The UGREEN 40702 solves a common connectivity problem: newer devices increasingly use USB-C ports while many accessories still use the traditional USB-A connector.

The adapter features:

USB-C Male → USB-A Female

Simply plug the USB-C end into your compatible laptop, tablet or smartphone and connect your existing USB-A accessory to the female USB-A port.

2. Up to 10Gbps Data Transfer

• Files from USB flash drives

Actual speeds depend on the USB standard supported by the host device, connected USB accessory and cable.

3. Connect USB-A Flash Drives to USB-C Devices

If your laptop or smartphone only has USB-C ports, you don't need to replace all your existing USB-A flash drives.

The UGREEN 40702 allows you to connect a conventional USB-A flash drive directly to a compatible USB-C port.

This is especially useful for quick file transfers between smartphones, tablets and USB storage devices.

With OTG-supported devices, you can connect accessories such as:

• Other compatible USB peripherals

OTG functionality depends on the USB-C host device and its operating-system support.

---

5. Ideal for Modern Laptops

Many modern laptops have moved toward USB-C connectivity and may offer only a limited number of traditional USB-A ports.

The UGREEN 40702 gives you a convenient way to continue using older USB-A accessories.

UGREEN states that the adapter is designed to withstand up to 10,000 plug/unplug cycles under its testing conditions.

This makes it suitable for users who frequently connect USB drives and accessories.
