I have a digital camera that uses two AA batteries. And if you know anything about digital camera's you know how fast they eat up conventional batteries. With the hundreds of pictures I'm required to take each week on my job, I would be buying batteries for my camera like crazy and spending a lot of cash in the process. I bought the Duracell 15-minute charger to save on the cost of batteries. The charger comes with 4 AA batteries and can also charge AAA batteries. You can use any brand rechargeable battery in the charger, not just Duracell. I used the batteries that came with the charger for several months before they failed to work properly and I had to buy more.
The charger is easy to use, just insert the batteries and plug in any outlet. It's compact enough to take along when you travel. There is a red indicator light that glows while charging and goes out when it's done charging.
I really like this charger and how quickly I can have fresh batteries to use in my camera or any other device. It's especially useful to have the ability to charge up to four batteries at a time, so I have two to use and two as a backup before I need to charge them up again.
