Since I am traveling a lot, I do not have only one device is needed which is compact, but also compatible with the power supply abroad (100-240V). In addition, a 12V adapter is included and you can therefore also use it in the car. Moreover, it will save you the transport of other USB chargers because the Powerline 4 Pro also has a USB charging port. So it will be loaded not only about my conventional AA and AAA batteries, but also my iPhone. Since I'm the biggest techie not necessarily, I was more than impressed by the clear and simple operation as well as the many indications in the display. It can even change the capacities of the individual batteries are displayed and you can see just what mode the charger is, therefore, loading, unloading, testing or refreshen. Also you can read on the display how far the battery is already charged or if it is defective. Have the device now for 3 months in use and am completely satisfied with the functions of the minimum size and quality, so far simply no problems. And this at a super price!
