★★☆☆☆
Takes a long time to charge with solar and can only charge two times when fully charged.
I choose this one amongst the others because of the review rating. It came with a 75% charge - 3 blue LED, and it drained down to one blue LED after charging my iPhone to 80%. The math doesn't seem to add up according to the device rating. Then I charged the power bank in the sun for about 15 hours and it still showed one blue LED. So I begin to read the review comments in Amazon that perhaps I did something wrong or I forgot to remove a cover on the solar panel. After reading several 5-star comments, they are all talking about some calendar, and I thought I was looking up the wrong order. I should've listened to my intuition to buy one with multiple solar panels and a more reasonable rating. Another thing I learn is to read the 2 to 4-star comments because they are more relevant.
