A little box with its own wireless network capable of broadcasting multimedia content dune SD card (or mini SD with supplied adapter) on a tablet and / or smartphone, that it runs on Android or IOS (not tested for WindowsPhone). It allows the distribution of music, images, videos, on 4 supports simultaneously. Lappli is recovering from the manufacturer's website (demploi paper summary fashion the rest), and its use is rather intuitive - and basic.

Note that it is able to stream content WHEN IT is charging. Handy drive, with a charger-type GPS / Cigarette lighter (not supplied), to take its passengers, each with the ability to choose his distraction on the SD card (it remains to see the capacity and throughput of its SD card, for a powerful card can easily exceed the amount of single player). With a USB cable (supplied), you can use it as a simple card reader to transfer content to a computer devoid of this capacity.

Last chance (gadget?), It can serve as an extra battery for smartphone / tablet or (possibility I did not test, but I doubt its ability to take a long time).
