What EV Charger Do You Need for a 2025 Mercedes-Benz EQS 580?
Many owners buy an 80-amp home charger, but your car cannot use the extra capacity and wastes the money. You need a 48-amp Level 2 setup to match the vehicle onboard charger. Plug in at night and the 133.6 kWh battery fills completely in 11.6 hours. The car yields 371 miles of total range.

| Charge port | J1772 |
| Full charge on Level 2 | about 11.6 hours |
| Range added per hour (Level 2) | about 32 miles |
| Full charge on a 120 V outlet | about 93 hours |
| Range added per hour (120 V) | about 4.0 miles |
| EPA rated range | 371 miles |
| Energy for a full charge | about 133.6 kWh at the wall |
Why 48 amps and not more
Your car accepts a maximum of 11.5 kW through its onboard charger. Pushing more amperage from a larger supply unit does nothing because the car limits the intake. Buying a bigger charger only costs more money without speeding up your daily turnaround. The recommended 48-amp unit delivers 32 miles of range per hour of charging. This rate easily replenishes the battery during standard off-peak hours.
What the install involves
A 48-amp continuous load requires a 60-amp circuit breaker paired with heavy gauge wiring. Hardwiring is mandatory because no standard household receptacle handles 48 amps safely. Hire a licensed electrician to run the circuit from your main panel to the parking spot. They will mount the unit securely and verify that your electrical service can support the load.

- What connector does the car use?
- The vehicle uses a J1772 connector. Many 2025 models feature a NACS port alongside a J1772 adapter, so check your specific delivery before ordering hardware.
- Do I need a permit for the electrical work?
- Most municipalities require a permit for new high-amperage circuits. Your electrician should pull the permit and schedule the required municipal inspection.
- What is the efficiency of this vehicle?
- The car consumes 36.0 kWh per 100 miles. It earns an EPA rating of 93 MPGe.
