What EV Charger Do You Need for a 2025 Mercedes-Benz AMG EQE?
Standard household panels can push far more current than your car can handle. Your car tops out at 40 amps on Level 2 charging. Buy a 40 amp unit to match the onboard charger.
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 10.9 hours |
| Range added per hour (Level 2) | about 21 miles |
| Full charge on a 120 V outlet | about 73 hours |
| Range added per hour (120 V) | about 3.2 miles |
| EPA rated range | 230 miles |
| Energy for a full charge | about 104.7 kWh at the wall |
Why 40 amps and not more
Your car accepts a maximum of 9.6 kW through its onboard charger. Buying a larger 48 amp or 80 amp supply wastes money because the car cannot draw the extra power. Extra capacity sits idle in the hardware. The 104.7 kWh battery refills from empty in 10.9 hours at this maximum rate. Every hour plugged in adds 21 miles of range.
What the install involves
You need a 50 amp breaker to feed the equipment safely. The circuit connects to a NEMA 14-50 outlet. Hire an electrician if your panel lacks the capacity or if you need new wiring run through the garage. Hardwiring is also an option for permanent setups, though a plug-in unit works fine with the specified outlet.

Common questions
- Can I use a Level 1 charger?
- Level 1 charging is possible using standard household outlets. It takes 73 hours to refill the battery from empty and adds 3.2 miles of range per hour. This speed only suits very low daily driving needs.
- What plug does the car use?
- The car uses a J1772 connector. This model year falls in the industry transition. Many vehicles ship with a NACS port but include a J1772 adapter, so verify your physical port before ordering.
- How does the EPA charge time differ?
- The EPA rated charge time is 10.8 hours, which is slightly faster than the full charge calculation due to testing parameters. Both figures yield a rate of 21 miles per hour of charging. Real world results match these numbers closely.
- Which charger models fit this car?
- The Grizzl-E Classic 40A, the Grizzl-E Mini Portable, and the ChargePoint Home Flex NEMA 14-50 all supply the correct 40 amps. Each option connects via the required J1772 standard.
