Mercedes GLC 300 e Charging cable

The Mercedes-Benz GLC 300e 4MATIC is a plug-in hybrid compact luxury SUV pairing a 2.0-litre turbocharged petrol engine with a 100 kW electric motor for 313 PS and 550 Nm of combined system output. The 23.4 kWh usable lithium-ion battery delivers a WLTP electric range of up to 130 km (81 miles), one of the longest in its class, so the average daily commute fits comfortably inside a single charge with the petrol engine held in reserve. AC charging runs through an 11 kW three-phase onboard charger via a Type 2 socket in the left rear quarter panel.

The right Type 2 cable for the GLC 300e in the UK

UK home charging is predominantly single-phase, and the most common home wallbox installation delivers 7.4 kW at 32A. The GLC 300e's onboard charger accepts whatever supply it receives, which means the cable is what decides the real charging speed. On a single-phase 32A wallbox, a 22 kW-rated Type 2 cable delivers the full 7.4 kW to the vehicle. An 11 kW-rated cable, wired for a maximum of 16A, restricts the flow to 3.7 kW. On the GLC 300e's 23.4 kWh battery that translates to a full charge in roughly 3 hours 20 minutes at 7.4 kW compared with around 6 hours 20 minutes at 3.7 kW. Both are viable overnight, but at 7.4 kW the car is ready long before bedtime, which matters for drivers who plug in after the school run and want a full battery for the evening.

At three-phase public infrastructure, either 11 kW or 22 kW, the GLC 300e settles at its 11 kW ceiling and completes a full charge in approximately 2 hours 30 minutes. On any three-phase supply, both cable ratings arrive at the same result, so the 22 kW cable makes sense as the universal choice: full speed on single-phase at home, full ceiling on three-phase in public, and ready for any future vehicle with a higher onboard AC rating without a hardware change. Voldt® supplies Type 2 cables in 6, 8, 10 and 15 metre lengths. The port sits on the left rear quarter, so reversing towards a wallbox is the natural approach at home, and 6 metres covers most driveways and garages. Eight metres suits public bays where the post isn't always aligned with the rear corner, and 10 or 15 metres covers hotels, car parks, and workplaces where the vehicle can't always park directly beside the charge point. The full Voldt® Type 2 cable range covers every combination of length and rating.

Portable charging for the GLC 300e

For weekends away, second addresses, and any location outside the fixed charging network, a portable charger keeps the electric side of the GLC 300e usable wherever there's a working socket. The Voldt® 11 kW three-phase red CEE portable charger plugs into an industrial red CEE three-phase socket, common at workshops, farms, holiday cottages with agricultural supplies, and any commercial premises. It matches the GLC 300e's full 11 kW onboard ceiling and completes a full charge from empty in approximately 2 hours 30 minutes, functioning as a mobile wallbox at any address with red CEE infrastructure.

The Voldt® 3.7 kW blue CEE portable charger uses the 16A single-phase blue commando socket found at caravan sites, marinas and outdoor commercial premises, and completes a full charge from empty in approximately 6 hours 20 minutes: a comfortable overnight refill during any stopover, without touching the public charging network. The Voldt® three-pin domestic charger plugs into a standard UK 13A socket and delivers up to 2.8 kW, within the limits of what the household wiring can sustain, giving a full charge from empty in approximately 8 hours 30 minutes. A built-in thermal sensor monitors the connection temperature during charging and automatically reduces the current if the plug or socket warms beyond a safe level, which makes it a sensible option when the driver is a guest at a family address or parking overnight at a location without any dedicated charging equipment.

Built to the standard the car sets

Every Voldt® cable and portable charger is CE, UKCA and TÜV certified, with an IP67 rating that keeps the connection sealed against rain, dust, and the general grit of British driveways year-round. Contacts are silver-plated copper for reliable current transfer and minimal heat build-up over long charging cycles, and every connector is tested for 10,000 mating cycles: comfortably beyond a decade of daily home charging. All Voldt® cables and portable chargers ship with a 3-year warranty and English-language technical support.
