REVIEW – Is your iPhone or iPad running out of storage space or do you want an easy way to transfer files and back and forth from your iPhone/iPad to your laptop? The PNY DUO LINK is a flash drive with a built-in lightning connector and a USB-A connector so that it can plug into your Apple device and your computer. It can even be used as a charging cable. Let’s check it out.

What is it?

The PNY DUO LINK is a charging cable and flash drive that’s designed especially for the iPhone and iPad that have a lightning connector. It can be used to free up space on your iPhone and iPad by transferring photos, videos, and more to the DUO LINK and then to your computer.

What’s in the box?

Design and features

The DUO LINK USB-A/Lightning cable is slightly over 6 inches long when you unfold it.

It comes with a plastic clip that keeps the cable folded and more compact for travel and storage. The cable itself feels robust with a thick rubber covering and aluminum ends.

The PNY DUO LINK is available in either 64GB or 128GB capacities. So it’s not just a cable that you can use to transfer files back and forth between phones, tablets, or computers. It’s also a flash drive that can hold files.

I performed my testing of the PNY DUO LINK with my iPhone 12 Pro Max and my 13″ MacBook Pro M1.

If you know anything about the 13″ MacBook Pro M1, you’ll know that it does not have a USB-A connector. For this reason, I had to use a dongle in order to connect the DUO LINK to my MB. The PNY DUO LINK also will not plug directly into my 11″ iPad Pro because it has a USB-C connector and not a lightning connector. I think the PNY DUO LINK would be a lot more useful if it had interchangeable connectors for USB-C on both ends as well as USB-A and Lightning. That way it could easily be used with an iPhone, newer iPads, and MacBooks.

The App

To use the PNY DUO LINK with your iPhone or iPad, you need to install the DUO LINK 4 app. This app is the utility that you use to copy files to/from the DUO LINK’s internal memory and it’s also used to back up the iPhone or iPad.

The DUO LINK 4 app has a basic file manager interface that you can use to browse the images, music, documents, and video files on your mobile device. The app allows you to copy single or multiple files for transfer to/from the device and to/from the DUO LINK.

There’s also a backup and restore function but be aware that it will only back up photos, video, music, and contacts and that’s all. It will not back up your device’s settings or applications.

Also note that the flash drive can’t be used in other file manager apps on the iPhone. It won’t show up as an available external memory source.

I tested the DUO LINK copying files to and from my iPhone and the DUO LINK without any issues. I also tested playing video files on the iPhone that were stored on the DUO LINK without any problems. Backing up contacts worked fine too.

Backing up photos and videos from my iPhone to the PNY DUO LINK was incredibly and torturously SLOW and the app didn’t even tell me how much space the files were going to require. It just started the process and then around the 40% mark, it slowed to a crawl and took an hour to get to 50% at which point it crashed because it ran out of room.

For my next test, I plugged the DUO LINK into my MacBook using a USB-A to USB-C dongle and copied all the data that was on the DOU LINK (62GB) to a folder on my MacBook. It took 14 minutes. UGH.

Final thoughts

The PNY DUO LINK is a well-made flash drive for the iPhone and older iPads with lightning ports. It offers a basic set of features that include the ability to charge the device when plugged into a laptop and the ability to transfer media files between the DUO LINK and the mobile device or between the DUO LINK and a computer. You can also play video and music files directly from the DUO LINK to your mobile device and you can back up media files and contacts (IF you have enough room!). If you’re looking for the ability to backup everything on your mobile device, you’ll need to look elsewhere.
