Mercedes S 550 e EV charger: which one fits best?
The Mercedes S 550 e is a plug-in hybrid. At home it charges at up to 3.7 kW on a single phase. That ceiling sits in the car's onboard charger, not in the wall charger, so a heavier model adds no speed. Mercedes puts a full charge at around two hours. Want to compare more widely?

Which EV charger fits the Mercedes S 550 e?
The S 550 e never charges faster than 3.7 kW. A more powerful charger buys you no speed. Many drivers still pick an 11 kW three-phase model. Such a charger splits its power over three phases, 16 A each. This car uses just one of those phases, so it still reaches its full 3.7 kW. You lose nothing today and the charger is ready for a fully electric car later.
Look closely at the MID meter. That is a calibrated kWh meter, which records exactly how much electricity a charging session used. It measures your charging separately from the rest of your household use. So you always know what charging at home costs. In our range that calibrated meter starts at 11 kW, so an EV charger with a MID meter is a second reason to choose a three-phase model.
Browse all 11 kW EV chargers in our range. Do you only have a single-phase connection at home? Then a 7.4 kW EV charger is more than enough for this car. In our range no charger at that power has a built-in calibrated meter. Our home EV chargers category gathers every model that suits a driveway or a garage.
How long does the Mercedes S 550 e take to charge?
Mercedes puts the charging time at a wallbox at around two hours. The 8.7 kWh is the total pack, and the part you actually charge is smaller. That is why two hours is enough at 3.7 kW. A heavier charger does not change it, because the car caps itself at 3.7 kW. Plug the S 550 e in during the evening and it is full again well before your next trip. We always recommend having the connection made by a qualified electrician, because that is safer. Check what your own insurer requires.

Frequently asked questions
Does the Mercedes S 550 e need a three-phase connection?
No. The S 550 e charges at up to 3.7 kW on one phase, so an ordinary single-phase connection is enough. A three-phase 11 kW charger works too, but it does not make the car any faster. It is mainly worth choosing if you are preparing for a fully electric car.
Do I need an EV charger with a MID meter?
You do not need one to charge, but it is useful. A MID meter is a calibrated kWh meter. It shows exactly what a charging session cost you, separately from your household use. In our range that meter starts at 11 kW. You get it on a three-phase model, not on a single-phase one.
Which plug does the Mercedes S 550 e have?
The S 550 e has a Type 2 connection, the European standard. Almost every modern EV charger works with it directly, so you do not need an adapter to charge at home.
