The CROSSIO SolarPower 28W consists of 4 durable panels - each providing 7W of power. Thanks to the efficiency of 21–23%, it can replace the classic mobile charger.
The folding solar panel has 2 outputs (max. 5 V / 2.4 A). This means that you can charge 2 mobiles or a mobile and a power bank at the same time, so you will also be charged.
In addition, the CROSSIO SolarPower 28W is waterproof to IPX4 (splash-proof).
