How to Use a USB with an iPhone
The easiest way to use a USB drive with an iPhone is to use a device designed for this purpose, such as a USB drive with a Lightning cable adapter attached. This device plugs directly into an iPhone with no extra devices. It’s a small, portable, and efficient method to expand your storage space by moving items from your iPhone into external storage so that you can free up space on your iPhone.
Most USB drives for iPhones have their own apps. No two apps are identical so we can’t walk you through each individual process, but we can give you an idea of how this will typically work. Here’s a step-by-step explanation for using a USB drive with your iPhone:
First, download the app that accompanies your USB flash drive. When plugging the flash drive into your iPhone, it may prompt you to download the accompanying app on its own, but if it doesn’t, you can download it from the App Store by searching the device’s name or following the instructions included in the device’s packaging.
If you haven’t already, plug your flash drive into your iPhone.
A message will appear on your iPhone screen. Make sure to tap Allow on that message.
You will be directed to go to the app associated with your flash drive. On that screen, you will likely see information like how much storage is available on your phone and how much is available on the USB. You will also see transfer options. Each USB drive and app will look a little different.
The instructions included with your USB flash drive will be the most useful. We suggest following those instructions about what to do next.
The app will likely ask you if you’d like to delete photos or files you’ve just transported from your phone to the drive. If you are trying to clear up storage on your phone, you will want to delete the items you have just transferred. Otherwise, feel free to choose as you see fit!
Tips for Using a USB Drive with an iPad
Using a USB drive with an iPad is slightly more complicated. Newer iPads allow you to connect an adapter in order to use a USB drive. However, some USB drives require more power than an iPad can offer. Before purchasing a USB drive, ensure that it is compatible with an iPad.
Your iPad allows you to transfer photos from your USB drive to the iPad, but you won’t be able to add any other types of files. You can also transfer photos from your iPad to your desktop, or keep them on the USB flash drive in order to utilize external storage for your iPhone.
iPads have a couple of different ports, which means you will need to know which port your iPad has before deciding which method will work for you. The iPad Pro has a USB-C port. All other iPad generations have a Lightning port. Need to check which iPad you have? Check out our iPad identification article to help you narrow it down.
