The Dreamscreens MicroSD and SD card reader comes as a two-pack, giving you a reader for every setup, one at your desk, one in your bag, one at home and one at the office. Never be caught without a way to access your cards. Both SD and MicroSD slots are active simultaneously, so you can transfer files from two cards at once or keep both formats accessible without swapping. The USB 3.0 interface delivers transfer speeds up to ten times faster than USB 2.0, moving large photo and video files quickly without tying up your computer. Card format support covers the full range, SD, SDHC, and SDXC in the standard slot, and MicroSD, MicroSDHC, MicroSDXC, and TF cards in the MicroSD slot. Whether you're pulling footage from a camera, drone, action cam, dashcam, or mobile device, the OTG30 handles it without adapters or workarounds. Setup requires nothing beyond plugging in. The reader is self-powered through the USB connection with no external power source needed, and no software installation is required on any supported platform. Compatible with Windows XP, 7, 8, 10, and 11, Mac OS, and Linux, it works across virtually every computer setup without configuration. The compact form factor fits easily in any bag or laptop case, making it a practical everyday carry for photographers, content creators, and anyone who regularly works with memory cards.
