If you're tired of having to plug 36000 chargers for your laptops, phones or cameras, you will love this medium that allows Leitz, subject to own devices allowing charging via USB port to charge up to 4 machines simultaneously via a single power supply. The same concept frees the catch, which was nonchalantly said like that, but sometimes proves handy. The support is in the form of plastic case, housing, inside, 4 USB ports. It may be laid on the cover, the surface is anti-slip, its devices. Personally, I use 3 ports with 2 cell phones and a camera, but it is also possible to load a tablet for those who own one. The latter is easily fix into a slot provided for this purpose on the back of the base. An accessory so much practice, provided that you have multiple devices to charge, especially as there is absolutely no faults.
