Can medicines that require refrigeration such as insulin be stored in ordinary household refrigerators? Insulin is recommended to be placed in a frequency conversion smart refrigerator. Because the temperature in ordinary household refrigerators is low (such as vegetables are often frozen), it is easy to reach or fall below 0 C in a certain period of time, and below 0 2 C Circumstances, it will cause the medicine to fail. The refrigerator door, because it is frequently opened and closed and most refrigerators are not frequency-converted, it will cause the insulin to fluctuate repeatedly up and down, especially affecting the activity of the medicine, reducing the efficacy or invalidation. ? Product specifications: Product name: portable refrigerated box Battery capacity: 13400mAh Battery standby: 8-10 hours Temperature adjustment: 2-20?, frequency conversion constant temperature, dual control of cold and heat Suitable for ambient temperature: -20-40? Refrigeration temperature: 2-8? under 7.4V voltage 26-32? environment 2-8? under 9V voltage 28-34? environment 2-8? under 12V voltage 34-40? environment Support voltage: AC 110-220V DC 7.4-12V Product size: 251 111 104mm Refrigerated size: 180 73 31mm Weight: 1.5kg ? Package: Freezer 1 Tote bag 1 Home adapter 1 12V connection line 1 13400mAh lithiumThe insulin refrigerator adopts an innovative structural design, not a design with a cable inside the flip cover, which eliminates the worries of damage to the cable. The use of high-quality circuit boards and refrigeration chips is stable and durable, and the theoretical life of semiconductors can reach 34 years!. Compared with ordinary chips, the frequency conversion chip inside the insulin refrigerator will not shut down, and the temperature is stable and does not fluctuate. The new generation 12V chip has a better cooling effect than the ordinary 5V chip and solves the shortcoming of the 5V chip that the temperature inside the box cannot drop. Power-off memory, enable without resetting, automatically resume work when incoming power, high-precision temperature sensor, real-time temperature measurement is transmitted to the LED screen to ensure the accuracy of the temperature. Three alarm modes: low battery alarm, high low-temperature alarm, so as not to affect the preservation effect of the medicine. Ensure the goodness of drugs and ensure healthy travel. The long-lasting silent cooling fan is selected, the sound is only 20db when working, and the sleep will not be affected by the huge noise. The dual-speed design reduces the speed after reaching the set temperature to make it quieter.
