Not very good. You could probably get something cheaper that works better than this!,

This review is from: Solar and Dynamo Powered LED Torch - Flashlight and Emergency Mobile Phone USB Charger - Black (Sports)
Super quick delivery, and torch very impressive, however as a charger it takes 5 minutes of winding to get 1% charge, the solar panel doesnt work at all! However in an emergency it would be helpful, that is if it works!!!!
