(Beware) These adapters are intended for charging and synchronizing your devices, not for video output. Unless used with webcams or to duplicate video files, these adapters do not work for any other types of video signal transmission — namely NO compatibility with cables or converters that come with HDMI, DisplayPort or any other types of interface for video transmission. Absolute compatibility does NOT exist, so is the case with these adapters. (Built for Multiple Devices) The pack includes two types of the most widely used USB converters for charging and data transfer — USB-C to USB-A OTG adapter and USB-A to USB-C adapter, each comes with two counts. Whether you need to charge your phone, sync your tablet, or connect your favorite device to your computer, this converter pack is the perfect solution.
