Both plug-in versions of the B Class take a Type 2 to Type 2 cable, and on both the 32A version is the one to buy. What separates them is how much they hold, and so how long they sit on the drive.
There are two of them and they are easy to confuse, because Mercedes used the B 250 e badge twice. The 2015 to 2017 car, sold as the B-Class Electric Drive and later relabelled B 250 e, is fully electric with 28 kWh of usable battery from a 31 kWh pack. The 2020 to 2022 B 250 e is a plug-in hybrid: 15.6 kWh installed, about 10.6 kWh of it usable, with a petrol engine alongside it. Same socket, very different charging job.
The electric car's onboard charger is the one figure we cannot pin down. It is widely reported as 9.6 kW, which Mercedes UK has never confirmed. What Mercedes did publish was 3 to 4 hours from a wallbox. In a British house the distinction is academic, because domestic supplies here are single phase and 7.4 kW is the practical ceiling whatever the car will accept. A 32A Type 2 cable delivers that 7.4 kW, which puts 28 kWh in over roughly four and a quarter hours.
The plug-in hybrid is quoted at 7.4 kW, so the same 32A cable is again correct. With only 10.6 kWh to replace it finishes in about an hour and a half, which is short enough to be worth doing during a supermarket shop.
The 16A cable at 3.7 kW fits both cars but roughly doubles every figure above. It is worth buying only if the charge point you use is itself limited to 16A. The 3 pin cable is a fallback on the electric car, where 28 kWh at 2.3 kW runs to nearly fourteen hours, though it is more reasonable on the hybrid.
We also list a three phase 22 kW cable. It fits, and it will not charge either B Class faster, because neither car is quoted above 9.6 kW and a home supply is not three phase to begin with.
The petrol and diesel B Class models, the B 180, B 200, B 200 d and B 220 d, have no charging port and need nothing from this page.
| Cable Type | Max Charge Rate | Empty to Full | Verdict |
|---|---|---|---|
| Type 2 to 3 Pin: 5m or 10m | 2.3 kW | 13h45m | Emergency use only on a pack this size |
| Type 2 to Type 2, 16A: 5m or 10m | 3.7 kW | 8h30m | Only if your charge point is capped at 16A |
| Type 2 to Type 2, 32A: 5m or 10m | 7.4 kW at home | 4h15m. Mercedes quoted 3 to 4 hours from a wallbox | Best fit |
| Type 2 to Type 2, 32A three phase: 5m or 10m | 22 kW cable, far above anything the car is quoted at | No quicker than the 32A | No benefit on this car |
| Cable Type | Max Charge Rate | Empty to Full | Verdict |
|---|---|---|---|
| Type 2 to 3 Pin: 5m or 10m | 2.3 kW | 5h15m | Workable overnight on this smaller battery |
| Type 2 to Type 2, 16A: 5m or 10m | 3.7 kW | 3h15m | Adequate, but slower than the car allows |
| Type 2 to Type 2, 32A: 5m or 10m | 7.4 kW | 1h30m | Best fit. Uses the car's full 7.4 kW |

Compatible with all Type 2 cars
A Type 2 to Type 2 cable, in the 32A version. That applies to the 2015 to 2017 Electric Drive with its 28 kWh usable battery and to the 2020 to 2022 B 250 e hybrid at 7.4 kW. Neither car has ever used a Type 1 socket, so one cable covers both.
Look for a petrol filler. The 2015 to 2017 Electric Drive has no engine and holds 28 kWh usable. The 2020 to 2022 B 250 e is a plug-in hybrid with a 15.6 kWh pack, roughly 10.6 kWh of it usable, and a fuel cap as well as a charge flap. Both use the same cable.
No, not for either B Class. The electric car is reported at 9.6 kW and the hybrid at 7.4 kW, and a UK home is single phase, which caps you at 7.4 kW anyway. The 32A single phase cable reaches that ceiling for less money. For 22kW posts and workplaces.
Around an hour and a half from empty on a 32A cable at 7.4 kW, since there is only about 10.6 kWh to put back. The 16A cable stretches that to roughly three and a quarter hours, and a 3 pin lead at 2.3 kW takes a little over five hours, which still fits inside a night.
No. The B 180, B 200, B 200 d and B 220 d are petrol and diesel models with no charging port anywhere on the car, so nothing on this page will connect to them. Only the Electric Drive and the B 250 e plug in. Check for a charge flap before ordering.
Take 5m if the B Class parks within a couple of metres of the charge point and faces the right way. Take 10m if the socket is behind you, across a shared bay, or on the far side of a garage. Longer 15m and 20m 32A cables are stocked for difficult driveways.

