Quick post: Do not buy this item. It's a portable battery charger for your cell phone. I left my phone charger at work this weekend, so on Saturday I decided to buy this little portable guy. He does not work. And I was without a phone Sunday due to him. I do not like him, and as I soon as I remember where I put him, he is going back where he came from.
The end. And yes, I followed the directions.
