Kingston's DataTraveler microDuo Flash drives provide additional storage in a small, convenient form factor for tablets and smartphones that support the USB OTG (On-The-Go) functionality. The USB OTG standard allows mobile devices to directly connect to supported USB devices. DataTraveler microDuo Flash drives allow microUSB ports, often used for charging devices, to be used as expansion ports for additional storage. 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 these devices gets used up faster than ever. DTDUO Flash drives let 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.
