What EV Charger Do You Need for a 2025 Mercedes-Benz EQE 350?
A full charge takes 11.6 hours on a Level 2 setup. That timeline lets you plug in before bed and wake up with a full battery. Your car accepts up to 40 amps.
The numbers
| Maximum AC charging rate | 9.6 kW (40 A) |
|---|---|

| Full charge on Level 2 | about 11.6 hours |
| Range added per hour (Level 2) | about 27 miles |
| Full charge on a 120 V outlet | about 77 hours |
| Range added per hour (120 V) | about 4.0 miles |
| EPA rated range | 308 miles |

Why 40 amps and not more
The onboard charger maxes out at 40 amps. Buying a 48 amp or 50 amp unit wastes money because the car cannot draw the extra power. It will cap the draw at 40 amps. A 40 amp EVSE adds 27 miles of range every hour. That easily covers daily driving needs.
What the install involves
You need a 50 amp breaker paired with heavy gauge wiring. The circuit feeds a NEMA 14-50 outlet. Hardwiring is also an option if you prefer a permanent connection without a plug. Call an electrician to inspect your panel before buying hardware. High amperage circuits require professional installation to prevent thermal overload.

Common questions
- Can I use a standard wall outlet?
- Yes, but Level 1 charging takes 77 hours for a full charge. It only adds 4.0 miles of range per hour. You need Level 2 for normal daily use.
- What plug type does the car use?
- The car uses a J1772 connector. Many 2025+ vehicles ship with a NACS port but include a J1772 adapter, so a J1772 home charger still works. Confirm your car's port before buying.
- Do I need a 40 amp charger?
- Yes, because your car has a 40 amp maximum onboard limit. Anything smaller slows down your charge time unnecessarily.
- What is the efficiency of this vehicle?
- The vehicle consumes 36.0 kWh per 100 miles. That translates to an EPA rating of 94 MPGE.
Other vehicles
Charging times derived from EPA data for the 2025 Mercedes-Benz EQE 350 (covering 4 EPA trim listings). Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
