World-class circuit chip protection.Nine layers of protection, built by Texas Instruments

Adopted USB smart-control chips and charging/discharging chips from Texas Instruments.
Mi Power Bank not only provides nine layers of circuit chip protection, but also enhances efficiency.

Temperature Resistance: Heat-sensitive and temperature control mechanism ensures Li-ion batteries operate within a safe range.
Protection from Short Circuit: Automatic protection to the motherboard and battery when short circuit occurs.
Reset Mechanism: Power button can be used to reset the power bank in unstable environment.
Input Overvoltage Protection: OVP circuit prevents voltage surges from damaging the device.
Protection from Incorrect Insertion: Detect when the charger is inserted incorrectly and automatically stop charging.
Protection from Output Overcurrent: 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.
Protection from Overcharge and Over-discharge: Japanese technology is adopted 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 current and provide protection when temperature and current exceed the maximum limit.

Optimized charging/discharging efficiency up to 93% conversion rate

World-class chips are not only safer, but improve charging conversion rate and stabilize discharging voltage with advanced resistance-capacitance sensors to optimize efficiency and durability.

Aluminum Casing Beautifully textured aluminum surface
