The Power Bank is capable of 2.5 recharges for the Mi 3. 2.5- full charges for the Mi 3 4.5 - full charges for the iPhone 5s 1.5 - full charges for the iPad mini * Lab test results. Actual usage may vary.World-class chipset protection. The Power Bank is built with safety, protection and efficiency in mind. Designed by Texas Instruments, the USB smart-control and power source chipsets are strengthened by nine layers of circuit chipset protection.Temperature Resistance Heat-sensitive and temperature control mechanisms ensure Li-ion batteries operate within a safe range. Protection from Short Circuit Instinctively protects of the motherboard and battery if shot circuit occurs. Reset Mechanism The power button can be used to rest the Power Bank in unstable environments. Input Overvoltage Protection An OVP circuit prevents voltage surges from damaging the Power Bank. Automatic Charger Protection Detects when the charger is inserted incorrectly and will automatically stop charging. Protection from Output Overcurrent Automatically monitors output current to protect the device and shuts off when current exceeds the maximum limit. Output Overvoltage Protection Automatically monitors output voltage to protect the device and shuts off when voltage exceeds the maximum limit. Protection from Overcharge and Over-discharge Japanese technology is used to prevent overcharging and over-discharging from damaging the Li-ion batteries. PTC Protective Circuits for the Cell Imported battery cells are equipped with PTC to effectively control and protect batteries when temperature and current exceed the maximum limit.Protective Casing.
