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.

Optimized for charging efficiency Up to 85% conversion rate

State-of-the-art chipsets are not only safer, but also improve the charging conversion rate for each device. Mi Power Bank stabilizes the discharge voltage with advanced capacity sensors to optimize efficiency and durability.

  • Added100rounds
  • Increased10%power output efficiency
  • Up to85%conversion rate
