The safe, high-quality circuit chip
Using highly accurate sensors, this advanced chip is not just safe, it also has a higher conversion rate, stable voltage, and reliable circuit protection.
Whether it's taking or giving the charge, the power bank is able to quickly respond to overcharging, overheating, short-circuiting and other situations, ensuring safe charging as well as improved efficiency.
Supports low current charging
Charge your Mi Band and your Bluetooth headphones with the 20000mAH Mi Power Bank 3 Pro.
The added heat-sensitive resistors and temperature control mechanisms ensure the power bank remains within a safe temperature range.
Input overvoltage protection
Excess voltage is prevented from damaging the device the power bank is charging.
Output overvoltage protection
Voltage is automatically reduced or turned off when smart sensing detects excess voltage to protect the device the power bank is charging.
Short circuit protection
In the case of a short circuit, the motherboard and battery are protected.
Input overcurrent protection
Current is automatically reduced or turned off when smart sensing detects excess current to protect the power bank.
Battery overcharge protection
The added specialized battery protection effectively prevents overcharging.
If the product is not working properly, the added circuitry reset lets you reset the device with the press of a button.
Output overcurrent protection
Current is automatically reduced or turned off when smart sensing detects excess current to protect the device the power bank is charging.
Hardware-level battery overcurrent/short-circuit protection
Purely hardware-based overcurrent/short-circuit protection allows for fast response to obstructed battery circuits.
