It's a USB drive with a charging cable.
The cable, part of a just-released Indiegogo campaign, is available either in USB 2.0 or 3.0 versions and comes with a variety of storage options, from 16GB to 128GB.
The
cable comes with an app that helps you easily sync your phone's data
straight to the backup drive that's built in as part of the USB side of
the cord. The app lets you play videos straight from the drive; access
and move your photos and music; and automatically back up the photos you
post to Facebook and Instagram, as well as back up your calendar and
contacts. It also allows you to automatically sync the activity that
takes place on the drive to Dropbox and Google Drive.
That in and of itself is pretty impressive, so when you add in the fact
that the MemoriesCable can also be used to charge your iPad or iPhone
from any USB outlet and act as a sync cable between your mobile devices
and your computer, it becomes even more appealing
