Medical-grade precise temperature control, taking care of drug activity Fixed refrigeration zone: Adopting advanced semiconductor refrigeration technology, it can accurately maintain a low-temperature storage space of 2 - 8 under the ambient temperature of 25, which is strictly in line with the optimal refrigeration requirements of insulin, interferon, growth hormone and other medicines, effectively preventing the medicines from failing and deteriorating due to the high temperature, and retaining the activity of the medicines and the therapeutic effect to the maximum extent. Intelligent Temperature Adjustment: Equipped with high sensitivity temperature sensor and intelligent temperature control chip, it can monitor the internal temperature in real time and adjust the cooling power automatically to ensure the temperature fluctuation is controlled within a very small range. Convenient multi-scenario power supply, worry-free battery life USB universal interface: support a variety of USB power supply, whether it is connected to the home power adapter (90V - 240V universal, compatible with 110V and 220V voltage), car USB interface, or external rechargeable treasure, you can power the refrigerator at any time, anywhere, to meet the needs of different scenes such as home, office, travelling, long-distance travel, and so on, to completely get rid of the power limitations. Portable and lightweight design, zero burden on travelling Compact body: the overall size has been carefully designed, compact and lightweight, easy to carry. Equipped with ergonomic comfortable handle, whether hand-held, shoulder or into a bag, will not occupy too much space, daily commuting, business trips, outdoor travel can be easy to travel, at any time for the medicine to provide the appropriate low-temperature environment. Sturdy protection: The outer shell is made of high-strength, wear-resistant and environmentally friendly materials, with excellent impact and scratch resistance, effectively resisting the collision and friction in daily use. The internal aluminium alloy liner with curved corner design not only prevents the drugs from colliding with each other in the process of moving, but also enhances the heat preservation and refrigeration effect through the unique sandblasting anodic oxidation process, and maintains the internal low-temperature environment for a long time.
