Mercedes EQB charging cable

The Mercedes EQB combines compact SUV practicality with optional seven-seat capacity, built on the GLB platform. The EQB 250 uses a 66.5 kWh usable battery paired with an 11 kW three-phase onboard charger, with a WLTP range of up to 442 km (275 miles). The EQB 250+ increases usable capacity to around 70.5 kWh and extends WLTP range to up to 547 km (340 miles), without changing the AC charging specification. The dual-motor EQB 300 4MATIC and EQB 350 4MATIC share the same 66.5 kWh pack and the same 11 kW AC ceiling, with all-wheel drive and higher combined outputs. Connected to a three-phase wallbox or public charge point, the EQB gains approximately 50 km of range per hour. The CCS Type 2 inlet sits on the right rear flank, where the fuel filler would be on a conventional GLB.

The best charging cable for the Mercedes EQB

A Voldt® Type 2 charging cable at 11 kW is the correct match for every EQB variant, delivering the car's full AC charging rate at any compatible three-phase wallbox. A 22 kW cable works equally well at 11 kW and is worth considering if you plan to use it with a higher-capacity vehicle in the future.

On a single-phase home wallbox (7.4 kW), an 11 kW three-phase cable bottlenecks the session to 3.7 kW, as its conductors are rated at 16A per phase rather than the 32A a single-phase wallbox delivers on one line. At 3.7 kW, the 66.5 kWh battery takes around 20 hours for a full charge. A 22 kW cable, whose conductors are rated at 32A per phase, carries the full single-phase load and delivers 7.4 kW, reducing that to approximately ten hours. For owners with a single-phase home installation, a 22 kW cable is the practical choice.

The right-rear port mirrors the position of a conventional fuel filler, so reversing into a bay puts the port closest to the post. For most home driveways a 6-metre cable is comfortable. An 8-metre cable is the practical everyday standard for drivers charging at both home and public locations. A 10-metre cable offers additional flexibility at public charge points where parking orientation is less predictable. A 15-metre cable handles hotel car parks, wider parking spaces, and longer driveways without restriction.

Flexible charging while travelling

The Voldt® portable CEE charging cable connects to industrial CEE sockets and is available up to 22 kW via three-phase CEE. For the EQB, output is capped at the car's 11 kW onboard charger ceiling regardless of socket rating. On a 16A three-phase CEE socket (11 kW), the 66.5 kWh battery charges fully in around six and a half hours; the 250+ in around seven hours. On a 32A three-phase CEE socket the result is the same, as the car accepts no more than 11 kW.

Red three-phase CEE sockets are found at industrial sites, workshops, and some commercial marinas. Standard European campsite hookup points use blue single-phase 16A CEE sockets, which cap output at 3.7 kW. At that rate, the 66.5 kWh battery takes around 21 hours for a full charge; the 250+ around 22.5 hours. A campsite blue socket is adequate for a partial top-up during a multi-night stay, but not a practical source for a full charge on a single overnight stop. On a standard domestic socket at 2.3 kW, a full charge takes around 34 hours for the 66.5 kWh variants and around 36 hours for the 250+: relevant only as an emergency fallback, not a regular charging method.
