DESIGN: There are no flashing or bright lights or similar operation off - ie there is no disturbing light in the room. Since I've installed it in the closet, in my light cable turn. Relatively small device and elegant design! Looks pretty cool, my charge Unit :)
CABLE: is advisable to use rather short USB cable or to select them, otherwise there will quickly clutter. Ideally, you put it in a cable box and placed the device on top of it, so everything stays neat and handy. The supplied cable is white and even has a Velcro strip off, that's smart.
CURRENT: I'm testing just how different device behavior at the various loading ports. So far, everything fits. Allegedly, USB devices regulate (mobile, etc.) always needed your power itself down, ie, smaller units may the powerful 2.4A charging ports.
Bin It further test out - but so far a very good recommendation if you have to load multiple USB devices such as bike lights, smartphones, iPods, etc.
Hope my feedback will help you further.
