The charging station is working properly, and the battery with 2700mA are for my digital camera, if you want to spend no more than 50 images with flash, very appropriate. Represents more pictures yes then the second battery pack available. When the batteries are completely empty, the charging time is about 10 hours. And who the manual also read through, then even as the batteries are inserted in the white charger. I am very pleased with this product in any case.
