I find this very powerful charger as the charging time is about 4 hours fast.
It is very light with its sleek design. It allows simultaneous charging of batteries of different sizes, AA and AAA. Only flat, it is not compatible with 9V batteries.
Moreover, an indicator light from green to red indicating the end of battery power. This will make energy saving avoiding leaving the charger plugged unnecessarily. The indicator flashes red to indicate a charging problem or incorrectly positioned batteries.
This charger can be used in all he fact that safety is certified by renowned lorganisme of security: DEKRA.
Rechargeable batteries are as powerful as disposable batteries (even more because they take longer to load) but which are more economical and which limit the waste.
I regularly uses for Wii controllers and Wii Balance Board, my camera, my epilator, my mouse and keyboard dordinateur.
