Pre - I review here the Lumsing charger for directly into the wall socket, without cable and 4 USB ports. Some of the other reviews here seem to refer to the 5-port device. The unit confused the feel a little .... Even if it looks in the photos on plastic and also minimal after smells, so it feels rather like irgenetwas between Cork and flowerpot on. Anyway, very difficult to describe and definitely if you then rummages with recognition in a travel bag ;-) The instructions are in English and "German", but you can enter into the ton. The German Horrible, but you can see what will be said. In principle, however, is nothing else of relevance, which in any case is not already clear. Here are two quotes: "4. Built heatsink, 4.2A maximum output can charge your devices quickly with low amount of heat." In German: The device is probably not too warm / hot. Interestingly this point: "5. A total of 4 LED indicators. The USB port is marked with the charge device model, the devices that are used in the corresponding device interface can charge with maximum efficiency." While it indeed is a designation with "iPhone, Android, iPad, iPad" there are all around the unit but no LED's! Needed are not anyway, but if they are mentioned of course you look for it. Also bothers me here is that the type of use is not the output voltage. (Not every Android device needs eg 1.2A) I use namely no iPhone and no ipad and so can only guess whether the adequate current for my Tablet / Smartphone / Power Bank or whatever is. Of course you can combine, but do I always find expect the stupidest anticipated user and could, at least to write as much amps are supplied.
I'd love to give 5 stars, but are the minuses - Poor instructions - Small Beschiuchtungsabplatzer the housing (not very relevant) - Inadequate labeling of the respective ports too much for me to put it in the category of "I like it very" stuck to. Even the included microUSB cable would be a great thing, it is but with a "please use original cable" in the instructions already discarded ...
