This is a camera battery charger. To accommodate the bewildering plethora of different sizes, the manufacturers have come up with a neat trick. The main body of the charger is just a housing for a custom-shaped insert, which clips into the housing and holds the battery. This means that when you receive this item, it'll be in several boxes containing the main unit in one pack, and the custom holder in another. This isn't a flaw, this is nifty and innovative design at work since only the simple-to-make holder need be churned out in a myriad of forms; the main body can remain the same, simplifying the production line immensely. That's why this item is so cheap; it ain't shoddy, it is very, very well designed.
