This can be useful if you want to build a homemade phone charger, cuz amazingly it's quite efficient. The recharging circuit is on the right. This is pretty basic so I don't suggest you charging your phone per se, maybe charge speakers of any other devices. 
The specs are:
- Input Power - 6.4W
- Output Power - 5W
- Efficiency - 78%
