What EV Charger Do You Need for a 2026 Mercedes-Benz EQS 580?
You need a 48 amp home charging setup to feed this car at its absolute maximum AC speed. The onboard charger limits the power intake to 11.5 kW. Buying a larger charging unit will not speed up the replenishment time. Match the equipment to the vehicle limit.
The numbers
| Maximum AC charging rate | 11.5 kW (48 A) |
|---|---|
| Charger size to buy | 48 A |
| Circuit breaker required | 60 A |
| Outlet / connection | hardwired (a 48 A EVSE must be hardwired -- no household receptacle is rated for it) |
| Charge port | J1772 |
| Full charge on Level 2 | about 11.5 hours |
| Range added per hour (Level 2) | about 32 miles |
| Full charge on a 120 V outlet | about 92 hours |
| Range added per hour (120 V) | about 4.0 miles |
| EPA rated range | 371 miles |
| Energy for a full charge | about 132.2 kWh at the wall |
Why 48 amps and not more
The battery holds 132.2 kWh of energy. Pulling 48 amps at Level 2 delivers 32 miles of range per hour. A full recharge takes 11.5 hours from empty. Feeding the car anything higher than 48 amps is a waste of money because the onboard hardware drops excess current. Stick to the specified amperage to fill the pack overnight.
What the install involves
Run a 60 amp breaker to support the 48 amp continuous draw safely. Hardwire the unit directly to the electrical supply because no household receptacle handles 48 amps without melting. Hire an electrician for the panel work and wiring run. Inspect your main service panel capacity before buying hardware.

Common questions
- Can I use a standard wall outlet?
- Level 1 charging on a standard household outlet gives you 4.0 miles of range per hour. A full tank takes 92 hours this way. You need a Level 2 circuit for daily driving.
- What connector does the car use?
- This model features a J1772 connector. Many vehicles this year ship with a NACS port and include an adapter. Confirm your physical port before ordering.
- Which charger should I buy?
- Look for a 48 amp unit with a J1772 plug like the Emporia Level 2 EV Charger or the Wallbox Pulsar Plus. Hardwire the connection to get the full 48 amps.
- Do I need a permit for the installation?
- Most local building codes require a permit for new high amperage circuits. Check with your municipal office before the electrician starts work.
Other vehicles
Charging times derived from EPA data for the 2026 Mercedes-Benz EQS 580. Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
