What Can a Lightning Cable Charge?

Apple's Lightning cable acts as an iPhone and iPad charger cable, and can also be used for charging other Apple devices and accessories. Let's go over which Apple devices use the Lightning cable, and how to use a Lightning charger.

Lightning cable-compatible Apple devices include:

  • iPhone 5 and later
  • iPad 4 and newer (see note below)
  • Apple Pencil (1st generation)
  • iPod Touch (5th generation and later)
  • iPod Nano (7th generation)
  • AirPods charging case
  • AirPods Max
  • BeatsX
  • Beats Solo Pro 
  • EarPods 
  • Apple TV remote
  • Siri Remote
  • Magic Keyboard
  • Magic Mouse 2
  • Magic Trackpad 2

Lightning cables can also connect to and charge compatible non-Apple devices, and to peripherals like battery chargers, power adapters, cameras, and more. While the USB side of a Lightning cable must be facing the correct way to plug in, the Lightning port side can, conveniently, face either way.

Note: While most Apple devices use a Lightning-to-USB connection, newer iPads, including the fifth-generation iPad Air, and the third, fourth, and fifth-generation iPad Pro, use a USB-C connector or even a USB-C connector with support for Thunderbolt/USB 4. 

Pro tip: If you get water into the Lightning port of any of the above devices, we have a fix for the Liquid Has Been Detected in Lightning Port problem. 

How to Charge with a Lightning Cable

You can use this Apple charger for your iPhone and other devices directly from an outlet by using a power or Lightning adapter like the 5 W USB power adapter pictured below. There are many other types and models of power adapters available for USB, including 12 and 30 W models, and even power adapter kits for world travelers.

If you're on the go and don't have access to an electrical outlet, don't worry; you can use a power bank for your iPhone, or even purchase a power bank for your iPad or Mac. You can also power up one device with a Lightning port from another with a USB port, although this will be a slower charge than you'd get from an outlet. For example, you can charge your iPhone from an iPad. If you have a newer iPad with a USB-C port, you'll need a Lightning to USB-C cable.

Most newer cars have a USB port you can use with a Lightning cable to power your iPhone, although a larger device like an iPad or MacBook may draw more power than the port is capable of providing.  

Lightning Cable, Connected Devices & Adapters

Apple's Lightning cable can send and receive data, so you can use them for a variety of purposes. You can use a Lightning connector to download and upload photos to a Mac or PC, as well as upload and download movies and music. You can also use a Lightning cable to back up an iPhone to a Mac and synchronize files between devices. Unless your car supports wireless CarPlay, you'll need a Lightning cable to connect CarPlay to your iPhone, so your car's audio system can receive data from your iPhone. 

Sometimes your Lightning connector needs a little help to connect devices, and there are many types of cords and adapters to help you connect and charge your devices. We won't go over all of them here, but we'll write a more comprehensive article soon! Here are just a few of the many Lightning cable adapters on the market:

USB-C to Lightning Cable

If you want to connect your iPhone to a newer iPad, an older iPad to a newer iPad, or any other Lightning-port compatible device to a USB-C compatible device, this is the cable for you. 

Lightning to 3.5 mm Audio Cable

This adapter is perfect for connecting an iPhone or older iPad to speakers and headphones with miniplug connectors. 

Lightning to Digital AV Adapter

Need to make a presentation and hook your iPhone or iPad up to a projector or HDMI TV? This is the adapter you need!

As few Apple products have a 3.5mm headphone jack, you can also use a dongle with a Lightning connector to plug your headphones in via the Lightning port if you’d like to use wired audio.

The Lightning connector can also transmit audio. Starting with the iPhone 7, Apple ditched the headphone connector in its smartphone lineup. While the rise of wireless headphones and speakers drove Apple's decision, the latest iPhones can be used with a Lightning-to-headphone adapter that connects the devices to headphones with miniplug connectors.
