It's the one

If you fell on this charger is that your probably not simply. Do not look any further you need from Ansmann. Whether it is big and ugly but helps refresh old batteries or a charger PhotoCam more elegant and compact type, it is the only brand I know of that can charge AA battery at a time. It does not overload the batteries and detects HS batteries.
I canceled the PhotoCam to fall back on this model, which loads my flash 5 stacks at once and rejuvenate some old used batteries by my usual charger, more compact but much less "pro".
