What EV Charger Do You Need for a 2024 Mercedes-Benz EQS 680 Maybach?
You need a 40 amp Level 2 home charger to fill the battery of this luxury SUV overnight. The onboard charger caps your intake at 9.6 kW, meaning larger units will not speed up your daily turnaround. Level 1 charging takes 94 hours, so do not rely on a standard household outlet for this 134.8 kWh pack.

Why 40 amps and not more
Your car accepts a maximum of 40 amps on alternating current. Buying a 48 amp or 80 amp supply wastes money because the vehicle limits the current draw. Feeding it 40 amps restores 23 miles of range every hour. A full recharge from empty takes 14.0 hours. Stick to the 40 amp ceiling.
What the install involves
You need a 50 amp breaker feeding a NEMA 14-50 outlet to run the equipment properly. Hardwiring is also an option for permanent setups. Hire a licensed electrician to inspect your panel capacity before plugging anything in. Code requires heavy gauge copper wiring for continuous loads of this size.

Common questions
- Can I use a standard wall outlet?
- You can plug into a standard household outlet for Level 1 charging, but it adds only 3.4 miles of range per hour. A full recharge takes 94 hours this way. Install a Level 2 setup instead.
- What connector does this car use?
- Your vehicle uses a J1772 connector for all AC Level 2 charging sessions. Every non Tesla EV sold in North America through 2024 uses this standard.
- Do I need a hardwired charger or a plug in model?
- Both options work if matched to your 50 amp breaker and NEMA 14-50 outlet. Units like the Grizzl-E Classic or ChargePoint Home Flex plug straight in without hardwiring.
- How much range do I get per hour?
- You recover 23 miles of range for every hour connected to a 40 amp Level 2 supply. The EPA rating confirms this exact speed.
