I had originally purchased this rechargeable battery set for one of my digital cameras but we have used it for video games and controllers as well . I have to honestly say that this has been one of the smartest purchases I have made . Anyone who has a digital camera knows how they can chew threw the batteries, the Kodak Value Charger not only charges the AA batteries, but the AAA batteries as well . I have saved many times over the purchase price and am still getting usage out of it . It simply plus into a 110 volt wall plug and the indicator light flashes while charging and when completely charged it turns to a steady green light . The prongs fold down so it is easier to carry with you and you do not risk bending or breaking the prongs . This is made by the Eastman Kodak Company and as with all of their products they are high quality, high value . I recommend this charger for anyone who uses a lot of batteries .
