UGREEN USB-C OTG adapter, 15 cm

Getting the most from it

When a USB-C device has no USB-A port, this short UGREEN OTG adapter gives you a way to connect compatible USB-A accessories without replacing them. Plug its USB-C male connector into a phone, tablet or laptop, then attach a USB-A device such as a flash drive, keyboard, mouse or game controller. For example, you could connect a USB drive to an OTG-enabled phone to access files or play a movie from the drive, rather than copying it onto the phone first. The cable is 15 cm long, so it takes little room in a bag, though that short reach may be awkward if your device and accessory need to sit farther apart.

Why it’s worth it

Its main appeal is practical reuse: a USB-C port can work with older USB-A gear, including USB 3.0, 2.0 and 1.0 devices listed in the product details. That is useful if you already own a keyboard or storage drive and do not want to buy a new USB-C version just for occasional use. The adapter is also listed as supporting data transfer up to 5Gbps. Treat that as a maximum rather than a guaranteed transfer rate, the connected device and its USB standard will affect the result.

If you prioritize carrying one small adapter for a few familiar accessories, this compact cable makes more sense than buying replacements. If you prefer a longer cable or need several ports at once, its single USB-A socket and 15 cm lead are limiting. It suits you if your USB-C device supports OTG and you want to connect one USB-A accessory at a time. It isn't for you if you need a hub, a longer run, or a way to add permanent internal storage: connecting an external drive provides access to its files, but does not increase the device’s built-in capacity.

Key features

The adapter has a USB-C male connector and a USB 3.0 A female port, with a stated transfer rate of up to 5Gbps. UGREEN lists use with OTG-enabled USB-C phones and tablets, as well as Thunderbolt 3 laptops. Compatibility is not determined by the connector alone, though: the host device must support the relevant OTG or peripheral connection, and the accessory must work with that device. The product name lists recent iPhone, iPad, Galaxy and MacBook families, but the details provided do not confirm every model or accessory combination individually.

The manufacturer also describes the cable as tested for 15,000 bends. That may be reassuring for an accessory that gets packed and unpacked, but it is not a reason to treat the lead as indestructible. Based on the listed details, its strongest case is straightforward USB-A connectivity in a small format, not extra ports or a long cable run.

When to choose it

Choose this adapter if the main job is connecting one USB-A drive, keyboard, mouse or controller to a compatible USB-C device, and a compact 15 cm cable suits your setup. Before choosing, check that the host supports OTG or the intended USB accessory, a matching USB-C port by itself does not establish compatibility. For frequent desk use with several peripherals, a multi-port hub or a longer cable may fit better. For occasional file access or a single accessory on the go, this UGREEN adapter keeps the setup simple without asking you to replace working USB-A devices.
