What EV Charger Do You Need for a 2026 Mercedes-Benz EQS 680 Maybach?
Forty amps is the target. Your 2026 Mercedes-Benz EQS 680 Maybach maxes out its onboard charger at 9.6 kW. A 40-amp Level 2 setup fills the 119.5 kWh battery from empty in 12.4 hours. Plug it in overnight and walk away.

| EPA rated range | 300 miles |
| Energy for a full charge | about 119.5 kWh at the wall |
Why 40 amps and not more
Your car accepts a maximum of 40 amps for home charging. Buying a 48-amp or 50-amp supply wastes money because the onboard hardware caps the intake. Extra capacity at the wall does nothing for charge speed. Stick to the 40-amp limit to match your vehicle specs. The EPA test pegs the full charge at 14.0 hours due to testing methodology differences.
What the install involves
You need a 50-amp circuit breaker to run this equipment safely. The circuit feeds a NEMA 14-50 outlet located near your parking spot. Hardwiring remains an option if you prefer to skip the plug entirely. Call an electrician to inspect your panel before buying parts. Code requires proper wire gauge and a dedicated breaker for continuous loads.
