I received it a few days ago. It charges AAA and AA Battery´s 8 pieces in a row. You have to load a minimum of two equal batterys to load them.
When it´s charging the light turns to orange. When fully charged the light turns to green. You can put two usb charging cables in an extra usb slot to charge Tablet/Smartphone etc.
It works good. 4 AA and 4 AAA Accus are included.
I got this cheaper through a coupon, but this has no effect on my Oppinion.
