In 2005, about 3.3 million vehicles bought that 12 months included a minimum of one USB port. Twenty years later, greater than 200 million vehicles have embedded connectivity shops (USB-A), and as of late, a good portion of them have USB-C ports. Some autos have as many as 9 ports! Even many newer-model bikes have USB shops.

Often located on the entrance or rear consoles (and generally contained in the glove compartment), USB ports supply greater than only a method to cost units. They permit music playback, telephone connectivity, entry to navigation methods, and extra. I’ve put collectively a couple of widespread — and possibly not-so-common — methods you may make the most of the ports in your automobile, together with some useful notes.
First, it is necessary to know that some USB ports are designed for charging whereas others could solely assist information switch. Most will present a measly output of 0.5 to 1 amp — barely sufficient to trickle-charge your telephone for those who’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 ability of your car’s 12-volt port (previously referred to as the cigarette lighter socket). Most 12 V ports are rated at 10 amps, providing a method 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
A cheap answer is to choose up a car charger; even high-quality chargers are sometimes underneath $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 might 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 telephone interplay by way of the infotainment system to make calls, view maps, and work together with voice assistants. Whether or not you employ “Hey Siri” or “Hey Google” prompts to ask your telephone for instructions (“Take me to…”) or to textual content a pal (“Ship an SMS to…”), these good methods are typically dependable for answering non-generative AI questions.
What does this must do with USB ports? Bear in mind, even when a port’s major function 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 through Bluetooth, hardwiring your telephone to your automobile’s smartphone integration system is a method to energy your telephone whereas additionally exploiting its “smartness.”

There are different benefits to utilizing a USB port to attach along with your car’s cell gadget projection methods. Specifically, it gives a extra secure connection, larger audio constancy, and diminished potential for interference.
What’s firmware? Consider it as a sort of bridge between the {hardware} and software program configurations inside good electronics. All fashionable 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 a number of 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, comply with the prompts in your unit head show, normally beginning with the “System Updates” possibility.

The precise steps to put in these updates through USB will range relying in your automobile’s make and mannequin. Additionally, you must format the USB drive in a file system appropriate with the car. Relying in your automobile’s producer, this may very well be exFAT or FAT32. Happily, most store-bought USB flash drives come pre-formatted with the flexibility to learn these information.
The second commonest use of automotive USB ports is for listening to music.
I like music as a lot as I 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 automobile’s solely USB-C port, which by the way is the one information port in that automobile. This fashion I can hearken to my fastidiously curated songs, nevertheless it’s sort of a bummer that I would like to make use of that port for both the MP3 participant or to interface with my telephone, not each.
Additionally: Is your Roku TV spying on you? Probably, but here’s how to put an end to it
Nonetheless, your car could have a USB port that transfers information and means that you can play music straight from a USB stick or flash drive. That drive should be formatted in a file system that your automobile helps, like FAT32 or NTFS. And you must be certain the information are saved in in style audio codecs equivalent to MP3, AAC, and OGG. Some automobile head models require you to manually navigate to the music file location on a USB drive. Others routinely detect music information and play them instantly. Within the latter case, you are greatest off taking part in all of the songs in your library on random mode.
Possibly it is thought of garish, however I’ve by no means had a passenger in my automobile 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 through USB by way of the adapter in my automobile’s 12 V port. The one downside is the truth that these strips include wires. Free wiring actually diminishes the general aesthetics, a minimum of in daylight, so you need to set up them discreetly and cleverly to cover the wires if in any respect doable.
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 by some means illuminate wirelessly, I will be its first buyer.
Will vehicles do away with USB-A ports quickly?
My brother-in-law’s 2021 Honda Accord Touring has a luxurious characteristic that almost all vehicles don’t: a wi-fi charging pad under the dashboard within the middle console the place you may toss your telephone 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 automobile’s infotainment system, so it additionally transfers information.
With that tech showing in a four-year-old automobile, it is simple to foresee Qi wi-fi charging turning into an trade normal in midrange autos. (The time period “Qi,” by the best way, derives from a Chinese language phrase which means “power circulate,” 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 expertise is turning into extra prevalent, nevertheless, it stays unlikely to utterly 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 is likely to be on the horizon. For now, although, the USB ports in your automobile nonetheless supply benefits in charging velocity, information switch capabilities, and common gadget compatibility.
