USB-C to USB-A OTG Adapter HOCO UA17 Black — USB-C (male) to USB-A (female) OTG adapter

HOCO UA17 Black is a compact USB-C to USB-A OTG adapter that enables direct connection of USB-A peripherals to devices with a USB-C port. Designed for simple plug-and-play use, this small adapter converts a USB-C male plug into a USB-A female socket, allowing data transfer and peripheral connectivity without extra cables. The adapter is intended for smartphones, tablets and laptops that support OTG functionality and provides a convenient way to connect flash drives, keyboards, mice and other USB-A accessories.

Advantages

The HOCO UA17 offers a straightforward, low-profile solution for expanding connectivity on USB-C devices. Its compact form factor makes it easy to carry and attach without blocking adjacent ports. The adapter requires no drivers on most modern devices and supports direct data access from USB-A storage devices as well as operation of common input peripherals. The black finish provides a neutral appearance that matches many devices and cases.

Suitable for

• Connecting USB-A flash drives to a USB-C smartphone or tablet for file transfer
• Using USB-A keyboards or mice with USB-C tablets and laptops
• Accessing external storage for media playback or document editing on mobile devices
• Quick temporary connections of USB-A accessories without carrying extra cables

When it may not be suitable

This adapter only provides a physical USB-C to USB-A connection and relies on the host device supporting OTG (On-The-Go) functionality. It does not supply additional power beyond typical USB OTG limits and is not intended for high-current charging of external devices. It also does not convert between USB protocol generations — performance will be limited to the capabilities of the connected ports and devices.

Key specifications

• Connector A: USB-C (male)
• Connector B: USB-A (female)
• Function: OTG adapter for data transfer and peripheral connection
• Color: Black
• Form factor: Compact, low-profile inline adapter

How to use

Insert the USB-C male plug into the device’s USB-C port, ensuring correct orientation. Plug a USB-A device such as a flash drive, keyboard or mouse into the USB-A female port on the adapter. On devices with OTG support, the host should recognize the connected peripheral automatically; if required, use the device’s file manager or input settings to access storage or configure connected peripherals. Remove the adapter by gently pulling it from the USB-C port when finished.

What to consider before purchase

• Verify that your smartphone, tablet or laptop supports OTG functionality
• Check the power requirements of the peripheral — the adapter does not provide high-current charging
• Confirm that the connected USB-A device is compatible with your host device’s operating system

Usage recommendations

For reliable operation, use the adapter with devices that explicitly list OTG support and avoid forcing large or heavy peripherals that may stress the adapter connection; store the adapter in a protective pocket when not in use to prevent dust or damage to the connectors.
