Volt Volt provides power for your smartphone during festivals and events. Their service is based on high quality, realiable power banks which can be exchanged very quickly during the festival as often as needed. No wating in line, just power. Formika helped Volt with an ergonomic and durable redesign, and sourcing of the power banks inner components. The new batch of power banks was introduced on Roskilde Festival 2019 and provided festival goers with a stable source of power for their phones.
