CABLETIME 3-in-1 USB-C and USB-A SD/TF Card Reader, Up to 312MB/s
3-in-1 USB-C and USB-A SD/TF Card Reader, Up to 312MB/s
A compact file-transfer tool designed for photographers, creators, travellers and everyday users who move photos, videos and documents between memory cards, USB storage, phones, tablets and computers. Its clever split design gives you both USB-C and USB-A host connectivity without carrying separate adapters.
One reader for cameras, phones, tablets and computers
The CB48G/CB49G family bridges old and new devices in one pocket-sized accessory. Use the USB-C side with compatible iPhone, iPad, Android phone, MacBook or USB-C laptop, or use the USB-A side with traditional desktop PCs and notebooks. This makes it particularly useful for transferring camera photos, drone footage, social-media content, work documents and backup files between different devices.
Smart split design
The USB-C and USB-A sections are designed for flexible use across different host interfaces, helping reduce the need for extra dongles when moving between mobile devices and computers.
SD + microSD workflows
Access files from standard SD cards and TF/microSD cards used in cameras, drones, action cameras, dash cameras and other portable devices.
Extra USB 3.0 port
Connect compatible USB storage or peripherals alongside the card-reader function, useful when copying or organising files across devices.
No special app required
Designed for plug-and-play operation on compatible systems. File access is handled through the device's normal file-management interface.
Built for photographers and content creators
Import photos from a camera card to a laptop, transfer drone footage to a tablet, move phone files onto USB storage, or back up media while travelling. The compact aluminum + ABS body is easy to keep in a camera bag, laptop sleeve or everyday tech pouch.
Choose the correct version
CB48G — CT-ACCD3-AG
SD/TF 3.0 version with transfer speed listed up to 160Mb/s. A practical choice for everyday photo, video and document transfers.
CB49G — CT-ACCD4-AG
SD/TF 4.0 version with transfer speed listed up to 312Mb/s. Choose this version when using compatible higher-performance memory cards and host devices.
The actual speed is determined by the selected reader version, memory-card standard and speed rating, host USB interface, device performance and file type. A faster reader cannot make a slower memory card operate beyond the card's own capability.
Typical use cases
Camera photo import
Move photos and videos from compatible SD or microSD cards to a laptop, tablet or phone for editing, backup or sharing.
Drone & action-camera footage
Quickly access footage from removable memory cards when travelling or working away from a desktop setup.
Phone storage management
On compatible USB-C phones and tablets, transfer supported files to cards or USB storage to free device space.
Cross-device file transfer
Use the dual host connectors when your workflow includes both modern USB-C equipment and conventional USB-A computers.
