By capturing more sunlight than its contemporaries, the ECEEN solar backpack is capable of generating more electricity per panel. The power drawn goes into the large-capacity 10,000mAh emergency power bank which is waterproof and works as a handy backup battery pack when you’re outdoors for a camping adventure. All the solar energy that gets absorbed by the solar panel is safely stored to be used for emergency battery backup later. Even if your devices run out of power at night, this charger can still power them back. You just have to hang the solar panel charger on the back of the backpack so that it is able to draw energy from the sun during the day. The process of attaching them to the backpack is made easy with the help of the convenient clips. Ultra light and portable solar charger backpack designed for the modern tech-savvy generation.
