I was looking for a spare battery for my new smartphone. While searching I found this offer on Amazon. The batteries must only prove their performance, work to date, however, very good. The charger is absolute peak. I have several universal chargers that are not open far enough for very large batteries and so can only be used with clamps and rubber band. With this device, the batteries are clamped crosswise and so really fit all batteries inside. In addition, it is really very small and handy and easily anywhere portability. Of course, it takes slightly longer for the charge. This is due to the small output. Still, small, handy and can be used anywhere at an unbeatable price !!!!
