Review on High-efficiency 100W Portable Solar Panel, Sunpower Cell Foldable Solar Charger with USB Outputs 🌞 – Ideal for Charging Laptops, iPhones, Solar Generators Power Stations. Perfect for Outdoor Camping, Travel. by Craig Walters

You get what you pay for. I have both this and the Jackery Solar Saga 100 and at the same time in the same sun this panel puts out only 13 watts while the Jackery gives me 35 watts. So you get what you pay for. It doesn't give you the same amount of power and just doesn't seem very efficient compared to Jackery solar panels.
