Users Need Multi-Temperature Vacuum Flasks for Autumn and Winter

Users want two vacuum flasks preset to different temperatures (e.g., 55°C and 90°C) in autumn and winter. Existing kettles cannot maintain temperature for a long time causing high power consumption. The market lacks large-capacity vacuum flasks with electric heating functions to meet this need.

Who would pay

Consumers using hot drinks during autumn and winter and dining establishments willing to pay for energy-saving and convenient thermal insulation devices.

Current workarounds

Currently, people combine kettles and vacuum cups, but kettles do not keep water warm and consume much power for long-term constant temperature maintenance. Users need a more power-saving and convenient solution for accessibility.

MVP idea

Develop a detachable large-capacity vacuum flask that can set multiple preset temperatures, with both insulation and electric heating functionality, ensuring energy saving and portability.

How to validate

Test the demand for multi-temperature vacuum flasks via online market research first. The risk is that high technical difficulty may lead to excessive costs.
