Review on 🌞 Efficient 80W Portable Solar Panels: BigBlue Foldable Solar Charger for Fast Charging - Perfect for Camping, Generators, Tablets, Cellphones, and More! by Tiarik Gonzalez

I used this to try and charge my CPAP backup battery pack Renogy 72000mah 266wh 12v power bank I just bought. Why is it so important? Most of these foldable panels are the same size and supply 18 volts, which is great for the vast majority of solar panels. This beautiful panel delivers 12 to 18 volts and up to 4.45 amps. This is ideal for the Renogy that requires an input voltage of 15V and 2A. These standards are hard to come by. By the looks of it, the controller on this Big Blue 80W panel is smart enough to do just that! He immediately started charging the Renogy. Thanks to such a great panel I will be keeping a CPAP backup.
