Product description The idea for this product More and more new laptops, ultrabooks will be equipped with a USB C port, not a standard USB port. We enjoy the portable super thin design. But we soon found it a bit annoying and lowered our work efficiency because we couldn't use standard USB mouse, pendrive directly on MacBook Type-C or Ultrabook. This little gadget will solve your problem by adding a USB port to your USB C-enabled devices, so you can connect standard USB peripherals such as a flash drive, USB hub, printer cable, card reader, keyboard or mouse, etc. to your USB-c smartphone, tablet, Macbook, laptop for data transfer. For USB C OTG supported phones, this converter can turn on your phone as a host, then you can watch movies or music directly from the USB flash drive. You can also play with the USB game holder, type with the keyboard, etc. Much more convenient operation brings you better work and entertainment. Note 1. For a better experience, we suggest you use this product for data transfer but not for charging. 2. For with OTG function, please make sure your device is OTG supported. 3. In the case of the Nintendo Switch, you can connect a mouse or keyboard with the OTG function, but not a flash drive/HDD to the Nintendo Switch.
