Voltage: 5V 3.4A Power: 10W Refrigerator Host Size: Approx. 210 x 95 x 103mm / 8.3 x 3.7 x 4.1in Refrigerator Size: Approx. 175 x 60 x 25mm / 6.9 x 2.4 x 1in Storage Capacity: Able to store 3-5 insulin pens or around 10 insulin vials. 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. How to Use: To turn on or off the device, press the power button briefly. After turning on the device, pressing the two temperature adjustment buttons on the right side can adjust the temperature. The temperature can be adjusted between 0-18?, with a temperature adjustment precision of 1?. Pressing the AUTO button briefly sets the temperature to 8?. Package List: 1 x Insulin Refrigerator Host 1 x Portable Case 1 x USB Cable Notice: 1. The refrigeration box should not contain any water, to prevent liquid contact. 2. The bottom and two sides of the box should maintain ventilation holes to ensureUSB Charging Interface: Connect to an adapter, power bank, or car USB port, making it suitable for use at any location, such as home, office, car, pharmacy, hospital, or while traveling.
