Mercedes A-Class PHEV charging cable

The Mercedes-Benz A-Class PHEV covers the full range of plug-in hybrid variants of the fourth-generation A-Class, available as the five-door hatchback (W177) and the four-door saloon (V177). All versions pair a 1.33-litre four-cylinder turbocharged petrol engine with an electric motor integrated into the 8-speed dual-clutch gearbox, producing a combined 218 hp and 450 Nm at the front wheels. A 15.6 kWh lithium-ion battery (approximately 11.5 kWh usable) sits between the rear axle and the fuel tank, delivering a WLTP electric range of 56–70 km (35–44 miles), with 0–100 km/h in 6.6 seconds for the hatchback and 6.7 seconds for the saloon. The A-Class PHEV was introduced in 2019 and received a significant facelift in 2023. Pre-facelift models (2019–2022) came with a 3.7 kW single-phase onboard AC charger as standard, with 7.4 kW single-phase available as a paid option. From the 2023 facelift onward, the charger was upgraded to 11 kW three-phase as standard, with 22 kW three-phase available as an option. DC rapid charging at up to 24 kW via CCS2 was a paid option across both generations. The Type 2 charging port is on the right rear flank across all versions and body styles.

Charging times at a wallbox

On pre-facelift cars with the standard 3.7 kW onboard charger, a full charge from near-empty takes approximately three and a half hours. With the optional 7.4 kW charger fitted, this drops to around one hour 45 minutes. On facelift models with the standard 11 kW three-phase charger, a compatible three-phase wallbox completes a full charge in approximately one hour 10 minutes. On a single-phase home wallbox with a correctly rated cable, the same charge takes approximately one hour 45 minutes at 7.4 kW. In daily use most drivers top up from a partial state rather than from empty, so real-world sessions are shorter across all versions.

Which cable to use

Cable choice depends on the charger fitted to your car and the type of wallbox at home.

For pre-facelift cars with the standard 3.7 kW charger: the onboard charger is natively capped at 16A single-phase. An 11 kW Voldt® Type 2 cable delivers 16A per phase and feeds this car its full 3.7 kW without restriction. A 22 kW cable is the forward-looking option for a future vehicle with a higher charge rate.

For pre-facelift cars with the optional 7.4 kW charger: the car requires 32A on a single line to reach its full rate. An 11 kW three-phase cable caps the session at 16A = 3.7 kW, halving the charge speed. A 7.4 kW single-phase cable or a 22 kW three-phase cable (32A per phase) is required for the full 7.4 kW.

For facelift models with the 11 kW three-phase charger: an 11 kW cable is the correct match at any three-phase wallbox or public AC post. On a single-phase home wallbox, the same bottleneck applies: an 11 kW cable restricts output to 3.7 kW. A 22 kW cable carries 32A per phase and delivers the full 7.4 kW from a single-phase supply. For facelift cars with the optional 22 kW charger, a 22 kW cable is the only choice that unlocks the car's full AC rate.

Across all generations and charger configurations, a 22 kW cable is the single most versatile choice: it handles 3.7 kW, 7.4 kW, 11 kW, and 22 kW without compromise and future-proofs the purchase.

Cable length

The inlet is on the right rear flank, so reversing into a bay puts the port closest to the post. A 6-metre cable covers most home wallbox setups. An 8 or 10-metre cable suits garages or driveways where the car parks further from the charge point. For workplace charging and car parks where the post position varies, lengths from 10 m upward remove any concern about reach, and Voldt® supplies cables up to 40 metres for installations where a longer run is genuinely needed.

Portable charging with a CEE charger

The Voldt® portable CEE charging cable is a practical option at workplaces, workshops, and industrial sites with CEE sockets.

On a 32A three-phase CEE socket: pre-facelift standard (3.7 kW) cars charge in around three and a half hours; pre-facelift optional (7.4 kW) cars charge in around one hour 45 minutes; facelift 11 kW cars charge in around one hour 10 minutes; facelift 22 kW cars charge in under an hour. On a 16A three-phase CEE socket: pre-facelift single-phase models draw one phase at 16A = 3.7 kW; facelift three-phase models draw 11 kW. On a 16A single-phase CEE socket (3.7 kW): all variants charge at 3.7 kW, taking approximately three and a half hours.

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 and result in the three-and-a-half-hour charge time noted above. For this battery size, a campsite overnight stop is entirely practical at that rate. On a standard domestic socket at 2.3 kW, a full charge takes around five hours, making an overnight plug-in at a holiday rental or relative's home a straightforward option.
