USB charging in the Mercedes-Benz A-Class depends on what your trim actually carries in the console. On UK cars the socket picture is: 12V accessory socket standard; USB-A + USB-C common on newer trims. That decides whether a cigarette-lighter charger, a USB-C PD hub or nothing is the sensible buy.

What to look for on the listing
- That the charger plug matches what the Mercedes-Benz A-Class actually has (12V socket, USB-A, USB-C, or a mix).
- How much power each port is rated for on its own AND how much the two ports share when both are in use.
- USB-C PD or PPS support if a modern Samsung, Google or Apple device is on the receiving end.
- Cable quality and length, a 100 W-rated charger paired with a 60 W cable delivers 60 W.
Frequently asked questions
What sockets does the Mercedes-Benz A-Class carry in the front?
12V accessory socket standard; USB-A + USB-C common on newer trims. This UK-market car has a 12V accessory socket in the console area and typically at least one USB-A and one USB-C port from the factory; a 12V-to-USB-C PD charger tops up devices the factory ports cannot power fast.
Do I need USB-C PD or is USB-A enough?
USB-A tops out at 12 to 18 W over Quick Charge 3.0. USB-C Power Delivery (PD) supports up to 100 W and is required for laptop-class charging and full-speed iPad or iPhone charging. For any device sold in the last three years, USB-C PD is the standard.
