Although we saw a handful of flash drives appear when iOS began allowing developers to access directly attached external flash drives a couple of years ago, the market quieted down a bit after that.

However, despite the availability of higher-capacity iPhones and cloud-based storage, veteran flash memory maker Kingston clearly feels there’s still a need to be filled here.

Build Quality and Handling

The full metal build of the Bolt DUO gives the product a premium feel, making it solid and robust despite the small size and weight.

The main hardware is finished in a matt metal look with the small bolt logo and aesthetic shaping that makes it easy to insert into both the iOS device or computer

The small rubber case supplied with the Duo comfortably fits around the Duo and in turn can then be attached to a key ring so that it’s always with you.

The case itself is nicely made.

Although the Duo never popped out of the case completely, there were a couple of occasions when connected to a key ring the Lightning side of the Duo did pop out.

In use the connection is straightforward enough, simply plug into the bottom of the iOS device in the same way you would normally attach the charging cable.

Taking a look at the app and you have a selection of choices. The first is to transfer Photos and Videos over to the Bolt.


To start the copying, all you need to do is follow the onscreen instructions, and you can select to keep or delete the files from the iOS once the process is complete.

The two other options are to ‘Capture’ either Photos or video or ‘View’ the files that have been transferred to the Bolt Duo.

Once the Bolt is plugged in, aside from the physical protrusion from the base of your iOS device it’s all very neat.

Duo is designed to work with Photo’s and Videos the process of either copying from the iOS device to the Bolt Duo

Starting the test I downloaded all images from my iPhone to the Bolt, this process took about an hour as there were several hundred images to transfer.

Later backups to the Bolt Duo took far less time.

Reviewing the Photos and videos from the Bolt Duo is all done through the app rather than through iOS’s photo and video apps.

The Bolt app is fast and responsive enabling you to quickly review your images and playback video clips with ease.

As with many apps once you select an image or video clip as well as reviwing you also have the option to share through your list of selected platforms and apps.

The Duo part of the name comes from the dual connectors, Lighting to plug into your iPhone / iPad on one side and USB 3.1 on the other.

The main body of the Bolt Duo is made from metal and weighs in at 7.2g;

The size, like the weight, is small at just 40.7 x 12.2 x 7mm or 65 x 20 x 11mm with the case.

As well as the primary hardware there’s also the app, and this is compatible with any iOS device that runs iOS 9.0 or newer.

Capture Directly to the Bolt

Instead of backing up your photos, you can capture photos and videos directly to the Bolt — as if you’re shooting to an external drive.

That comes in handy if you want to quickly transfer your images or footage to a laptop or desktop computer.

After you’re through shooting, you pull the Bolt out of your iPhone and plug the opposite end into a USB port on your computer (you’ll need an adapter for new USB-C MacBooks), which sees the Bolt as a standard thumbdrive.

You can then drag whatever files you want over files over to the computer’s hard drive.

What’s more?

If you have a camera roll with a massive number of photos, you may have to copy them over in stages.

The good news is that if your iPhone dies in the middle of a “transfer all” session, the Bolt remembers where you stopped copying and continues from where you left off once you start copying again.

But compared to what Apple charges per GB for its iPhone memory bumps, the price doesn’t look so bad. If you shoot a lot of photos and videos with your iPhone, it’s a nice accessory if you can afford it.
