Wattsun

Wattsun pop-up power was officially founded in 2016 by current owners Koen Olieslagers and Bart Hendriks. Olieslagers came up with the first concept a year before while working as an industrial product designer. Hendriks soon followed after finishing his bachelor commercial economy in the summer of 2016. The two had met while studying at the University of Applied sciences Arnhem Nijmegen (HAN) and decided to pick up Olieslager’s idea. In 2016 the first sketches of the Wattsun-concept were drawn onto paper, the very first within the field of stackable battery systems. On these sketches Olieslagers took stackability, portability and ease of use into account. Simultaneously they conducted research into the perfect battery to fit this system. The perfect fit needed a suitable energy density, proper cycle, had to be light weight and trustworthy. The results formed the foundation of the unique stackable battery system that we now know as the Wattsun.
