Does the subject want to ask "the reason why the little white bear thermos can't burn below 100 degrees"? The reasons are as follows.

1. The power of the little white bear constant temperature kettle is not high enough to heat the water to 100 degrees.

2. The temperature of the kettle cannot reach 100 degrees due to the failure or damage of the kettle. You can contact after-sales service for repair or replacement.

3. The low temperature of the environment will affect the heating effect of the kettle. You can try using the kettle in a warm environment.
