I will leave this adapter permanently connected to the Tablet and use the Larger USB end for charging and connecting to the computer to prevent damage to the Micro port. This adapter is perfect for my needs. As always Monoprice has the best price and delivery!
I use my smartphone with multiple devices now. With a powered USB hub, I was able to host numerous devices sumultaneously. Obviously, not all devices communicated properly to certain software but this device does exactly what I expected it to do.
Samsung galaxy Note II SGH-i317 (t0lteatt on AOKP using Linux version 3.0.64)
Works perfect and typically use FAT32 for most of my smaller files to keep them legacy protected and forward protected. Transfers data extremely quickly at a full speed. Most phones should be able to power devices but if not you could theoretically use a powered USB to conserve battery. I have it 9/10 because it is very weak. Otherwise it seems to do its job flawlessly.
considering the price, this device is a no-brainer. it turns your android phone or tablet with a micro usb port into a mobile office, you can access usb thumb drives (if the file system is compatible - ntfs etc) on the go, use portable card readers and probably many more...
it fits well and is easy to transport (and probably easy to loose). It's an ideal companion for when you're on the road and want to access files from a usb drive with your android phone when you don't have a computer at hand. I may even buy additional ones soon and put them in all my backpacks etc.
PROS: very compact, works with various android devices
