In case you haven’t noticed, you can’t connect your regular USB stick to your tablet or smartphone without an adapter. Sony’s latest 2-in-1 USB flash drive is different. It has micro USB and USB 2.0 connectors, so you can connect it to your Android tablet or smartphone easily. It offers OTG function, so you can use it to store your photos and other files. The flash drive has a locking cap. The 8 GB version costs $20.
