I purchased my Kodak Ni-MH Rapid Battery Charger specifically for my camera.It can only be used for that specific camera, so it is not interchangeable like some other chargers. You can only charge the one size, and one set at a time.The light indicator flashes orange as it is charging and turns to solid green when completely charged. I have definitely saved countless money with purchasing this charger but do keep in mind it can only be used for the one battery set. Another feature I did not care for was the prongs on this one, it does have a push latch where it can be used over seas, but when it comes off it is difficult to get back on for the American outlets. Also the prongs do not fold in so it makes it a bit more difficult to carry with you. This is another product by Eastman Kodak Company and over all it is a great product as far as reliability and strength but I think the design was not well thought out.
