and 2025 models alike.
Why 40 amps and not more
A 48 A charger won't help, because the EQB stops at 40 A, and it costs more to install since it needs a bigger circuit and hardwiring. A 40 A unit is the easiest size to fit, since it can plug into a NEMA 14-50 outlet. Dropping to a 32 A charger brings a 2025 from 25 to 31 miles of range per hour down to 20 to 25.
Charging time by model year
| Year | EPA range | Level 2, miles per hour | Level 2, empty to full | 120 V, miles per hour |
|---|---|---|---|---|
| 2025 | 205 to 251 mi | 25 to 31 | 8.2 to 8.4 h | 3.7 to 4.6 |
| 2024 | 205 to 251 mi | 25 to 31 | 8.2 to 8.4 h | 3.7 to 4.6 |
| 2022 | 227 to 243 mi | 27 to 29 | 8.3 to 8.4 h | 4.1 to 4.3 |
Level 2 figures assume a charger that supplies the car's full rate. Where a year shows a range, it spans that year's trims.
The EQB charged the same way throughout. A 2022 adds 27 to 29 miles of range per hour and fills in 8.3 to 8.4 hours, and the 2024 and 2025 cars are close behind at 8.2 to 8.4 hours. Range sits between 205 and 251 miles.
What the install involves
A 40 A charger plugs into a NEMA 14-50 outlet on a 50 A breaker, or it can be hardwired. The plug-in route is handy if you move house. Hardwiring suits a charger that stays put, and avoids wear on the receptacle from nightly use.
- 40 A charger: 50 A breaker, NEMA 14-50 outlet.
- Charge port, 2022: J1772. Every non-Tesla EV sold in North America through 2024 uses the J1772 connector for AC Level 2 charging.
- Charge port, 2024: J1772. Every non-Tesla EV sold in North America through 2024 uses the J1772 connector for AC Level 2 charging.
- Charge port, 2025: J1772. From 2025 the industry is moving to the NACS port, and makers switch at different times. Some of these cars have a J1772 port and some have NACS with an adapter, so look at the port on your own car before choosing a charger's plug.
