Flash drives — so useful. Almost everyone I know has a small collection. What would make them even more useful would be if they could be plugged into your phone as well.
And the good news is: they can! A growing number of Android devices have USB OTG (USB On The Go), which allows connection of USB devices. Only one problem remains: Android devices have micro USB connectors & flash drives have full size USB — except a few have both:
Leef Bridge
SanDisk Ultra Dual
If you want to use your existing USB flash drive with your mobile device that has USB OTG, try a USB-to-micro USB adapter.
iStick
If you have an Apple i-device with Lightning connector, there's something for you too:
