Amazon is offering the ECO-WORTHY 100W Portable Solar Panel for $84.99, after clipping the on-page 15% off coupon. With the coupon dropping the price from $100, this discount matches previous markdowns we have tracked to remain as the all-time low. With an easy to move size of 26.2-inches by 21-inches by 2.8-inches, this 100W solar panel weighs a measly 7.7 pounds and is able to fold up to save you storage space. Built with an IP65 water-resistant material, it is compatible with most power stations and solar generators thanks to its four adapters – and can even be connected alongside other solar panels to increase charging power when this one alone isn’t enough.
