Product Functionality

The utilities of Birksun solar backpack are many. We can maximize them when we understand it properly. Birksun serves us more than a normal backpack with its added feature.It’s important to understand how that additional feature of the backpack works.

Birksun backpacks charge our gadgets with a speed equal to that of our traditional wall chargers. When exposed for 2 min to the sun, a Birksun backpack can deliver power equivalent to 1% of mobile battery. In almost 3 hours, Birksun with its lithium built-in battery of capacity 3000 MAH can charge your device. It also supports simultaneous charging. Birksun backpacks deliver power while being powered by the sun or from an external power source.

When you want to charge up your mobile, you don’t have to support it by holding it in your hands and adjusting its connection with the bag.Birksun backpacks address this pain with its stylish design. It has a dedicated space for both built-in power delivering battery and for your gadget.
Connect the mobile to the battery with a USB provided by Birksun and immerse yourself in any activity. It remains safe and intact with the bag unless you disconnect it when you need.


Birksun solar backpacks have highly durable and strong scratch-proof solar panels. They efficiently collect the magical energy of the sun and preserve it for us for a longer time than expected. Birksun solar panels belong to the latest generation of Nano-crystalline technology.

They have a higher absorption capacity. With thinner films, integrated along with fabric they beautifully hide into the texture of the bag. They add a greater flexibility without being sturdy and tough, not compromising on the smoothness of the bag.

Birksun takes a great care in giving an elegant and unique shape to every product. We quickly fall in love with the feel of these backpacks. Birksun’s finest fabric gives a comforting touch when it’s on our back. Standard YKK zipping shields everything inside from outside.
