Kingston DataTraveler microDuo, First Take: USB storage for Android tablets and phones

Summary: If your Android smartphone lacks a MicroSD card slot and supports USB On The Go, this flexible flash drive could solve your storage expansion problem.


Expanding the internal storage of tablets and smartphones has taken an interesting turn with the DataTraveler microDuo from Kingston. This tiny flash drive has both a full-size and a Micro-USB connector, and is compatible with tablets and smartphones that comply with the USB On The Go (OTG) standard.

In theory this should mean you can grab data such as a video or presentation from your PC and deliver it via your Android tablet with ease. You can work with documents stored locally rather than using the cloud — or how about taking your music library with you when you're travelling?

Alternatively you might fancy a DataTraveller microDuo as a backup device for your tablet or phone. If you're not already using the cloud to back up photos and other content that's unique to your phone or tablet, this might appeal.

The DataTraveler microDuo is small, and it comes with a tiny lanyard that's ideal for storing it on your key ring. The USB port flips through 90 degrees to expose Micro-USB connector.

This is all great, and it might particularly appeal if you happen to have a smartphone that lacks MicroSD card support. But USB OTG is not supported by every smartphone and tablet — you'll need to check the device specifications. An Android app called USB Host Diagnostics can help you analyse your device.

The Kingston DataTraveler microDuo is available in 8GB (£7.50), 16GB (£9.90) and 32GB (£16.30) capacities and is backed by a five-year warranty.

  • Actually - you need OTG AND mass storage driver support.

    Google's own Nexus devices all support OTG but Goog actually removed the mass storage drivers just to prevent people from using this sort of thing...
    • adding a mass storage driver

      It is not free, but Nexus Media Importer allows you to read and write to OTG attached flash drives (albeit with some limitations). It does not require you to root your Android device.

      I am doing this with an OTG dongle (looks like a USB type adapter) and any standard USB 2.0 flash drive.

      I need to hunt around and see if someone markets an OTG adapter that has two inputs - one for the flash drive and the second to simultaneously power my Android device for those times when I need to use it as an impromptu netbook for extended periods.

      • Have you tried a powered USB hub?

        Works for me.
    • in case it's useful to some of you

      I use Total Commander with the 99-cent "USB stick plugin" app and a $1.50 USB-on-the-go cable (from on my Nexus 7 (2013) tablet and it works fine with my USB flash drives.

      My Samsung Galaxy S2 didn't need any special plug-ins to support USB-on-the-go flash drives.
  • adata UD320 is the same

    i have had an adata UD-320 32 GB OTG for several months now, works great with my galaxy s4
  • Good idea!

    I think this is a great idea.
