Specification: Item Type: Insulin Cooler Material: ABS, Electronic Components Temperature Setting Range: 0-18? Voltage: 5V 3.4A Power: 10 W Refrigerator host size: approx. 210 x 95 x 103 mm / 8.3 x 3.7 x 4.1 inch Refrigerator size: approx. 175 x 60 x 25 mm / 6, 9 x 2.4 x 1 inch Storage capacity: Can store 3-5 insulin pens or about 10 insulin bottles. Power supply: USB cables, adapters, power banks and car USB ports. Suitable for Cooling: Ideal for cooling drugs and biologics that require refrigeration, including insulin and interferon. Product principle: This product uses a thermoelectric cooling component or a semiconductor to achieve cooling. By applying a direct electrical current to an area of the semiconductor, low temperatures are generated which are then transmitted to the medication box. Finally, the heat is dissipated from the heatsink to the outside via a fan. Package List: 1 x Insulin Fridge Host 1 x Portable Case 1 x USB Cable Note: 1. The cool box should not contain water to prevent contact with liquids. 2. There should be ventilation holes on the bottom and both sides of the box to ensure air circulation. When stowed in a portable backpack, the ventilation openings must exactly match those of the backpack. It is strictly forbidden to put this product in a sealed bag, which will cause poor ventilation and internal temperature rise, which may cause damage to the drug. 3. When you travel, please prepare appropriate power supply methods according to the travel time to ensure the product can work properly.Adjustable Temperature: Easily adjust the temperature from 0-18? through the LED display, very suitable for cold storage of various medicines with fast cooling and precise temperature control. The power and temperature indicators are accurate and easy to understand, which makes the operation more convenient for the elderly. USB charging port: Plug it into an adapter, power bank or USB port in the car, so it can be used anywhere, e.g. B. at home, in the office, in the car, in the pharmacy, in the hospital or when travelling. Anti-collision: The arc angle design of the inner tank prevents the drug from colliding in the box while driving. The sandblasted anodizing technology ensures long-lasting temperatures. Fast Cooling: The cooler adopts semiconductor instant cooling technology, which has stable performance, low noise and no fluorine pollution. The radiator is cooled by a fan to achieve heat dissipation. It's quieter and more durable than ever, ensuring a restful, restful night's sleep.
