World-class chipset protectionNine layers of circuit protection, built by Texas Instruments
Mi Power Bank’s adopted USB smart-control and charging/discharging chips from Texas Instruments provide nine layers of circuit chip protection while enhancing efficiency.
Heat-sensitive and temperature control mechanisms ensure Li-ion batteries operate within a safe range.
The motherboard and battery are automatically protected if short circuit occurs.
Reset the power bank if it stops responding by simply pressing the Power button.
Input Over-Voltage Protection
OVP circuit prevents voltage surges from damaging the device.
Automatic Charger Protection
Detects when the charger is inserted incorrectly and will automatically stop charging.
Output Overcurrent Protection
Monitors output current and shuts off when current exceeds the maximum limit to protect the device.
Output Overvoltage Protection
Monitors output voltage and shuts off when voltage exceeds the maximum limit to protect the device.
Overcharge and Over-discharge protection
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.
Optimized charging/discharging efficiencyUp to 93% conversion rate
World-class chips built into the power bank are not only safer, but improve charging conversion rate and stabilize discharging voltage with advanced resistance-capcitance sensors to optimize efficiency and durability.
