This charger is a complete waste of money! It has the shortest life between charges. In less than a month it stopped working. I would not recommend this to anyone. They could have at least made one in two different sizes. I had to give 1 star, otherwise I wouldn't even write this. Stay away from anything from PowerGen! You WILL just be tossing your money away. Never again! Don't buy it... Go and get a name brand instead. Save yourself a headache!!!
