I keep it on my dashboard, still works after several years!!

For how cheap this is, it's worth every penny. It charges slowly, but is very useful if you are outside all day like I am on my boat. You don't have to worry about over using your phone and depleting the battery on a sunny day.

Useless

Good little device. I keep it on my dashboard in my car to charge it. Charges fairly quickly. Take it out with me when I camp or ride my bike. Doesn't charge while in use. Won't charge a completely dead phone battery so plug it in while it's still got some juice.

Never worked
