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.

• Temperature Resistance

  Heat-sensitive and temperature control mechanisms ensure Li-ion batteries operate within a safe range.

• Short-circuit protection

  The motherboard and battery are automatically protected if short circuit occurs.

• Reset Mechanism

  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.
