Mini MicroSD Card Reader for Android

Really small. Truly portable. Actually useful. Specially engineered for your Android smartphones & tablets.

Like an SD/MicroSD card reader that you often use on PC computers, except this one comes with a MicroUSB connector to plug into smartphones & tablets with MicroUSB port. Use it to play video/music on a MicroSD card. View photos/documents, copy and backup any and all of your files. Just like what you can do on a PC.

Attach this coin-size card reader to your keyring and take it anywhere you go. Never run out of storage space again.

Works with Nexus 5 (third-party software required or device being rooted).


"..., this is arguably the easiest and most elegant way to add a microSD slot (or even a second one in the case of something like the Galaxy S4). And for 12 bucks, how can you go wrong?"

-- Rick Broida, October 15, 2013; CNET Reviews: Android Atlas
"So far in my experience, I have nothing but good things to say about the tiny accessory. I found that it’s small stature was way more convenient to use than the traditional micro SD card reader/USB OTG cable combo and at $12 ($3 worldwide shipping), it wont break the bank."
