The idea is to take batterypack where there is no electricity available. With the help from solar panel one can charge the battery on the go. In addition, when hiking at winter time battery can be charged at home. So no need to wait until sun starts to shine ;D.
I really look forward to see more from Tespack!
Perfect bag when bicycling or hiking!
Batterypack is seated inside the bag.
It also has a 2 A plug for quick charging!
