Mercedes-Benz E300e
Charging cable
Charges about 50% faster on 22 kW public posts than a 7.4 kW cable.
Why this fits your E300e+−
The Mercedes-Benz E300e has a Type 2 inlet and a three-phase 11kW onboard charger. The 22kW cable carries its full 11kW on three-phase chargers. A 7.4kW cable would cap it. On a single-phase home wallbox both cables charge at the same 7.4kW.

Charging
the Mercedes-Benz E300e.
The Mercedes-Benz E300e is a plug-in hybrid executive saloon or estate, based on the W214 generation E-Class and on sale in the UK from 2023. It uses a 25.4kWh battery pack, a sizeable figure for a PHEV that translates to a meaningful electric-only range for everyday journeys. The E300e charges through a Type 2 inlet for AC and a CCS port for DC rapid charging up to 60kW, giving it more flexibility at public charge points than older PHEV alternatives.
To charge at home or at a public AC point, you bring your own Type 2 to Type 2 cable. The E300e's onboard AC charger accepts up to 11kW on a three-phase supply. Whether you actually benefit from that 11kW capability depends on the supply at your home or workplace, as most UK domestic connections are single-phase.
The E300e's 60kW DC capability is among the highest offered on a PHEV, making it genuinely practical for adding range at motorway service area rapid chargers. Rapid (DC) times are for a 10 to 80% charge, the way manufacturers quote them. Real-world charging varies with temperature, battery state and the charger itself.
7.4 kW or 22 kW?
Which cable does
the E300e need?
The E300e's onboard AC charger tops out at 11kW across three phases. Nearly all UK homes are fed by a single-phase supply, which limits home AC charging to 7.4kW no matter what wallbox or cable rating you choose. A 7.4kW Type 2 cable covers every scenario a single-phase home can offer and is the cost-effective default for most E300e drivers.
Moving up to a 22kW rated cable is worthwhile if your property has a three-phase supply or if you regularly park at 22kW public AC charge points. In those cases the E300e draws its full 11kW. On a single-phase home circuit the 22kW cable charges at the same 7.4kW as the cheaper option, so the upgrade is about access to faster public or commercial charging rather than any speed gain at home.
What does it cost to charge?
Filling the 25.4kWh battery from flat costs roughly £1.90 on an off-peak EV tariff at around 7.5p per kWh, or around £6.85 at a standard domestic rate of around 27p per kWh. Setting up an overnight EV tariff and a dedicated home wallbox is the most cost-effective approach for regular E300e ownership. Public DC rapid charging, typically 45p to 80p per kWh at public sites, is best reserved for convenience on longer runs. Always check current tariff rates as prices change.

Mercedes-Benz E300e FAQs
Good
questions.
Still not sure? Our team will confirm the right cable for your vehicle.
Contact usWhat charging cable does the Mercedes-Benz E300e need?+−
The Mercedes-Benz E300e has a Type 2 inlet, so it needs a Type 2 to Type 2 cable for UK home and public charging. It charges on up to three-phase AC at up to 11kW.
Can the Mercedes-Benz E300e charge at 22kW?+−
Yes, the Mercedes-Benz E300e has a three-phase onboard charger, so with a 22kW cable and a three-phase supply it can charge at up to 11kW.
What length charging cable should I get?+−
5m suits most home and public charge points. Choose 7.5m or 10m if the charge point is far from your car's charging port or you park on the far side of a bay.
What charging cable does the Mercedes E300e need?+−
A Type 2 to Type 2 cable works at home wallboxes and public AC charge points. A 5m cable suits most setups. For single-phase home supplies, a 7.4kW cable gives the full available speed. A 22kW cable is only beneficial if you have a three-phase supply at home or use 22kW public AC points regularly.
Can the Mercedes E300e W214 charge at 11kW?+−
Yes, the W214 E300e's onboard charger supports 11kW on a three-phase supply. However, most UK homes are single-phase, meaning home AC charging is limited to 7.4kW regardless of wallbox rating. You need a three-phase supply or a 22kW public AC point to reach the car's 11kW maximum.
How long does the Mercedes E300e take to charge at home?+−
On a 7.4kW single-phase wallbox, the 25.4kWh battery takes roughly 3.5 to 4 hours from empty. On a three-phase 11kW supply that falls to around 2.5 hours. A 3-pin domestic socket is considerably slower, around 9 to 10 hours, and works best as an emergency backup rather than a daily charging routine.
Does the Mercedes E300e support rapid DC charging?+−
Yes. The W214 E300e accepts DC charging up to around 60kW via CCS, which is high for a PHEV. DC rapid charging uses the tethered cable at the public charge point itself, not a cable you purchase. Your Type 2 to Type 2 cable is for AC charging only.
