What an Apple car charger does
An Apple car charger is a power adapter that plugs into your vehicle's 12-volt outlet (the socket formerly called a cigarette lighter) and charges your iPhone, iPad, or other Apple device through a USB or USB-C cable. It converts the car's electrical system into the right voltage and current for your device, the same way a wall charger does at home.
Apple sells two main types: the USB-A car charger, which works with older iPhones and iPads that use Lightning cables, and the USB-C car charger, which works with newer iPhones (iPhone 15 and later), iPads, and MacBooks. The USB-C version is faster because it delivers more power — up to 20 watts instead of 12 watts — so your device charges while you drive instead of just staying at the same battery level.
Most car chargers have one port, though third-party versions often have two or more so you can charge multiple devices at once. Apple's official chargers are compact and designed to fit snugly without blocking access to other controls on your dashboard.
Key Takeaways
- Apple car chargers plug into your vehicle's 12-volt outlet and charge through a USB or USB-C cable connected to your device.
- The USB-C model charges faster (20 watts) than the USB-A model (12 watts), and you need the right type to match your device's charging port.
- Your car's electrical system must be running or in accessory mode for the charger to work; it draws power from your battery.
- Third-party car chargers often cost less than Apple's official versions but may charge more slowly or have durability differences.
- Leaving a car charger plugged in when the engine is off can slowly drain your battery over days or weeks.
Which Apple car charger you need
Check your device's charging port to determine which charger to buy. iPhones from the iPhone 15 onward have USB-C ports and need the USB-C car charger. Older iPhones (iPhone 14 and earlier) have Lightning ports and need the USB-A car charger. iPads vary: newer iPad Pro and iPad Air models use USB-C, while older iPad models and iPad mini use Lightning.
You also need the right cable. If you buy Apple's USB-C car charger, it does not come with a cable — you must purchase a USB-C to USB-C cable separately. The USB-A charger also does not include a cable, so you need a USB-A to Lightning cable. This means the total cost of getting a working setup is higher than the charger price alone.
If you own multiple devices with different ports, you have two options: buy two separate chargers, or buy a third-party dual-port charger that has both USB-A and USB-C. Third-party chargers are often cheaper than buying two Apple chargers, though they vary in build quality and charging speed.
How to install and use a car charger safely
Locate your vehicle's 12-volt outlet. In most cars, this is on the dashboard below the steering wheel, in the center console, or on the back of the front seats. Some vehicles have multiple outlets. Insert the charger firmly until you hear or feel it click into place — it should not wiggle or fall out when you tug it gently.
Turn on your car's engine or switch the ignition to accessory mode (the position between off and start). The outlet will only provide power when the engine is running or in accessory mode. Plug your cable into the charger's port, then connect your device. Your phone or tablet should show a charging indicator within a few seconds.
Do not leave the charger plugged in after you turn off the engine. Even when not actively charging a device, a charger left in the outlet can draw a small amount of power continuously. Over several days or weeks, this can drain your car battery enough to prevent the engine from starting. Remove the charger when you exit the vehicle, or unplug the cable from the charger and leave the charger in the outlet but disconnected.
Charging speed and power delivery
Apple's USB-C car charger delivers up to 20 watts of power, which is fast enough to charge an iPhone 15 or newer iPad while you drive. The older USB-A charger delivers 12 watts, which is slower — your phone may charge slowly or stay at the same battery level if you are using navigation, streaming music, or running other power-hungry apps.
Charging speed also depends on your cable quality. A damaged or low-quality cable can reduce the power reaching your device even if the charger is capable of delivering more. If your device charges very slowly, try a different cable before assuming the charger is faulty.
Your device will also charge more slowly if it is hot. Phones and tablets have built-in safety limits that slow charging when the internal temperature rises. On a hot day with the sun beating down on your car, your device may charge at half speed or not charge at all until it cools down. This is normal and protects the battery from damage.
