4.3 Selling Point vs. Decision Driver Alignment

4.3.1 Alignment Analysis

The category's mainstream selling points (portability, fast heating, precise temperature control, long battery life, safe materials) closely align with users' core decision factors, indicating sellers largely address the most urgent needs. However, significant execution gaps exist: 1. 'Fast Heating' Perception Gap: Despite widespread 'fast heating' claims, user reviews (particularly for refrigerated milk or sleeve-type products) frequently complain about slower-than-expected heating times, creating unmet expectations. 2. 'Leak-proof' and 'Easy Cleaning' Misalignment: Sellers emphasize leak-proof designs and easy cleaning, yet leakage issues (especially in adapter-dependent products) persist in user feedback. Complex structures also make cleaning a major pain point, undermining trust in product reliability and hygiene. 3. 'Long Battery Life' Performance Decline: Promised battery longevity is contradicted by widespread reports of rapid degradation or charging failures, eroding the core value proposition of portability.

4.3.2 Key Findings

• Consumer expectations for 'extremely fast and uniform heating' significantly exceed current market standards. Products achieving genuine rapid uniform heating would gain strong competitiveness; conversely, exaggerated claims cause negative reviews and trust erosion.
• Performance in leak-proofing and cleaning directly influences user trust in safety and hygiene, the core foundation. Leaks and cleaning challenges not only cause inconvenience but also pose health risks, severely damaging brand reputation and loyalty.
• Battery longevity and charging reliability are critical to the long-term value of portable products, not just initial capacity. Rapid battery degradation or charging issues nullify portability benefits, driving users back to traditional methods and causing product abandonment.
• The market is evolving toward 'multifunctional integration' and 'premium materials', with latent user demand for 'all-in-one' solutions. Products offering sanitization, large capacity, 316L stainless steel, etc., can better meet deep-seated health and convenience needs, command higher prices, and attract broader user segments.
