The tiny device connects to your Android smartphone through the micro USB 2.0 connector to enable microSD card reader functionality. You can use it whenever you need to transfer files from your phone to a computer or from the computer to the phone.
The card reader requires the Micro USB OTG connector and is compatible with all microSD cards. You can use it with your Android smartphone, as well as with Android tablets.
Another cool feature is the one that allows you to playback images and videos on the phone directly. This way you can check on the phone if to reshoot videos or replace some photos, without transferring them to the computer first. Plus there is a storage slot for an additional microSd card. A LED indicator tells when data is transferring, while the device is also waterproof and dustproof.
