The Symlis Sparrow is a portable flash drive and charger that not only charges your electronic devices via USB but also has a flash drive attached which you can use to store your files.
The Sparrow is effectively a short USB cable with magnets on either end. The magnets allow the ends to snap together, creating a loop that can be placed on a key chain for easy portability. This design keeps the device compact but also gives users enough slack to work with when it's opened up -- more so than most USB cables.
With its charging capabilities and the added convenience of storage space, the Symlis Sparrow flash drive and charger device represents a handy alternative to charger cables which are annoying to carry around.
