Introduction

The tech world is constantly evolving, and with it, the need for adapters to bridge the gap between older and newer technologies. This review focuses on the US276 (Model Number 50533) USB C to USB 3.0 adapter, promising high-speed data transfer and broad compatibility. I’ve put this little adapter through its paces over the past few weeks, testing it with various devices and workloads to see if it delivers on its promises.

Features

The US276 boasts several key features, including its 5Gbps data transfer speed, compatibility with USB 2.0 and 1.1 devices, and its compact, durable design. The aluminum alloy housing feels premium and the small size makes it incredibly portable. The claimed plug-and-play functionality is a major plus, eliminating the need for drivers. The built-in resistor is also a welcome addition, suggesting a focus on safety.

Performance

I tested the adapter’s data transfer speeds using various files—large video files, numerous photos, and large documents. I consistently achieved transfer rates very close to the advertised 5Gbps when using a USB 3.0 port, a very impressive result. The adapter also worked flawlessly with USB 2.0 devices, indicating good backwards compatibility. There were absolutely no compatibility issues with my MacBook Pro 2018, iPad Pro 2020, and various Android smartphones. I even used it to charge my phone and the speeds were comparable to using the phone’s own charger, confirming that it does indeed work for safe and fast charging.

One point worth noting is that transfer speeds will naturally be lower when connected to a USB 2.0 port. While I did observe this speed reduction, the transfer speeds remained respectable and noticeably faster than with a standard USB 2.0 connection.

Pros & Cons

• Pros: Fast data transfer speeds (close to 5Gbps on USB 3.0), good backwards compatibility, compact and durable design, plug-and-play functionality, reliable charging.
• Cons: While the adapter worked great, the color may not match the product images perfectly. Also, it’s not specifically designed to connect to all wireless devices. It requires a wired connection to work.

Final Verdict

Overall, the US276 (Model Number 50533) USB C to USB 3.0 adapter is a solid performer. It delivers on its promises of speed and compatibility. The compact design is perfect for travel, and its plug-and-play nature makes it incredibly user-friendly. For its price and performance, I highly recommend it to anyone who needs a reliable and fast USB C to USB 3.0 adapter.
