Overview
The UGREEN USB C to USB Adapter (2 Pack) is a compact OTG converter designed to connect traditional USB-A devices (such as flash drives, keyboards, or external hard drives) to modern USB-C or Thunderbolt ports. With support for up to 10Gbps data transfer and broad compatibility across laptops, tablets, and smartphones, it aims to offer a practical solution for users navigating the transition from USB-A to USB-C.
Sold as a two-pack, this adapter focuses on portability, durability, and everyday convenience rather than advanced charging or display capabilities. Below is a balanced evaluation of its performance, design, compatibility, and real-world use.
Build Quality & Design
The adapter features a compact aluminium alloy housing. The metal construction gives it a solid feel and provides better heat dissipation compared to plastic alternatives.
Key design highlights:
-
Ultra-small footprint (17.6 × 14.6 × 7.2mm)
-
Slim enough to sit side-by-side with other ports
-
Scratch-resistant metal casing
-
Rated for up to 10,000 plug/unplug cycles
Its minimal size makes it ideal for laptops with closely spaced ports. However, as with most ultra-compact adapters, its small size also means it can be easy to misplace.
The finish feels clean and professional, suitable for both office and personal setups.
Data Transfer Performance
The adapter supports USB 3.2 Gen 2 speeds up to 10Gbps, provided:
-
The host device supports 10Gbps
-
The connected USB-A device supports the same speed
-
The cable length does not exceed recommended limits (under 1 metre for best results)
In practical terms:
-
Large files transfer quickly when paired with compatible SSDs
-
Performance is noticeably faster than USB 2.0 adapters
-
For standard flash drives, speeds are limited by the drive itself
For everyday file transfers — documents, photos, videos — performance is consistent and stable.
It’s important to note that this adapter supports data and charging, but not video output. It does not convert USB-C to HDMI or DisplayPort.
Charging Support
The adapter supports up to 2A charging, which is suitable for:
-
Charging smartphones
-
Powering small accessories
-
Supplying power to USB peripherals
However, it does not support high-wattage laptop charging. It is intended for accessory connectivity rather than full device power delivery.
Compatibility
The adapter works with a wide range of USB-C and Thunderbolt devices, including:
-
iPhone 15 and iPhone 16 (USB-C models)
-
MacBook Pro
-
MacBook Air
-
iPad Pro
-
Samsung Galaxy S23
It also supports OTG functionality on compatible Android devices, allowing direct connection of USB drives, keyboards, or mice.
The slim connector design allows use with many phone cases up to 2mm thick, though bulkier protective cases may need removal.
Everyday Use Scenarios
This type of adapter is particularly useful for:
-
Connecting older USB-A flash drives to USB-C laptops
-
Using USB-A keyboards or mice with newer MacBooks
-
Transferring files between a USB-A external drive and a USB-C phone
-
Expanding connectivity while travelling
Because it is plug-and-play, there are no drivers or setup steps required.
For users transitioning from older USB-A laptops to modern USB-C devices, this adapter helps extend the lifespan of existing accessories.
Durability & Longevity
UGREEN claims up to 10,000 insertion cycles. While real-world longevity depends on usage conditions, the reinforced aluminium housing appears more robust than budget plastic alternatives.
Frequent travellers or office users who plug and unplug regularly may benefit from this more durable construction.
However, like all small adapters, strain from heavy cables hanging off the port could eventually affect the connection. Using lighter cables reduces stress on both the adapter and host port.
Pros
-
Supports up to 10Gbps data transfer
-
Solid aluminium build quality

Charging limited to 2A (not high-power delivery)
-
Easy to misplace due to small size
-
Performance depends on connected device capabilities
Who It’s Best For
Ideal for:
-
Laptop users with USB-C only ports
-
Students and office workers
-
Travellers needing compact adapters
-
Users upgrading to USB-C devices but keeping older accessories
Less suitable for:
-
Users needing display output conversion
-
High-wattage laptop charging needs
-
Complex multi-port docking requirements
Overall Verdict
The UGREEN USB-C to USB-A Adapter (2 Pack) delivers exactly what it promises: a reliable, compact bridge between modern USB-C ports and traditional USB-A devices. Its aluminium construction, high-speed data capability, and universal compatibility make it a practical everyday accessory.
It does not attempt to replace a full docking station or high-power charging solution. Instead, it excels as a simple connectivity tool that extends the usefulness of existing peripherals in an increasingly USB-C-centric world.
In summary: a compact and dependable adapter set that offers fast data transfer and broad compatibility for users navigating the USB-C transition.
