I will not dwell on the specifications of this product. I think it is relatively big and noisy. From using a charging current of about 1000 mA, the fan will be turned on a regular basis, and makes itself actually quite noticeable.
Plus points are, of course, the gentle treatment with deltaU battery shutdown, various discharge and refresh modes, the illuminated display and of course the connection of a smartphone app via Bluetooth. This turns out in practice to be quite useful - if you are technically interested and curious, really necessary is not. The unit can also be operated via the buttons just fine.
Is there equipment worth the money? I would say yes, if, yes if the unspeakably rasping fan would not. Which reduces the otherwise high-quality, professional impression of the charger colossal! Otherwise, you get a comfortable, fast charger with an informative smartphone connectivity as USP.
