Good price. It works mainly as a batter back-up. The solar charge is slow

It spoils after 6 months
Don't buy it

Works exactly as advertised. I had a power outage and a dead phone - fortunately I had charged this up to 100%, so I was able to keep my phone going until power was restored. I wish you could charge to 100% on solar, but I imagine that's a limitation of current solar technology, and not the limitation of this particular product.

did not work for any of my iPhone 4s, iPad Mini, or iPad devices. definite return

positive: Led light. small size.

negative:
Only charge 50% of the battery with solar panel.
Not charge Ipad Air.
Can not allow charge any device in the same time your are charging the devise using the solar pannel.
The interal battery is too small. Only can charge one cell phone device.
