A Mercedes GLC 300e charging cable has more work in front of it than most plug-in hybrid cables. The current X254 car, on sale since 2023, holds 25.28 kWh usable from a 31.2 kWh gross pack and covers 77 miles on electricity alone, a bigger usable battery than several city cars sold as full EVs. It accepts 11 kW on AC as standard, and that combination is what makes the cable choice matter here.
Every Mercedes-Benz GLC 300e takes a Type 2 to Type 2 Charging Cable, X254 and the older X253 alike. Petrol, diesel and mild-hybrid GLCs have no socket at all. The separate GLC with EQ Technology is a fully electric car, a different vehicle, and not what this page is about.
The GLC 300 de, the diesel plug-in hybrid rated at 74 miles of electric range, uses the identical cable, so every recommendation below applies to it just as it does to the petrol 300e.
Eleven kilowatts is a three-phase measurement. A British house is fed by a single phase, which holds the GLC 300e to 7.4 kW at home, and a 32A single-phase Type 2 cable passes every watt of that through. From empty the X254 is full in 3 hours 45 mins and puts back about 23 miles for each hour it stays connected. On a 25.28 kWh pack those numbers are the difference between plugging in and actually running on electricity.
Drop to a 16A cable and the current GLC 300e is pegged at 3.7 kW. Empty to full goes from 3 hours 45 mins out to 7 hours 45 mins, and the hourly gain roughly halves to 11 miles. Most off-peak tariff windows run five or six hours: the 32A cable clears the entire battery inside one, the 16A cable finishes about a quarter short every night, and on a car this heavy that shortfall gets made up by the engine.
Where a genuine three-phase supply exists, usually a workplace or a commercial site, the X254 reaches its full 11 kW and completes in 2 hours 30 mins. At a normal house a three-phase cable simply has two phases with nowhere to connect. Mercedes-Benz UK does publish a DC rapid capability for the current car, but rapid units come with their own attached lead, so it has no bearing on which cable you buy.
The X253 GLC 300e ran 13.5 kWh and about 28 miles of electric range, close to a third of what the current car carries. Mercedes-Benz does not split that figure into gross and usable. It charges at 7.4 kW single phase, so the 32A cable is still the right buy and fills it from empty in 2 hours flat, but a three-phase cable adds nothing because the car cannot reach beyond 7.4 kW on any supply. A 16A cable doubles that to 4 hours, which is survivable on a battery this size in a way it is not on the newer one.
Both generations put the charge port at the rear, on its own flap separate from the fuel filler, so it is not something that changes between model years. What changes is how you park. Reverse the GLC onto a driveway with the wallbox near the house and 5m is plenty. Park nose in and the cable has to run the full 4.72m of the car before it reaches the flap, which is the point at which 10m stops being a luxury. 15m and 20m exist for shared parking and detached garages.
A Type 2 to 3-Pin cable feeds either GLC 300e at 2.3 kW. On the current car that is 7 miles an hour and 12 hours 30 mins from empty, so a household socket cannot realistically keep a 25.28 kWh pack topped up night after night. Its value is away from home, at family for a weekend or a holiday let with an outdoor socket and nothing else, where 12 hours parked up still returns a full battery. It is IP67 sealed for outdoor use.
Mercedes-Benz uses closely related plug-in hardware across the range, so the C 300 e and the E 300 e and E 300 de also charge at 11 kW, while the GLE 400 e and GLE 350 de sit a size above. Our full Mercedes charging cable range covers every plug-in model sold here.
Cables meet the IEC 62196 Type 2 standard, are CE certified, and work between -30C to +50C, or +60C for the 3-pin. IP55 sealing on the Type 2 to Type 2, IP67 on the Type 2 to 3-Pin. Two year manufacturer's warranty and free next working day UK delivery.
Maximum onboard AC charging speed: 7.4 kW, single phase
| Cable Type | Max Charge Rate | Empty to Full | Range Added Per Hour | Verdict |
|---|---|---|---|---|
| Type 2 - 1-Phase, 16A (5m / 10m) | 3.7 kW | 4 hours | approx. 8 miles | Half the speed for a small saving |
| Type 2 - 1-Phase, 32A (5m / 10m) | 7.4 kW | 2 hours | approx. 15 miles | Best Fit at home |
| Type 2 - 3-Phase, 32A (5m / 10m) | 7.4 kW (car limited) | 2 hours | approx. 15 miles | The car caps it, skip it |
| Type 2 to 3-Pin (5m / 10m) | 2.3 kW | 6 hours 30 mins | approx. 5 miles | Useful away from home |
Maximum onboard AC charging speed: 11 kW, three phase. A single-phase British supply brings that down to 7.4 kW.
| Cable Type | Max Charge Rate | Empty to Full | Range Added Per Hour | Verdict |
|---|---|---|---|---|
| Type 2 - 1-Phase, 16A (5m / 10m) | 3.7 kW | 7 hours 45 mins | approx. 11 miles | Too slow for this battery |
| Type 2 - 1-Phase, 32A (5m / 10m) | 7.4 kW | 3 hours 45 mins | approx. 23 miles | Best Fit at home |
| Type 2 - 3-Phase, 32A (5m / 10m) | 11 kW (three-phase supply only) | 2 hours 30 mins | approx. 34 miles | Worth it at a three-phase site |
| Type 2 to 3-Pin (5m / 10m) | 2.3 kW | 12 hours 30 mins | approx. 7 miles | Emergency and away days only |
The 2020 to 2022 times are based on the 13.5 kWh figure because Mercedes-Benz does not publish a usable capacity for that car, so they read slightly optimistic. The 2023 on times use the published 25.28 kWh usable capacity. The figure comes down in winter and at sustained high speed.
We pride ourselves on the quality of our cables. Every cable comes with a 2 year manufacturer's warranty, and the jacket will survive being driven over, though we would rather you did not make a habit of it.

