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 a short circuit occurs.
Reset Mechanism
The power button can be used to reset the power bank in an 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
The monitors output current and shut off when the current exceeds the maximum limit to protect the device.
Output Overvoltage Protection
Monitors output voltage and shuts off when the 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 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.
- Added100rounds
- Increased 10%power output efficiency
- Up to 93%conversion rate
Aluminum CasingBeautifully textured aluminum surface
The single-piece metal casing was created by high precision CNC digital cutting. The surface is water and corrosion resistant and is perfect for everyday use.
