The Technoline BC 2500 initially strikes above all by its enormous size, which does not bother me much. At least the device looks characterized by very rugged and shock-resistant. The device just for technology-Afine user provides additional features, because you do have can display the charge status of the batteries on iPhone or Android phones. These frills, however, I do not really need, because let's face it: There is a charger and it automatically terminates the charging process to prevent overcharging, interests me as well not really. Thus, speak in any case for the charger, the own LCD display is not only available for each battery, indicating the current state of charge, but also that each discharged each battery depending on the setting, loaded / refresh ed, or on its charge state can be checked. I also think the possibility via USB interface to connect appropriate cables for loading as mobile phones, digital cameras and other devices. However, a little irritating I found the fan, which is surely disturbing depending on the location of the battery charger some. Since the device but is in my laundry room where the washing machine and other large technical devices are, not particularly bother me. But as I said to Will someone in the office, put into the living room or in the kitchen, the Lüftgeräusch is certain to hear. As an indication, since the device has a commendably quick charge, be loaded with up to 2500 mA and the device would normally overheat while the fan is necessary. If the device anyway are at a very cool place, the fan starts not only. In another review wrote another reviewer that even supposed to be 3500 mA possible, but I can not confirm, and I therefore do not want to speak again his testimony. I am at least not noticed until now. The noticed myself. For testing, I had the device in the office near the heating stand (because there was also the outlet) and the fan came on. But in the laundry room he is in an unheated room, which is very cool and dry, especially in winter, since we there often ventilate and times when I wanted to get something, the fan was not started in spite of rapid charging. Later I checked it again in the study (the unit could indeed be already broken) but since the fans came back on. Violently I also find the high price of the device, because the primary functions there are cheaper alternatives, where you sometimes but more or less have to accept slight smears. Only the display when a battery is defective, the quick charge function and the USB connection I had not in this function in my previous two battery chargers. Anyone who sees the smartphone as Anwedungen Must have and this will also be used, is certainly well served with the Techno Line 2500 BC.