Our cables are safe to use whatever the weather. Type 2 to Type 2 cables are IP55 rated, CE marked, and work from -30°C to +50°C. Type 2 to 3 pin cables are IP67 rated, CE marked and work from -30°C to +60°C.
Protection against temperature
Our cables fit any electric car or plug-in hybrid with a Type 2 inlet, including Audi, BMW, Volvo, Mini, Mercedes, Kia, Hyundai, Volkswagen, Smart and Toyota. Use our car reg checker to confirm your car.
Compatible with all Type 2 cars
A Mercedes GLC 300e needs a Type 2 to Type 2 charging cable, and on both generations the 32A single-phase version is the one to own. The 2023 on car is rated at 11 kW, which becomes 7.4 kW on a British domestic supply. The 2020 to 2022 car is rated at 7.4 kW outright. In both cases the 32A cable delivers the car's full home rate and a 16A cable does not.
Yes, the Mercedes GLC 300 de takes exactly the same Type 2 to Type 2 charging cable as the petrol GLC 300e. It is the diesel plug-in hybrid version, rated at 74 miles of electric range, and its inlet, its charging behaviour and its cable choice are identical. The 32A single-phase cable is the buy.
At home, yes. The 2023 on Mercedes GLC 300e is rated at 11 kW and the 2020 to 2022 car at 7.4 kW, but a single-phase British supply brings both down to 7.4 kW, so they draw the same power. What differs is duration: 3 hours 45 mins to refill the current car's 25.28 kWh against 2 hours for the older 13.5 kWh pack.
Only where three-phase power is actually available, which in practice means a workplace or an industrial unit. Given three phases the 2023 on Mercedes GLC 300e hits its full 11 kW and is done in 2 hours 30 mins rather than 3 hours 45 mins. Plugged in at a typical British house it achieves nothing the 32A single-phase cable was not achieving already, and the 2020 to 2022 GLC 300e cannot go beyond 7.4 kW on any supply whatsoever.
A 2023 on Mercedes GLC 300e takes 12 hours 30 mins from empty on a three-pin socket, gaining roughly 7 miles an hour at 2.3 kW. The 2020 to 2022 car, with its smaller 13.5 kWh battery, needs 6 hours 30 mins. Both will finish overnight, though the current one only just manages it, which is precisely why a wallbox and a 32A cable suit that car so much better.
Work out the distance from your socket to the rear of the GLC 300e as it normally parks, on the side the charge flap sits. The GLC is 4.72m long, so parking nose in towards a wallbox on the house wall means the cable travels the length of the car and 10m becomes the realistic choice. Reverse onto the drive and 5m generally reaches. 15m and 20m cover shared parking areas and detached garages.

Two generations of GLC 300e plug in, and the newer one carries close to twice the battery. The 2023 car holds 25.28 kWh usable and is rated at 11 kW, which a single-phase British home delivers as 7.4 kW. The 2020 to 2022 car holds 13.5 kWh and is rated at 7.4 kW outright. The diesel GLC 300 de takes the same cable. The fully electric GLC with EQ Technology is a separate model.

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.
