SanDisk iXpand

From £42 (16GB) Manufacturer SanDisk, sandisk.co.uk

4 At first glance the iXpand looks like an ordinary memory stick, but as well as having a USB port for use with a Mac it also has a Lightning connector for an iPhone or iPad too. SanDisk’s Sync app lets you quickly copy files to or from your iOS devices, and the iXpand even has its own rechargeable battery so that it doesn’t drain the battery on your iPhone or iPad. It’s available from 16GB to 128GB, and is a really handy option for adding extra storage to your iOS kit. Our only complaint is that it has a USB 2.0 interface rather than USB 3.0. Cliff Joseph It’s a shame about the USB 2.0 interface, but the iXpand is still a really useful way to save space on your iOS devices.
