Portable Foldable Kettle A portable foldable kettle is a drinking tool designed specifically for travel. Its core advantages lie in being "foldable + lightweight" — when folded, its volume is only about 1/3 of that when unfolded. It can be easily stored in a backpack or handbag, making it suitable for scenarios such as business trips, camping, and hiking. In terms of material, most are made of food-grade silicone or PP, with a wide temperature resistance range (usually -20℃ to 200℃). They can hold boiling water directly and be heated in a microwave; some are dishwasher-safe, ensuring safety and easy cleaning. In terms of functions, most are equipped with sealed leak-proof lids to prevent spills when inverted; some models have built-in filters for making tea or brewing coffee conveniently; others add a temperature display to avoid scalding. It solves the problems of traditional kettles taking up too much space and disposable water cups being non-environmentally friendly, making it a practical item for modern travel.
