DataTraveler microDuo allows microUSB ports, often used for charging devices, to be used as expansion ports for the additional memory. Ideal for storing large files while traveling, DTDUO gives Plug-and-Play functionality to tablets and smartphones without microSD ports at a lower price per GB than the extra built-in storage on a mobile device. With smartphones and tablets recording HD video and taking higher resolution photos, space on the device gets used up faster than ever. DTDUO lets users move files, photos, videos and more - without plugging into a PC - to offload or backup content. Sharing large files between mobile devices is easier than using online cloud services, and there's no need for a cable to transfer data between the device and a PC.
