Unlike optical discs, pen drives come in many shapes, sizes, and capacities. Fortunately, Vinpower takes that into consideration when we designed our USB duplicator. The Vinpower USBShark USB Duplicator series works with virtually any size USB pen drive and can copy asynchronously regardless of the size of the content. So if you need to transfer content from a USB pen drive to multiple other USB pen drives, or any flash device for that matter, Vinpower has the equipment that will make the task incredibly simple, quick, and reliable.
