For years, I use only battery chargers from company Ansmann as they take not only in the test reports of many journals always as the winner or in the top position their place, but also in daily use their performance skills. For this battery charger I have decided, as it separates from the mains after charging. I like the design because it is wertig different from many other devices. I've had good experiences with the Ansmann battery chargers only, so I understand many reviewers do not, do not write a critique for its own sake.
