智能相变 暖手宝

Features & Description

1. Safety: Intelligent chip program controls heating; double-layer armored shell with flexible inner liner protection, preventing explosion or leakage; temperature control automatically cuts off power once the set temperature is reached. 2. Long-lasting constant temperature: Uses nano-microcrystalline phase-change material to store heat. It changes between solid and liquid during charging, storing five times the heat of the same volume of water, and the heat retention time is more than twice that of traditional hand warmers. 3. Attractive and portable: Ergonomically designed in a UFO shape, fits the hand better, with a more technological feel. The outer layer is coated with elastic silicone, giving a silky touch similar to baby skin. Comes with a velvet pouch for convenient carrying.
