The Kindle can also be properly charged using the Universal Port. Almost suspiciously quickly, because it is much faster than the PC.
Strangely, my MP3 player does not respond to the Universal Port, but only when it is connected to the working with higher amperage Smart port.
The device is a box shape on top with holder for tablets, smartphones. That is certainly quite handy better than to have the holder separately. The unit as a whole is fairly easy if the electronics are inside top quality, I can not judge. Unlike previous speakers, I am of the opinion that high-quality appearance is important when one can derive good workmanship.
Practical but would mE if the USB ports would also be the front where the holder is, and not behind the power cord. Then the device could operate from the front that is also easy.
Annoying and misleading, though, is that Amazon displays the wrong product image, namely the high-order device with six ports and pilot lights, which has led me to purchase. The description of the product then again refers to the actual product, it does not get any better, but still dubious, because the picture so significantly characterizes my idea from the device.
It has already bothered me in the past massive that Amazon apparently simple agglomerate the reviews on all different devices and so deceiving customers.