Third-party versus Apple car chargers
Apple's official car chargers cost between $20 and $30, depending on whether you choose USB-A or USB-C. Third-party car chargers from brands like Anker, Belkin, and others often cost $10 to $20 and may offer features like dual ports or faster charging speeds. The trade-off is that third-party chargers vary widely in durability and reliability.
When comparing third-party options, look at the wattage (higher is faster), the number of ports, and customer reviews that mention how long the charger lasted. Some third-party chargers have safety features like overcurrent protection, which prevents damage to your device if something goes wrong. Check the product description to see if this is included.
Apple chargers are designed to work seamlessly with Apple devices and come with Apple's warranty, which covers defects for one year. If your charger stops working within that time, you can contact Apple Support for a replacement. Third-party chargers usually have shorter warranties or no warranty at all, so you may need to buy a replacement sooner if it fails.
Troubleshooting common problems
If your device is not charging, first check that the car's engine is running or in accessory mode. The outlet will not work when the ignition is completely off. Next, make sure the charger is fully inserted into the outlet — it should click and sit flush. If it is loose or partially inserted, remove it and try again.
Inspect the cable for damage like fraying, kinks, or exposed wires. A damaged cable will not charge even if the charger and outlet are working. Try a different cable if you have one available. If the device charges with a different cable, the original cable is faulty and needs to be replaced.
If the charger itself is hot to the touch or makes a burning smell, unplug it when ready and do not use it again. This indicates an electrical fault. If your device still will not charge after trying a different cable and confirming the outlet works, the charger may be defective and should be replaced.
Environmental impact of car chargers
Car chargers themselves have minimal environmental impact — they are small, use no energy when not in use, and last for years. However, the electricity they draw comes from your vehicle's engine, which burns fuel. Charging your phone while driving uses slightly more fuel than not charging it, though the amount is negligible for most trips.
The bigger environmental consideration is the battery in your device. Frequent charging cycles wear out lithium batteries faster, and a worn battery eventually ends up in a landfill or recycling facility. To extend your battery's life, avoid letting your phone get too hot while charging (keep it out of direct sunlight), and try not to charge to 100 percent every time if you do not need to.
When your car charger eventually fails or you upgrade to a new one, recycle the old charger instead of throwing it away. Most electronics retailers and municipal recycling centers accept small electronics like chargers. This keeps the materials out of landfills and allows metals and plastics to be recovered and reused.
Frequently Asked Questions
Can I use an iPhone charger in my car if I do not have a car charger?
No. An iPhone wall charger plugs into a standard electrical outlet and requires 110-volt AC power. Your car's 12-volt outlet provides DC power, which is a different voltage and current type. Plugging a wall charger into a car outlet will damage the charger and possibly your device. You need a charger specifically designed for 12-volt car outlets.
Will a car charger drain my battery if I leave it plugged in?
Yes, over time. A charger left in the outlet draws a small amount of power even when nothing is plugged into it. If you leave it for several days or weeks without driving, it can drain your battery enough to prevent the engine from starting. Remove the charger when you exit the vehicle or unplug the cable from the charger and leave the charger itself in the outlet.
Why does my phone charge slowly in the car even with a fast charger?
Several things can slow charging: using navigation or streaming apps while charging, a damaged cable, a hot phone, or a low-quality charger. Try closing unnecessary apps, using a different cable, and keeping your phone in a cool spot. If it still charges slowly, the charger may not be delivering full power.
Do I need to buy a cable separately if I get an Apple car charger?
Yes. Apple's car chargers do not come with cables. You must purchase a USB-A to Lightning cable (for older iPhones) or a USB-C to USB-C cable (for iPhone 15 and newer) separately. This adds to the total cost of setting up a working car charging system.
Can I charge my MacBook in the car?
Only with the USB-C car charger, and only if your MacBook supports USB-C charging. Newer MacBook Air and MacBook Pro models can charge via USB-C. The 20-watt charger will charge slowly compared to a wall charger, so it is better for maintaining battery level during a drive than for a full charge. Older MacBooks with MagSafe connectors cannot charge from a USB-C car charger.
