Feature: 1. Product Principle: This product uses semiconductor temperature difference cooling components to achieve refrigeration. Direct current generates low temperature on special semiconductors, conducts it into the medicine box, and dissipates heat outside through the radiator and fan. 2. Portable: The overall size of the cooler box is small and lightweight, and it comes with a customized carrying bag, which is convenient to carry outside, and at the same time prevents the instrument from being scratched and broken, so as to better protect the instrument. At the same time, the cooler comes with its own carrying handle, which is more convenient. 3. Touch Digital Keys: Insulin refrigerator says goodbye to the traditional mechanical keys and uses the new touch digital keys, which are easier and simpler to press and the digital screen is more intuitive to watch, so it is easy to use for the elderly. 4. Adjustable: Insulin refrigerator box is adjustable from 018, LED display can observe the temperature, battery power and fan working status in real time, suitable for refrigerating various medicines, fast cooling and accurate temperature. 5. Special design: Aluminum inner liner with rounded corners to avoid drugs bumping inside the box, sandblasted anodic oxidation process to make the cold storage temperature lasting. Increased capacity design of the inner liner can hold more medicines, suitable for long time use outside. 6. Alarm Reminder System: With more intimate alarm reminder system, when the machine is low on power, the reefer box will beep intermittently to remind the user to replace the battery, charging and so on. 7. Wide Application: The insulin refrigerator is not restricted by the place, it can be used in any place such as traveling, home, office, vehicle, pharmacy, hospital and so on, providing convenient medication service for diabetic people. Specification: Item Type: Insulin Cooler BoxMaterial: ABS Built in Battery: 10600mAH lithium ion battery Temperature Control Range: 0-18 Main Unit Rated Voltage: DC5V Main Unit Rated Power: 10W when connected to external power supply, 5W when connected to battery Refrigeration Room Capacity: 8 insulin pens or 28 bottles of insulin medicine, or 62 insulin pen cores Power Supply: USB cable connection to adapter, power bank, car USB port, lithium battery, etc. Applicable Places: Travel, home, office, vehicle, pharmacy, hospital, etc. Suitable for Refrigeration: Insulin, interferon, and other drugs and biological agents that require refrigeration Product Principle: This product uses semiconductor temperature difference cooling components to achieve refrigeration. Direct current generates low temperature on special semiconductors, conducts it into the medicine box, and dissipates heat outside through the radiator and fan.
