The charger is not only stable and - as you might expect from Ansmann - high-quality workmanship, but also fulfills its purpose as simple as well. Finally I have a charger for the increasingly frequent AAA cells found - conveniently also the same for AA and 9V batteries. Each charging socket loads separately, ie you can at different times on or reloading individual cells. Reference to the accompanying short explanation can be found in seconds out how long that cell needs to be charged - the non-existent state of charge light therefore do not miss it.
