"Revolver" is helping to charge the battery from used batteries.
After using a battery in MP3, CDP, Digital Camera, and Toys, thebattery has a small balance. In this way, we dump a lot of the small balance battery. In other words, we dump our resources. It can be recycled. That's why we invent this product for saving our resources even if it is very small. Also this product shape is like as a revolver, so it has a lot of efficiency.
