Mercedes-Benz E 300 de EV charger: which one fits best?
The Mercedes-Benz E 300 de is a diesel plug-in hybrid with a modest 13.5 kWh battery. It charges at home through a Type 2 connector at up to 7.4 kW, always on a single phase. That changes the choice of charger. You don't need a heavy 22 kW unit to fill this Mercedes quickly. Our overview of EV chargers for Mercedes covers the rest of the range.
For the E 300 de we recommend a charger from our 7.4 kW EV chargers.

Why single-phase charging decides everything on this Mercedes
The E 300 de can only charge on one phase. That has a consequence which surprises a lot of owners. An 11 kW charger is three-phase at 3x16 A, and it actually gives this car less. It receives just 3.7 kW, because it can use only one of the three phases.
A 7.4 kW charger on a single phase at 32 A delivers the full power the car is capable of. A 22 kW unit adds nothing at all here.
If heavy appliances share the same circuit at home, look for load balancing. The charger then measures how much power is still free and turns itself down automatically, so the circuit never overloads.
Which EV charger suits the Mercedes-Benz E 300 de?
Because this Mercedes charges on one phase, a 7.4 kW charger is the smartest and cheapest match. Look for one with a built-in MID-meter. That is a certified kWh meter, and it records exactly what the car has used, separately from the rest of your household.
In our view that record is no longer optional. It shows what the car actually costs to run, and it is the document an employer or leasing company accepts before reimbursing you. In the Netherlands there is a third reason: private drivers can claim back up to 500 euro a year through their energy supplier from 2026. That scheme is available in the Netherlands only, and it needs a certified meter.
Our EV chargers with a MID-meter hold every model that has one built in. If you want the simpler units without an app or a meter, look at our EV home chargers.
We arrange installation in the Netherlands, Flemish Belgium and Germany, carried out by our certified partner. We ship worldwide, but outside those three countries the installation is yours to organise. We always recommend having the connection made by a qualified electrician. It is safer, and many insurers expect it.
How long does the Mercedes-Benz E 300 de take to charge?
On a 7.4 kW charger the E 300 de is full again in about 2 hours. On an 11 kW unit the power drops to 3.7 kW, because the car accepts only one phase. That puts you at roughly 3.5 to 4 hours. Plug in during the evening and it is ready well before you leave.
A mobile charger through a wall socket works too, but keep that as a back-up rather than your daily solution.
The E 300 de uses a Type 2 connector, like most modern chargers. You only need a separate Type 2 charging cable for public charge points. The same goes for a charger with a socket instead of a fixed cable.

Frequently asked questions
Does the Mercedes-Benz E 300 de need a three-phase charger?
No. The E 300 de always charges on a single phase at up to 7.4 kW. A three-phase 11 kW charger gives this car only 3.7 kW. A 7.4 kW single-phase unit is the logical choice.
Do I need an EV charger with a MID-meter?
For almost every driver, yes. A certified kWh meter separates the car's consumption from the rest of the house, so you can see what charging really costs. It is also the proof an employer or leasing company needs before reimbursing you. In the Netherlands it is the condition for the yearly refund through your energy supplier from 2026.
