Kingston's DataTraveler microDuo provides 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 allows microUSB ports, often used for charging devices, to be used as expansion ports for up to 32GB of 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 these devices gets used up faster than ever. DTDUO lets users move files, photos, videos and more - without plugging into a PC1 - 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. DT microDuo is small, lightweight and easy to take anywhere, plus its sleek design complements any mobile device. Its rotating cap protects the microUSB connector from damage.
