Power Supply: USB cable, adapters, power banks, and car USB ports. Suitable for Use: Traveling, home, office, car, pharmacy, hospital. Suitable for Refrigerating: Ideal for refrigerating drugs and biologics requiring refrigeration, including insulin and interferon. Product Principle: This product uses a thermoelectric cooling component or semiconductor to achieve refrigeration. By applying a DC electric current to an area of the semiconductor, low temperatures are generated, and then these low temperatures are conducted to the medicine box. Finally, heat is dissipated outward by the heat sink through a fan. Product Characteristics: Includes intelligent temperature control, a LED liquid crystal display screen, and instant semiconductor cooling technology. The product is stable, long lasting, low noise, and zero pollution with fluorine. Additionally, its small size and lightweight body make it easy to carry.
