To charge your phone in the car, plug it into a powered USB port or use a compatible USB charger in the car’s 12 V socket. A built-in wireless pad also works with a compatible phone. Charging this way is fine for regular use. Keep the phone cool, especially when navigation, charging and direct sun are warming it at the same time.
Choose the right way to charge
| Charging option | When to use it | What to check |
|---|---|---|
| Built-in USB port | Everyday charging or wired CarPlay and Android Auto | Check which port supports data and how much power it supplies. |
| USB charger for a 12 V socket | An older car without USB or a built-in port that charges too slowly | Match the charger to the socket and the phone. Check the wattage for the port you’ll use. |
| Wireless pad or powered mount | Charging without plugging a cable into your phone | Check phone compatibility, position and case fit. Watch for heat on longer trips. |
Plug in an iPhone or Android phone
- Find a powered port. Use a built-in USB port or plug a car-rated USB adapter into the accessory socket, sometimes called the cigarette lighter socket.
- Choose a cable that fits both ends. iPhone 15 and later use USB-C. Earlier iPhones with a Lightning port need a Lightning cable. Most recent Android phones use USB-C, while some older phones use Micro-USB. The car or adapter can have either a rectangular USB-A port or an oval USB-C port.
- Use the data port for wired CarPlay or Android Auto. Check the port markings or your car’s manual. Use a cable that carries data and power. A USB charger plugged into the 12 V socket supplies power, so use the infotainment port for a wired connection. Set it up while parked. See our CarPlay setup guide and Google’s Android Auto instructions.
Pick a charger that can keep up with navigation
If your built-in USB port charges too slowly, check your phone’s charging requirements. A compatible USB-C Power Delivery (PD) car charger and cable can provide more power. Some Pixel and Galaxy phones use PPS, a feature of USB PD, for their faster charging modes. Check the specifications for your exact phone. See the iPhone charging guide and Pixel charging guide.
The wattage on a USB PD charger is its maximum output. A compatible phone requests the power it can use. On a multiport charger, check how much power the chosen port can deliver when another device is plugged in. Use a reputable charger rated for the vehicle socket and replace cables or adapters that are damaged. See the USB Power Delivery overview.
Place the phone correctly on a wireless pad
On a typical flat charging tray, put the screen up with the back of the phone against the pad. Center it and check for the charging icon. Follow the car’s manual if the tray has an alignment mark or uses a different position. A magnetic mount needs its own powered charging coil to charge a phone.
If charging starts and stops, check whether the phone supports the pad’s standard, such as Qi. Try removing a thick case or wallet attachment and clear coins, keys or other metal objects from the tray. Use a cable if the pad cannot hold the phone in place or the phone gets too warm. See Apple’s wireless charging guide.
Fix slow charging or a falling battery percentage
- Check whether power reaches the phone. Look for the charging icon. If it never appears, check whether the port is powered and try another known-good cable.
- Compare with and without navigation. If the battery rises with the screen off but drops during navigation, the screen and apps may be using more power than the port supplies. Try a compatible PD charger if your setup allows it. An iPhone can also show Slow Charger when a more powerful charger could help.
- Check for heat. A hot phone can slow or pause charging. Keep it out of direct sunlight and away from heater vents. If you see a temperature warning, pull over somewhere safe before unplugging or moving the phone. Let it cool before charging again. Avoid leaving a phone charging in a hot parked car. See Apple’s temperature guidance.
- Test away from the car. Try a compatible wall charger and cable that you know work. If the phone still won’t respond, follow our phone battery troubleshooting steps.
Check what happens when the car is off
Some ports turn off with the car. Others stay live for a while or work in accessory mode. Check the owner’s manual for your outlet. A powered outlet can draw from the vehicle’s battery while parked, especially if you leave devices connected for a long time. Unplug the phone and adapter when you leave if the outlet stays powered. A charged power bank can help if you need power while parked.
Frequently asked questions
Can charging in the car damage my phone battery?
A compatible car charger is suitable for regular use. Heat can shorten battery life, so keep the phone out of strong sun and let it cool if it displays a temperature warning.
Can I charge my phone while driving?
Yes. Connect it and set your route before driving. Keep the cable clear of the pedals and controls, and use the car’s hands-free controls for navigation or calls.
How can I charge my phone in an older car without USB?
Use a USB adapter rated for the car’s accessory socket. If there’s no working socket, use a charged power bank.
Do I need a separate car charger?
A powered USB port and the right cable are enough. You can also use a compatible built-in wireless pad.
Does the phone go face up or face down on the wireless pad?
On most flat pads, place the screen face up and the back against the charging surface. Center the phone, then confirm it shows the charging icon.
Is wired or wireless charging better for a long drive?
Try a cable if the wireless pad keeps pausing or the phone gets warm. Wireless charging is convenient when the phone stays aligned and charges steadily.
Why does my battery drop even though it says it’s charging?
Navigation and the screen can use more power than a weak USB port supplies. Heat can also slow charging. Compare with a cooler phone and a compatible charger that supplies more power.
Will charging my phone while parked drain the car battery?
It can if the outlet stays powered or the car is in accessory mode. Check your car’s manual and disconnect the phone when you’re done.
