Insulin Cooler Case LED Screen Intelligent Temperature Control Insulin Cooler Travel Box with 10600mAh Battery Item Type: Insulin Cooler Box Material: ABS, Acrylic, Electronic Components Battery Type: Lithium Battery NCR18650B 10600mAh 5V(Included) Battery Life: About 4-10 hours (the higher the temperature, the shorter the service time) Temperature Adjustment Range: 0-18℃ Rated Power: 10W when connected to external power supply, 5W when connected to battery Refrigerating Instrument Host Size: Approx. 210 x 95 x 103mm / 8.3 x 3.7 x 4.1in Cold Room Size: Approx. 175 x 60 x 25mm / 6.9 x 2.4 x 1in Cold Room Capacity: 3-5 insulin pens or 10 insulin Power Supply: USB cable adapter, charging bank, car USB interface, lithium battery, etc. Applicable Place: Travel, home, office, vehicle, pharmacy, hospital and other places. Suitable Refrigeration: Insulin, interferon and other medicines that need refrigeration Principle: Uses thermoelectric refrigeration components, namely semiconductors to achieve refrigeration, in a special semiconductor through direct current generated low temperature conduction to the box, and dissipated outward through the fan. Function: A variety of power supply, AC power supply, USB power supply, built in battery, charging bank, intelligent temperature control, large screen LED temperature display and other functions, semiconductor refrigeration technology, stable performance, long life, no noise and no fluorine pollution, small size, light weight, easy to carry, is a new type of green products. Use Method: 1. Power on: (1) External power supply: when there is no built in lithium battery in the host, switch on the power adapter or USB power supply, the machine will beep a "di", indicating that it has been powered on, and the machine automatically detects whether the battery is installed, if there is no battery, the screen displays the full battery. (2) Battery power supply: when the external power supply is not connected and the built in lithium battery is directly connected, the machine will beep a sound, indicating that the battery has been connected, and the screen will not display. (3) Internal and external power supply at the same time: when the battery has been connected to the case, when connected to the external power supply, the screen will display the power indicator, and detect the power, such as the battery is fully charged, the battery display full, such as the battery is not full, display the corresponding power and charge at the same time. Switch: 1. Startup: press the "power button" for 1 second after startup. After a beep, the screen lights up. The temperature displays the current temperature in the box, as well as the battery power and fan working state. 2. Shutdown: long press the "power button" for 3 seconds to shut down, shut down, such as the machine has a battery, the screen only shows the power mark. 3. setting temperature: refrigerator box temperature setting range 0-18℃, directly press the "▲" "▼ "key, temperature flicker, at this time you can set the required refrigeration temperature. Power Supply Mode 1. Power adapter: in the absence of lithium battery or lithium battery low power, can use the power adapter. 3. Lithium battery power supply: Open the battery cover at the bottom of the host, and take the power cord and lithium electricity in the battery box of the host The power line card of the pool is connected, and the battery is put into the box and covered. In the case of sufficient lithium battery power, the lithium battery can be directly used for power supply. Internal lithium battery power supply for about 4-10 hours, depending on the ambient temperature, the higher the ambient temperature, the shorter the service time, you are advised to choose more lithium batteries. When the external power supply and the built in battery are connected at the same time, the refrigerator shall preferously use the external power supply for refrigeration and charge the built in lithium battery at the same time. Battery Charging Mode: 1. Boot charging: After the built in lithium battery is connected, connect the power adapter or the car power cord to the host, and the machine display will show the charging state. At this time, the charger will supply power to the machine and charge the battery at the same time, which will take a long time, about 3-5 hours. 2. Turn off charging: when the machine is in the shutdown state, the power adapter or car power cord access to the host, at this time the host default automatic charging, the screen displays the corresponding power and charging state, charging under the shutdown state can effectively save the charging time, about 2-3 hours. Fault Analysis 1. The machine does not refrigerate: the refrigeration chip interface may be loose or damaged refrigeration chip. 2. the display temperature is more than 30 degrees: check whether the fan is working, whether the ventilation hole is blocked. 3. The temperature i
