A great device. Disconnection of single drives, display, compact design. Replaces seamlessly an old 'block' and can finally my Ansmann fully recharge batteries in 2800. Schlicht recommended. USB supply I could not test.
Edit: My batteries are still only 2400. But they are loaded in record time (about 4 hours), while my old 'charging Klotz' was not able to complete charge. In addition still the thing is small enough to take it on every trip.
