The USB port in the new A4 is located inside the center armrest box. The new Audi A4 features a design with three distinct waistlines, paired with a wide front grille and high-definition matrix LED headlights. The interior is equipped with a combination of genuine leather and fabric, carbon fiber interior trim, and multi-color ambient lighting, offering both dynamic and elegant style options. The new Audi A4 comes with the Audi Virtual Cockpit Plus, which displays phone, navigation maps, and more in 3D on a 12.3-inch screen, allowing seamless switching between classic, sport, or dynamic display styles. Additionally, the new Audi A4 is equipped with a B&O sound system and an integrated pre-sense safety system. For the first time, it also includes an Android-based system that seamlessly integrates various commonly used smartphone apps and services.

The new A4 has USB ports in three main locations. I frequently use the ones inside the front armrest—just lift the lid to find two Type-C ports, which are super convenient for charging my phone. There's also a port in the storage compartment below the center console, right in front of the gear lever. Just glance down, and it's visible—I usually plug my USB drive here to play music. For rear passengers, the USB port is located below the rear air vents. Last time, a friend riding in my car even complimented this thoughtful design. A quick reminder: distinguish between Type-C and traditional ports, as the newer models mostly use Type-C, so keep an adapter handy. The ports in the armrest provide a stable CarPlay connection—I use it daily, but be careful not to block them with clutter.

Having driven the A4 for commuting over two years, I'm quite familiar with its USB ports. The most frequently used one is in the storage compartment under the center console - it's perfectly positioned for charging when placing my . The armrest box reveals two Type-C ports, and there's a hidden port beneath the rear air vents where my kid charged his tablet last time. The designer was quite thoughtful - drivers can easily reach the armrest ports without looking down. Charging speed is decent, delivering about 30% battery in half an hour. I always remind friends borrowing my car about port locations, as wired connections remain more reliable for navigation before wireless charging becomes universal.

A couple of days ago, I was driving my buddy's new A4 and looking for the USB ports. There were some right in the center console storage compartment. The front armrest opens with a press, revealing two very obvious ports. The rear design is even more clever, with two ports hidden under the air vents—just reach out and plug in. Nowadays, new cars come with Type-C ports, so I specifically bought a fast-charging cable to keep in the car. In practice, the charging speed is twice as fast as using a cigarette lighter adapter, and CarPlay runs smoothly without any lag. I heard the top trim has ports in the rear armrest too, but unfortunately, my car didn't come with that. The ambient lighting near the charging ports is a practical touch—no fumbling in the dark when plugging or unplugging cables at night.

As a dad, I'm most satisfied with the rear USB design. The location below the air vent is just right for my child to reach while sitting in the car seat. I keep a small USB drive with children's songs in the front armrest compartment - just open the cover to play music directly. The interface in the dashboard storage compartment is for temporary charging. Audi's interface layout is very reasonable this time - completely sufficient for charging phones and tablets during long trips. I heard the 45 high-power version even has an additional set of interfaces in the armrest. The unified Type-C interface is very convenient, eliminating the need to carry different cables. The only thing to note is to avoid spilling drinks into the interfaces - cleaning them can be quite troublesome.

The new A4's USB-C ports support up to 27W power output, and I frequently test charging speeds. The port inside the front armrest charges the fastest - connecting my for navigation while charging for half hour can replenish 30% battery. The port in the center console storage compartment works perfectly for dashcams with stable power supply and concealed wiring. The two ports near rear AC vents have slightly lower power but suffice, ideal for charging kids' tablets. Purchasing a PD fast-charging cable doubled charging efficiency. Note the small dust covers beside ports - be cautious about moisture during rainy days. For CarPlay connection, using original cables is recommended as friends often experience disconnections with generic cables.
