The last thing you want at a music festival is your phone dying. What if you split up from your friends? What if you want to take a video or send SnapChats of your favorite songs?
Kraftzwerg is an off-grid energy storage solution that provides energy for festivalgoers, bringing the comfort and convenience of daily life into camping life. Customers are tracked via GPS and a “Kraftzwerg” battery next to their tent, which transmits a State of Charge (SOC) via LoRa Bandwidth.
