Feature:1. Principle: Low temperature conduction is generated by direct current on a special semiconductor to the insulin cooler case, which dissipated outward by a fan.2. LED Screen: Insulin cooler box with LED display the temperature, battery power, and fan working state, which is suitable for refrigerating various medicines.3. USB Port: Insulin cooler travel case can provide fast refrigeration, adopted USB cable connection for easy and fast charging, which can be powered by car USB port, lithium battery, etc.4. For Outdoor Use: Insulin travel cooler box is lightweight, with a handle bag for easy to carry, suitable for family, office, vehicle, pharmacy, hospital and other places.5. Prevent Bumping: Insulin refrigerated box adopted arc Angle design to avoid medicines bumping in the box, sandblasting anodic oxidation process for lasting cold temperature.Specification:Item Type: Insulin Cooler BoxMaterial: ABS, Acrylic, Electronic ComponentsBattery 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: 0-18Rated Voltage: External DC5VRated Power: 10W when connected to external power supply, 5W when connected to batteryRefrigerating Instrument Host Size: Approx. 210 x 95 x 103mm / 8.3 x 3.7 x 4.1inCold Room Size: Approx. 175 x 60 x 25mm / 6.9 x 2.4 x 1inCold Room Capacity: 3-5 insulin pens or 10 insulinPower 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 refrigerationPrinciple: 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 Mode1. Power adapter: in the absence of lithium battery or lithium battery low power, can use the power adapter.2. USB power line: can be connected to mobile USB charger, charging bank, car USB converter, using USB voltage should be 5V, 2.1A or more, otherwise it will burn.3. Lithium battery power supply:When the battery is charged, plug in the battery first, then plug in the household adapter, the wrong order, the battery can not be charged.Open the battery cover at the bottom of the host, and take the power cord and lithium electricity in the battery box of the hostThe 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 using lithium battery power supply, in order to save battery power, the machine will automatically drop any voltage, into the low voltage mo
