This Flat Bottle Becomes a Kettle When You Need It Most - Yanko Design

"At first glance, Tetra looks like a streamlined water bottle dressed in a minimalist gray shell with sunny yellow corner accents. It's flat, roughly the size of an A5 notebook, which immediately tells you someone thought hard about how this would actually fit in a backpack. But here's where it gets interesting: that yellow base section? It's not just decorative. It's a detachable heating deck that transforms your water bottle into a portable kettle when you need it."

"The modular approach is what sets Tetra apart from the crowded field of travel bottles trying to be all things at once. Instead of permanently integrating heating elements that add weight and complexity to something you might carry daily, Amal SS separated the functions. Need just a water bottle for your commute or gym session? Leave the Thermo-Deck at home and travel light. Heading into the wilderness for a camping trip? Snap it on and you've got hot water capability wherever you land."

"This kind of thinking feels refreshingly practical in a world where most products seem designed to cram in every possible feature whether you need them or not. The architecture here respects how people actually use things. Your daily hydration needs don't require heating functionality, so why carry that extra weight around? But when you're watching the sunrise from a mountaintop or setting up camp after a long hike, having the ability to heat water for coffee or tea without packing separate equipment becomes genuinely valuable."

Tetra is a flat, A5-sized travel bottle with a minimalist gray shell and sunny yellow corner accents. The yellow base is a detachable Thermo-Deck that converts the bottle into a portable kettle. The modular design separates daily hydration from heating capability so users can travel light without permanently added weight. The Thermo-Deck snaps on for camping or outdoor use to provide hot water for coffee or tea. The product emphasizes durability, thoughtful interaction, and practicality, prioritizing real-world use patterns over cramming unnecessary features into everyday carry items. Corner guards and flat profile improve packability and protection during travel.
