    OTG Card Reader for Android Smartphones (microSD / SD / USB)

    Effortlessly add additional SD™, microSD™, or USB storage to your Android™ 4.0 or later phone or tablet using this OTG Card Reader from Monoprice!

    OTG stands for "On The Go", which is a USB connectivity standard for Android devices. With an OTG adapter, such as this one, you can connect a variety of USB devices, such as PC keyboards, mice, flash drives, etc. This OTG adapter also includes a full-sized SD card slot and a microSD card slot, allowing you to add gigabytes of storage to your phone or tablet.

    The card reader connects to the Android device using a standard micro USB connection. A micro USB female to USB A male adapter is included, which allows you to plug into a PC or Mac® USB port for traditional card reader usage.

    Note that only one of the two card slots can be used at any given time. While you can use the USB port for an input device, such as a keyboard, simultaneously with a storage card in one of the slots, you cannot use more than one storage device (card or USB flash) at the same time when connected to an Android device.

    Will this work with a Samsung Galaxy s7? I have another brand that is not supposed to work with thew Galaxy and it is VERY touchy. It only sorta works.
    A shopper on Jan 7, 2017
    BEST ANSWER: Yes I have Galaxy s 7 and it works perfectly. In files menu it shows information on external SD card and you can share selected images easily.
    Will this card reader work with Samsung Galaxy 3?
    A shopper on Nov 13, 2017
    BEST ANSWER: Yes it will as long as you don't exceed the limitations of the memory size allowed. In other words you can't use a 128 GB card like you can in the newer Galaxy Phones. If I recall correctly the S3 is limited to 32 GB cards.
    Will this work for the Amazon Firestick? Can I plug the firestick's microsd power cable into the microsd slot on this adapter and the firestick will receive power?

    Thinking about getting one of these since I prefer to use real cameras for important events. How do I find the content of the external media in my cell phone?

    Works Great with my Moto X and Camera with RAW files
    What a great product for Android users. It allows you to have a SD card appear as a drive on your phone/tablet.

    You can then copy the files, backup the files, etc.

    This product works on my Moto X with Android 4.4.4 no problems.

    Great solution.

    PROS: This item allows me to download and backup photos from my compact camera. I'm able to copy files from an SD card and upload directly to Google Drive for backup.

    Appears as a USB drive on the phone.

    CONS: You do have to use the proper sequence. This may be an issue with Android not the product.

    1. Plug the SD card into the read.

    2. Then plug the reader into the phone.

    One thing I wished it would allow you to charge/power the phone via the USB port.

    Nice Reader
    The best feature of this reader is that it can be plugged into the phone while the phone is still in it's case. The bonus is the multiple formats that can be used with this reader. The USB adapter is handy also.

    PROS: Easy to use, works with case on.

    CONS: None

    Worked fine with my SamSung Galaxy S7 Fine but...
    It does work with the Galaxy S8 even with the Micro USB connector that comes with the phone.

    Card reader for smart phone
    I was looking for the possibility to send my pictures captured with DSLR camera to the smart phone where I can instantly share photos with family and friends. OTG card reader appeared to be the chepest solution. It is small, easy to carry with the camera. It works perfectly. Now I can share pictures even in the field. I would highly recommend this product to photography enthusiasts.

    Bought it as gift for someone who owns Samsung Note 5 who needed to add external storage. Can't beat the price not to mention excellent shipping as always!

    PROS: Awesome product! Plug and play! Had minor issues figuring out how to insert the microSD but figured it out. Perhaps a simple instruction should be in the paper cover? But everything is good!

    CONS: None.

    Works as expected
    It works great on my Samsung phone but couldn't get it to work on my wife's LG phone. It also comes with a USB adapter for viewing/transferring pics to the PC.

    *I use it to view trail cam pics on the field.
