Mercedes EQC 4Matic 2019-2020 charging cable

The Mercedes-Benz EQC 400 4MATIC arrived in 2019 as the brand's first all-electric SUV, pairing an 80 kWh usable battery with dual-motor all-wheel drive and a WLTP range of up to 269 miles. Unlike most electric cars, the 2019 EQC charges through a two-phase onboard charger rated at 7.4 kW, drawing 16A across two of the three lines in a standard European three-phase supply. Connected to a three-phase source, the EQC gains roughly 22 miles of range per hour and completes a full charge in around twelve hours. The CCS charging port sits on the right rear flank, in the same position as the fuel filler on a conventional GLC.

Why the two-phase charger decides everything

The EQC's onboard charger is wired to draw 16A per phase across two phases: 2 × 16A × 230V = 7.4 kW. It never draws more than 16A on any single line, regardless of what the cable or wallbox can supply. That makes the cable choice straightforward. A Voldt® Type 2 charging cable rated at 11 kW carries 16A per phase on three lines, which is exactly what the car asks for on two of them: full speed, no bottleneck, no wasted capacity. A 22 kW cable, rated at 32A per phase, works identically at 7.4 kW because the car never requests more than 16A. There is no speed advantage for this vehicle, but a 22 kW cable is worth considering if you plan to use it with a future car that can draw more.

What matters more than the cable is the supply behind the wallbox. On a three-phase home installation the car uses two phases at 16A each and charges at its full 7.4 kW: a complete charge in around twelve hours, comfortably within an overnight window. On a single-phase supply, which is what most UK homes provide, only one of the two phases is available. The car draws 16A on that one line for 3.7 kW, roughly half the speed, and no cable choice changes that. The charger itself is the limit: it is built for 16A per phase, not 32A, so a higher-rated cable cannot unlock more power from a single phase. For owners with single-phase power at home, the full 7.4 kW is available at any public or workplace charger that provides three-phase power, and the same 11 kW cable delivers it.

The charging port on the right rear flank mirrors a fuel filler position: reversing into a bay places the port closest to the charge point. A 6-metre cable handles most home driveways. Eight metres is the reliable everyday length for home and public charging alike. A 10-metre cable adds useful reach where the post sits further from the bay, and 15 metres covers longer driveways, hotel car parks, and less predictable public layouts without restriction.

Portable charging wherever a socket reaches

A Voldt® portable charger with a red three-phase commando plug connects to 16A three-phase CEE sockets and delivers the EQC's full 7.4 kW, because the car draws 16A on two of the three available phases. Red CEE sockets are found at workshops, industrial units, farm buildings, and marinas: anywhere a three-phase supply runs to an accessible outlet, this charger matches the speed of a dedicated home wallbox. A full charge takes around twelve hours. The current is adjustable between 8A and 16A, so you can dial it down to suit the supply or the situation.

The Voldt® blue CEE portable charger connects to the 16A single-phase sockets fitted at campsites and caravan parks across the UK and the continent, charging at 3.7 kW. Over a multi-night stay the charger steadily rebuilds range and keeps daily driving comfortable without a detour to a public rapid charger. The Voldt® three-pin portable charger plugs into any standard UK domestic socket at up to 2.8 kW, within the limits of what the household wiring can sustain. Connected overnight at a relative's house or a holiday let, it restores a meaningful share of the next day's driving range. A built-in thermal sensor tracks the plug temperature throughout the charge and reduces the current automatically if the connection warms up, protecting both the vehicle and the wiring.
