About the UGREEN US154 (30701)

The UGREEN US154 is a USB-C male to USB-A 3.0 female OTG adapter designed for compatible USB-C host devices. It supports USB 3.0 data transmission up to 5Gbps and backward compatibility with USB 2.0 and USB 1.1 accessories. The adapter features a short 15cm cable and aluminum-alloy connector housing, making it convenient for connecting USB flash drives, keyboards, mice, card readers and other supported peripherals. USB OTG or host-mode support is required on compatible smartphones and tablets.

Design & Performance

USB-C to USB-A OTG Connectivity

The UGREEN US154 converts a compatible USB-C host connection into a standard USB-A female port. This allows users to connect existing USB-A accessories to laptops, tablets and smartphones that may not have a full-size USB port.

USB OTG support is required when connecting peripherals to a smartphone or tablet. The adapter does not add USB host functionality to a device that lacks it.

USB 3.0 Data Transfer up to 5Gbps

The UGREEN 30701 supports USB 3.0 data transfer with a theoretical maximum interface speed of 5Gbps. It is suitable for copying documents, photographs, videos and other files between a compatible USB-C host and USB storage device.

Actual transfer performance depends on the connected USB device, host port, file system and operating conditions. USB 2.0 and USB 1.1 peripherals operate at their supported lower speeds.

Connect Flash Drives and Storage Devices

The adapter makes it possible to access supported USB-A flash drives and compatible storage accessories from a USB-C computer or OTG-capable mobile device. Users can transfer files, open documents and manage portable storage without moving everything through cloud services.

External hard drives and other power-demanding peripherals may require more power than a phone or tablet can supply. A suitable powered USB hub or self-powered storage device may be necessary.

Support for Keyboards, Mice and USB Accessories

The USB-A female connector accepts compatible keyboards, mice, wireless receivers, card readers and other supported USB peripherals. This can help users work with familiar computer accessories on USB-C laptops or tablets.

Some specialized peripherals require additional drivers, applications or host permissions. Compatibility depends on the connected device and operating system rather than the adapter alone.

Flexible 15cm Cable and Aluminum Housing

The UGREEN US154 features a short 15cm flexible cable that provides convenient space between the USB-C host port and the attached USB accessory. This design reduces direct mechanical leverage on the USB-C connector compared with a rigid one-piece adapter.

Its aluminum-alloy connector housing and compact black construction are suitable for daily use, travel and portable workstation setups. The adapter can be carried easily in a laptop bag or accessory pouch.

Plug-and-Play Operation on Compatible Devices

The UGREEN US154 normally requires no dedicated adapter driver on supported computers and mobile devices. Connect the USB-C male plug to the host, then insert a compatible USB-A peripheral into the female port.

The adapter is designed for USB data and peripheral connectivity. It does not provide USB-C Power Delivery charging, HDMI or DisplayPort video output, Ethernet connectivity or multiple independent USB ports.

Who It’s For

Smartphone Users: Access supported USB flash drives through USB OTG. Laptop Owners: Connect traditional USB-A peripherals to USB-C computers. Students: Transfer documents and use compatible keyboards or mice. Office Professionals: Connect USB storage and everyday accessories. Travelers: Carry a compact converter for existing USB-A devices. Home Users: Continue using supported USB peripherals with newer USB-C devices.
