Our Story

They said it couldnt be done

That’s what product engineers and the majority of bottle designers at Outdoor Retailer said to Cauldryn Chief designers. Boiling water from a battery was to energy intensive. Thats how the the story began, For Cauldryn the bottle itself was an obvious category while the category was massive and with a major push against single use water bottle and coffee cups. The industry as a whole had every cup, mug , bottle and design imaginable different sizes, shapes and colors however they were all fundamentally the same. The burning question was how to enter the market with a truly differential product. The seeds of Cauldryn were planted.

18 months of testing

The Concept was not only to produce a bottle that could control temperature but could do what know one else had achieved a few thought possible boil water with the bottle using a compact battery. Few gave the quest credibility with the prevailing sentiment ” that it was impossible because bioling water was too energy intensive ” It took 18 moths of testing, multiple system evaluations and more testing before the breakthrough. Cauldryn was the first, and to our knowledge the only product that can fully boil ( 212°) water with a battery.
