When your phone’s storage is full: With WeChat taking up 90GB and your photo library storing another 30GB of videos, your iPhone pops up a ‘Low on Storage’ warning. You don’t want to delete your chat history, nor do you want to pay a premium for iCloud—simply plug this card reader into your phone, and your TF card becomes a portable storage drive. Back up your photos and videos with a single click, and free up space on your phone instantly.
On business trips: Your MacBook only has a Type-C port, so you can’t read a USB stick to watch films in your hotel room; or perhaps you’ve shot 4K footage on your iPhone but can’t export it to send to your team. A single card reader works with all your devices, making file management on the go as easy as drinking a glass of water.
Mobile photo editing for photographers: Is your camera’s SD card full? Simply plug it into your iPad Pro or Android phone to select, edit and share photos on social media whilst travelling – no need to wait until you return to your hotel to import them onto your computer.
Product Details
USB 3.0 2-in-1 OTG card reader, designed for users who need to transfer data across devices and operating systems. It features dual Lightning and Type-C ports alongside a TF (MicroSD) card slot, compatible with iPhones, iPads, Android phones and laptops. The USB 3.0 interface offers transfer speeds of up to 5Gbps and supports TF cards of up to 512GB, allowing you to read and write files at high speed in any situation.
Plug-and-play functionality is the standout feature of this card reader. No drivers or additional apps are required; once inserted, the system’s native file manager automatically recognises it, allowing you to browse and copy photos, videos and documents straight away. There is no learning curve and no hassle with device recognition.
Many users who switch between ecosystems (Apple + Android/Windows) have long been searching for an all-in-one card reader that eliminates the need to carry countless adapters. This product offers a simple and efficient solution: small enough to attach to a keyring, yet capable of resolving all the pain points associated with cross-device file transfers.
5Gbps True High-Speed Transfer: Utilising the USB 3.0 protocol, it ensures exceptionally smooth reading of large-capacity photos and 4K videos. Compared to card readers from the USB 2.0 era, speeds are nearly 10 times faster, allowing hundreds of RAW photos or high-definition films to be copied in a matter of minutes.
Ultra-portable card-style design: With ultra-compact dimensions of 38mm × 11mm—roughly the size of a USB stick—the device fits easily into a jeans pocket, wallet compartment or front pocket of a rucksack, making it ideal for business trips and travel without any hassle.
