BigBlue 5V 28W Foldable Outdoor Solar Powered Charger With SunPower Solar Panels 3 USB Ports I often am out backpacking and hiking during the summer months. I carry rechargeable batteries, but find myself using them up before I return. I found this solar panel and wanted to try it for recharging my devices while out on the trail.   Pros:    • 4 panels • 3 USB Ports • Loops for Caribiners • 4 Caribiners included • Short Micro USB Cable included • Charges even in low sunlight • Does not drain battery when out of sunlight    Cons:  None This solar charger is very well made. All the stitching is tight. The velcro sticks very well. The panels are water resistant and scratch resistant. It folds up very compact. The overall weight is not very much compared to a large battery. The USB ports are easily accessible. There are three of them. The pouch is very convenient to store a phone or battery in while charging. Three devices can be charged at one time. When using a solar panel, I will often charge my batteries, then charge my phone. The power output on a partially sunny day was very impressive. Nearly 5 volts. As the sun came out more, it pegged the 5v mark. Amps increased as well. The meter I used to measure Voltage and amps was not very readable in the sunlight. But it was measuring very good voltage and amps. Overall, I am very pleased with this solar panel.
