SMUGDESK 20cm USB-C Male to USB 3.0 Female OTG Adapter Cable

SKU CH-865Y-RT8S9

A 20 cm adapter cable adds a USB 3.0 female port to USB-C devices, supporting 5 Gbps data transfer and OTG for flash drives, keyboards and mice

  • 5Gbps data speed cuts large-file transfer time
  • OTG support connects flash drives, mice, keyboards directly
  • 20cm length prevents tangling while keeping reach
  • Plug-and-play design works without driver installation
  • Reinforced connectors resist wear from frequent plugging

20cm USB-C to USB 3.0 OTG Adapter

This short adapter cable converts a USB-C port into a standard USB 3.0 female socket for connecting flash drives, keyboards or mice. It is intended for users with Type-C equipped smartphones, tablets or laptops who need quick access to legacy USB peripherals without carrying a bulky hub. The 20cm length keeps the setup compact for desk or mobile use. No driver installation is required for immediate operation.

OTG Function Enables Direct Peripheral Access

The built-in OTG support lets a host device read USB flash drives, card readers, mice and keyboards directly through the adapter. This removes the need for a separate OTG dongle or powered hub when transferring files or using input devices on the move. Plug-and-play behaviour means the connection works as soon as the cable is inserted. The moulded connector housings are reinforced to withstand repeated insertion cycles.

5Gbps USB 3.0 Interface Limits Transfer Speed

The adapter operates at the USB 3.0 maximum of 5Gbps, so large file copies will be constrained by that bandwidth ceiling. Actual throughput depends on the host controller, the attached storage device and cable quality, so sustained rates will often be lower. The short 20cm cable reduces signal loss but cannot overcome the protocol’s inherent speed limit. Users needing faster transfers would require a USB 3.1 or USB 3.2 Gen 2 connection instead.

Questions about this item

How often will the reinforced connector joints on this 20cm cable need inspection or replacement under normal daily use?

The reinforced joints are moulded to resist bending stress from frequent plugging and unplugging, so no scheduled inspection or replacement is required under normal daily use.

What limits sustained 5Gbps data transfers on this adapter when copying large files continuously?

Sustained throughput is limited by the USB 3.0 interface specification and the thermal capacity of the compact 20cm cable assembly during prolonged high-speed transfers.

Does the adapter generate noticeable heat or draw extra power when left connected to a laptop all day?

The adapter is passive with no active electronics, so it adds negligible heat and draws only the minimal power required by the attached USB 3.0 peripheral.
