This unassuming gadget could be your saviour if you’ve filled your smartphone or tablet with music and photos. Essentially an SD Card reader, the AirStash A02 can read Secure Digital SD and SDXC storage cards of almost any capacity. However, it also has 802.11n Wi-Fi built in, allowing your iPhone or Android phone to access the contents over an ad-hoc wireless network. Items can be sent to several devices at once too, making it useful for sharing digital content.

The idea is that you can use the internal storage on your smartphone for apps and hive off the photos and other gubbins that you don’t always need to be able to access to the AirStash. Since the iPhone has no card reader slot or USB port, the ability to pull across photos stored on one should be a boon. A dedicated iPhone and iPad app helps you navigate through your photo library.

The AirStash has a USB 2.0 port means you can easily transfer items from your PC or laptop to the device. This same port is used to charge the AirStash. It should last for around seven hours before needing to be recharged.

The Maxell AirStash costs £109 for the 8GB version while the16GB AirStash version is £129. Both are available through
