Charge your smartphone during the match
While you play some great shots on the court, the Solar tennis rucksack generates energy with which to charge your smartphone. The 2 watt solar cell uses sunlight as a source of energy and is flexible, shock resistant and lightweight; it can also be taken out of the rucksack. Apart from that, the rucksack has a separate padded compartment for your tennis racket. Your accessories and shoes also have allocated pockets.