Two very different B-Class models plug in, and they are easy to confuse. The B-Class Electric Drive of 2015 was fully electric. The B 250 e of 2020 is a plug-in hybrid with a petrol engine. Both use Type 2, so the same cable fits either, but they are not the same car.
Neither has ever used a Type 1 socket. Trim and line make no difference to charging.

Cable Type:
How do I Choose?The cable connection depends on what connection type your car accepts. If you don't know, use our handy car reg checker.
Cable Length:
Sizing guideWe offer different length cables to suit your needs, whether you park next to your charger at home or at the office.
Rated Power (Charge Speed):
How do I Choose?Rated power is the fastest the cable can charge. Match it to your car and your charge point. A higher rated cable still works at every lower speed.
Accessory Add-Ons
We offer a range of products to help store and transport your charging cable. Choose from the accessories below:
A charging cable that connects electric vehicles (EVs) with a Type 2 connector to charging points is also equipped with a Type 2 socket. It supports faster charging speeds and is commonly used across Europe for EVs with this standard connection.
This cable allows electric vehicles with a Type 2 socket to charge from a standard UK 3-pin domestic outlet. It provides a slower charge but is useful for home or emergency charging when dedicated charging stations aren't available.
A cable used to extend the reach of a Type 2 charging cable. It's helpful when the existing cable is too short to connect an electric vehicle to the charging point, providing more flexibility in parking.
A fixed charging cable attached to a charging point, designed for electric vehicles with a Type 2 socket. The tethered design eliminates the need to carry a separate cable, offering convenience for regular charging at home or work.
A charging cable that connects electric vehicles with a Type 1 socket to charging points equipped with a Type 2 outlet. This allows EVs with the older Type 1 standard to use more modern charging infrastructure.
This cable enables electric vehicles with a Type 1 connector to charge from a standard UK 3-pin household outlet. It's suitable for slower charging at home when dedicated EV charging points aren't accessible.
A 5M charging cable is the shortest length that we offer. It is a great option if you can park close to the charge point and do not need much length to reach your car.
A 10M charging cable is the most popular length. It allows you to have enough flexibility whilst still being easy enough to move. This is a great option if you cannot park close to the electricity supply.
A 15M charging cable is a great choice if you need some extra flexibility, i.e. get past another car or reach the other end of a driveway. The length of the cable does not affect the charging speed.
A 20M charging cable is the longest cable that we currently offer. 20M reaches the vast majority of locations where you would want to charge your car. Always use one continuous cable. Never join two charging cables together and never charge through an extension lead, because the join is where heat builds up.
The choice if you will charge from a standard UK 3 pin socket. It runs at the most the socket can safely supply, and the control box lets you turn the current down for a slower, gentler charge overnight or on an older circuit.
A 16amp cable will be able to charge at 3.7kW. This is the cheapest product if your car's max charge speed is 3.7kW. If you have two electric cars or are looking to purchase another it might be worth considering a faster charging cable as this could limit charge speeds moving forward.
A 32amp charging cable will be able to charge at 7.4kW, which is the most a single phase UK home supply can deliver. A 32amp cable also charges at every lower speed (for example 16amp, 3.7kW), so it is the right choice if your home charge point is 7.4kW or you mostly charge at home.
A 32amp 3-phase charging cable will be able to charge at all speeds up to 22kW, so the cable never limits your charge speed at home or in public. It is also capable of charging at all lower charge speeds.
