In 2005, about 3.3 million automobiles offered that 12 months included at the least one USB port. Twenty years later, greater than 200 million automobiles have embedded connectivity retailers (USB-A), and today, a good portion of them have USB-C ports. Some autos have as many as 9 ports! Even many newer-model bikes have USB retailers.

Normally located on the entrance or rear consoles (and generally contained in the glove compartment), USB ports supply greater than only a approach to cost units. They allow music playback, cellphone connectivity, entry to navigation methods, and extra. I’ve put collectively a couple of frequent — and perhaps not-so-common — methods you may make the most of the ports in your automotive, together with some useful notes.
First, it is vital to know that some USB ports are designed for charging whereas others might solely assist information switch. Most will present a measly output of 0.5 to 1 amp — barely sufficient to trickle-charge your cellphone in case you’re additionally utilizing it for GPS or listening to an audiobook.
The commonest use for automotive USB ports is to cost our smartphones whereas touring. But when you are going to cost any gadget, harness the facility of your car’s 12-volt port (previously often known as the cigarette lighter socket). Most 12 V ports are rated at 10 amps, providing a approach to distribute a great deal of energy to a number of units on the identical time.
Additionally: This touchscreen display adds Apple CarPlay or Android Auto to any car
An affordable answer is to select up a car charger; even high-quality chargers are sometimes beneath $15. With a pair of each USB-A and USB-C ports, you may cost tablets, wi-fi earbuds, digital cameras, transportable air purifiers, or perhaps a laptop computer when you drive — all funneled from one supply. And thru that supply, you could be assured your units are charging at an optimum velocity as a result of the amperage from the “cigarette socket” merely dwarfs that of your different USB hubs.
Most newish autos now assist Apple CarPlay and Android Auto, enabling cellphone interplay by means of the infotainment system to make calls, view maps, and work together with voice assistants. Whether or not you utilize “Hey Siri” or “Hey Google” prompts to ask your cellphone for instructions (“Take me to…”) or to textual content a pal (“Ship an SMS to…”), these sensible methods are typically dependable for answering non-generative AI questions.
What does this should do with USB ports? Keep in mind, even when a port’s main goal is information connection, it will also be used to cost transportable units (albeit weak as that energy stream could also be). Regardless of Android Auto and Apple CarPlay functioning wirelessly by way of Bluetooth, hardwiring your cellphone to your automotive’s smartphone integration system is a approach to energy your cellphone whereas additionally exploiting its “smartness.”

There are different benefits to utilizing a USB port to attach together with your car’s cell gadget projection methods. Particularly, it offers a extra steady connection, larger audio constancy, and diminished potential for interference.
What’s firmware? Consider it as a form of bridge between the {hardware} and software program configurations inside sensible electronics. All trendy units require producer firmware updates to maintain them operating easily. Your car’s multimedia unit is not any exception.
Whereas over-the-air updates can be found in among the latest autos (especially EVs), many nonetheless require USB drives for set up. Sometimes, this entails downloading the firmware file from the car producer’s web site to a USB drive and inserting it right into a car’s information switch port to provoke the replace. From there, observe the prompts in your unit head show, normally beginning with the “System Updates” choice.

The precise steps to put in these updates by way of USB will range relying in your automotive’s make and mannequin. Additionally, it is advisable to format the USB drive in a file system appropriate with the car. Relying in your automotive’s producer, this could possibly be exFAT or FAT32. Thankfully, most store-bought USB flash drives come pre-formatted with the flexibility to learn these recordsdata.
The second commonest use of automotive USB ports is for listening to music.
I really like music as a lot as I really like all tech wi-fi. But I nonetheless have a tiny SanDisk MP3 participant loaded with hundreds of songs in my 2025 Civic. It dangles from a six-inch cable related to my automotive’s solely USB-C port, which by the way is the one information port in that automotive. This manner I can hearken to my fastidiously curated songs, nevertheless it’s form of a bummer that I would like to make use of that port for both the MP3 participant or to interface with my cellphone, not each.
Additionally: Is your Roku TV spying on you? Probably, but here’s how to put an end to it
Nonetheless, your car might have a USB port that transfers information and lets you play music instantly from a USB stick or flash drive. That drive should be formatted in a file system that your automotive helps, like FAT32 or NTFS. And it is advisable to make certain the recordsdata are saved in common audio codecs resembling MP3, AAC, and OGG. Some automotive head items require you to manually navigate to the music file location on a USB drive. Others robotically detect music recordsdata and play them immediately. Within the latter case, you are greatest off enjoying all of the songs in your library on random mode.
Perhaps it is thought of garish, however I’ve by no means had a passenger in my automotive complain concerning the multicolored scintillation of LED strip lights that I put in on the console, sprint, and above the floorboards. I feel it provides a contact of atmosphere and modernity, if not enjoyable.
These LED strip lights are powered by way of USB by means of the adapter in my automotive’s 12 V port. The one downside is the truth that these strips include wires. Free wiring actually diminishes the general aesthetics, at the least in daylight, so it’s important to set up them discreetly and cleverly to cover the wires if in any respect attainable.
Additionally: Your TV’s USB port has an invaluable feature that makes internet outages more bearable
If an formidable firm can produce low cost LED tape lights that someway illuminate wirelessly, I will be its first buyer.
Will automobiles do away with USB-A ports quickly?
My brother-in-law’s 2021 Honda Accord Touring has a luxurious characteristic that the majority automobiles don’t: a wi-fi charging pad beneath the dashboard within the middle console the place you may toss your cellphone to juice it up. (No magnetic mount and no dangerous fumbling with and plugging in cables required.) Extra awesomely, that pad doubles as a Bluetooth connection level with the automotive’s infotainment system, so it additionally transfers information.
With that tech showing in a four-year-old automotive, it is easy to foresee Qi wi-fi charging changing into an business commonplace in midrange autos. (The time period “Qi,” by the way in which, derives from a Chinese language phrase which means “vitality circulation,” and describes how electromagnetic induction transfers energy from a charging pad to a appropriate gadget and not using a bodily cable.) Likewise, we’ll see an uptick in wi-fi information switch inside autos, which has the potential to enhance vehicle-to-everything (V2X) communication and proliferate over-the-air (OTA) updates for varied car methods.

Whereas automotive wi-fi know-how is changing into extra prevalent, nonetheless, it stays unlikely to fully exchange USB ports in autos. Older USB ports, like USB-A, will ultimately be obsolesced in favor of USB-C with PD (energy supply), and a standardized answer for high-speed information switch could be on the horizon. For now, although, the USB ports in your automotive nonetheless supply benefits in charging velocity, information switch capabilities, and common gadget compatibility.
