What EV Charger Do You Need for a 2024 Mercedes-Benz EQB 350?
Residential charging stations can push massive amounts of power, but your car dictates how much of that current reaches the battery. The 2024 Mercedes-Benz EQB 350 maxes out at 40 amps for home Level 2 charging. You need a 40 amp supply to hit the maximum onboard charging rate. Anything larger on the wall gets wasted.
The numbers
| Maximum AC charging rate | 9.6 kW (40 A) |
|---|---|
| Charger size to buy | 40 A |
| Circuit breaker required | 50 A |
| Outlet / connection | NEMA 14-50 outlet |
| Charge port | J1772 |
| Full charge on Level 2 | about 8.4 hours |
| Range added per hour (Level 2) | about 25 miles |
| Full charge on a 120 V outlet | about 56 hours |
| Range added per hour (120 V) | about 3.7 miles |
| EPA rated range | 207 miles |
| Energy for a full charge | about 80.3 kWh at the wall |
Why 40 amps and not more
Your car accepts a maximum of 9.6 kW on alternating current. Buying a 48 amp or 50 amp supply gives you zero speed gains because the onboard charger limits intake. The vehicle fills its battery in 8.4 hours at this speed. You recover 25 miles of range every single hour. Level 1 charging takes 50 extra hours, so skip the standard wall outlet entirely.
What the install involves
Call a licensed electrician to pull a fresh circuit and land it on the breaker. The job requires a 50 amp breaker to feed a NEMA 14-50 outlet safely. Hardwiring is also an option if you prefer skipping the plug entirely. Ask the electrician to check your service panel for spare capacity before buying hardware.

Common questions
- What connector does this vehicle use?
- Every non-Tesla EV sold in North America through 2024 uses the J1772 connector for AC Level 2 charging. You plug the cable straight into the driver side port without an adapter.
- Can I use a standard wall outlet?
- Plugging into a regular 120 volt outlet delivers 3.7 miles of range per hour. A full recharge from empty takes 56 hours using that method. Install a 240 volt circuit instead.
- What equipment works with this car?
- You need a 40 amp Level 2 charger that matches the vehicle max rate. Units like the Grizzl-E Classic 40A or the Home Flex NEMA 14-50 plug directly into a compatible outlet.
- Why does the EPA charge time differ slightly?
- The EPA rated charge time sits at 8.2 hours while the full calculation shows 8.4 hours. Federal test procedures do not always run at the exact peak AC rate of the car.
